The material for a residential parking lot is a significant capital expenditure. For apartment complexes and multi-family developments, the decision between asphalt and concrete involves balancing current budget constraints against long-term maintenance. Both materials provide a solid foundation but perform differently in Colorado’s climate. Below, we outline how asphalt and concrete compare across the three most critical categories: cost, performance, and durability.
The most immediate difference between the two materials is the cost. Asphalt is more affordable to install upfront. Because it is a petroleum-based product that can be laid quickly, the labor and material costs are lower. For a large multi-family parking lot, this allows property managers to allocate funds toward other site improvements like landscaping or lighting.
Concrete requires a higher initial investment. The materials are more expensive and the installation process is more labor-intensive. Concrete requires specialized forming and longer curing times. However, concrete is often viewed as a "one-and-done" investment. While asphalt requires regular sealcoating every few years, concrete can go decades with less intervention.
Asphalt is a flexible pavement. It can expand and contract slightly with the earth, which makes it resilient against freeze/dry. Because asphalt is black, it also absorbs solar heat. In the winter, this helps melt snow and ice faster. In the summer, it can contribute to the "heat island" effect, making the parking lot significantly hotter.
Concrete is a rigid pavement. It does not flex; instead, it is designed to bridge over minor gaps in the subgrid. While it stays much cooler in the summer, it does not aid in snow melt during the winter and can be prone to cracking if the ground beneath it shifts significantly.
When it comes to longevity, concrete is the clear winner. A well-installed residential concrete lot can easily last 30 to 50 years. It is highly resistant to heavy vehicle loads such as garbage trucks or delivery vans that might cause rutting in asphalt.
Asphalt typically has a lifespan of 15 to 20 years. However, its durability is tied directly to its maintenance schedule. Without regular asphalt paving repairs and sealcoating, water can penetrate the surface, leading to oxidation and potholes. The advantage of asphalt's durability profile is that it is "renewable." You can mill off the top layer and replace it without tearing out the entire foundation, a process that is much more difficult and expensive with concrete.
The maintenance requirements for asphalt versus concrete are almost opposites. For asphalt, you can expect a proactive schedule. To get the most out of an asphalt lot, you should sealcoat it every three to five years and fill cracks as they appear. This prevents the binder from drying out and turning gray and brittle. For concrete, maintenance is reactive. Beyond occasional joint sealing or power washing to remove oil stains, concrete requires very little. If a section does fail, however, you usually have to replace an entire slab rather than just patching a small hole.
If you are managing a high-end luxury complex where aesthetics and long-term stability are the priority, the clean look of concrete services may be the best fit. It provides a premium feel and eliminates the need for frequent maintenance closures that can annoy residents. If you are working with a tighter budget or managing a sprawling complex with massive square footage, asphalt is a good choice. It allows for a functional, safe parking surface at a fraction of the cost, as long as you are disciplined about maintenance.
Regardless of which material you choose, the quality of the subgrade preparation is what actually determines the life of the lot. Choosing an experienced contractor ensures your parking lot stands up to the elements.

Owning one property is already stressful enough because things are fine until they’re suddenly not. You find one issue, which escalates to three issues, which escalates to too many to count.
Investing in additional properties means more pressure, more time, and more expenses. Multiple problems may spring up among four different properties, leaving you thinking: What problem do I tackle first?
The best approach to property management is proactivity. Creating a maintenance program for each building is critical to preventing catastrophic structural or foundational issues that can devastate property value and curb appeal. One of the top maintenance tasks to feature in your program is driveway and parking lot maintenance.
Most commercial properties feature asphalt lots or driveways because asphalt is strong, easy to install and repair, and it handles Colorado’s freeze-thaw cycles better. Although asphalt is durable, it does need maintenance every few years.
Schedule an inspection if you notice any of the following:
As a best practice, we recommend inspecting your driveways and lots after winter and note any of the above signs.
One of the most challenging decisions as a property owner is knowing which issues need your immediate attention (and money) and which ones could be put on the backburner until your budget bounces back.
Potholes are a significant warning sign that your asphalt is failing. Over time, asphalt can weaken and when used in high-traffic areas like parking lots, traffic load can cause the weakened spots to break.
Holes in the asphalt aren’t just ugly. They’re a safety risk for drivers. If you don’t take care of the problem, customers could damage their tires or misalign their wheels or trip when they’re walking to your storefront. Potholes will only get worse over time, so you need a professional to fill and seal them.
Like potholes, sinking and uneven areas are safety risks and can result in tire damage and slip-and-fall injuries. They occur when cracks and depressions aren’t addressed and the asphalt’s sub-layer collapses. Depending on the severity of the damage, full-depth patching (R&R) may be the most cost-effective option.
Small cracks will eventually need to be addressed because they’re openings for water intrusion, and over time, can lead to fatigue cracking (also called alligator cracking), a spider web of lines that can turn into potholes. If you catch them early, you can fix them with a more cost-effective repair method: crack sealing.
“Raveling” is what we call asphalt that’s deteriorating. You’ll know it’s deteriorating because there’s no binder left to hold the asphalt materials together, leaving loose gravel and aggregate stone everywhere. Deteriorating asphalt, like everything else, can pose safety risks for pedestrians and employees, especially because once deterioration starts, it evolves rapidly.
As a general rule of thumb, we recommend getting most issues inspected/taken care of eventually, but there are a few low-risk issues that don’t require your immediate attention.
If there are small cracks (around or smaller than ¼ inch), write it down as a concern, but don’t prioritize it over something critical like potholes or depressions. You can fix small cracks yourself with crack filler, or wait and schedule professional crack sealing and sealcoating services, which will add multi-year protection to your lots and/or driveways.
Minor depressions (emphasis on minor—if it’s sinking, schedule repairs immediately) can be fixed with small patching, but will eventually need to be addressed on a larger scale. If your budget is tight, make a note that you will need to schedule R&R/full-depth patching eventually.
Fading is both an aesthetic issue and an ADA compliance risk if striping is faded, too. Faded ADA markings can have legal and financial consequences, so they shouldn’t be put off for too long, depending on the severity of the fading. This issue can be easily resolved with line striping and sealcoating services.
Crumbling still isn’t a good sign because it means the asphalt is losing structural support, but edge repairs are far less expensive than fixing severe longitudinal or alligator cracking. All that’s needed is crack sealing and/or patching.
Staying on top of maintenance is the best way to lower your repair budget, reduce safety risks and liabilities, and prevent unnecessary downtime. Asphalt Doctors helps commercial property owners throughout Northern Colorado and the Front Range take care of their driveways and lots. As a full-service contractor, we offer maintenance programs, crack sealing, patching, sealcoating, installation, milling, and more.

Some business owners don’t give much thought to their parking lot. They may hire the lowest bidder to throw down some concrete and call it good. But in a few months, they’ll be regretting that decision. There’s a science to a properly functioning parking lot, and grading and drainage play important roles in the longevity, safety, and usability of a commercial parking lot.
With 30 years of experience paving parking lots, the Asphalt Doctors are experts at incorporating the best drainage design. We break down the essentials of parking lot grading and drainage below.
We’ve all seen a flooded parking lot after a big rainfall. Chances are, if you didn’t really need to go to that store or business, you drove away. Poor drainage can lead to lost customers for your business. And in a state with its fair share of unpredictable rain (and snow melt), those missing customers can add up.
The consequences of poor drainage go far beyond lost revenue. Say a customer does park in your flooded lot and walks toward your building—only to slip and fall in a puddle. If they can prove that you knew your parking lot was dangerous and didn’t fix it, you could be facing a lawsuit.
Beyond customers, however, standing water affects the quality of your pavement itself. Excess water can lead to cracks and potholes in your asphalt. This weakens the structural integrity of your parking lot, and it will need to be resurfaced or even replaced sooner than if it had proper drainage.
These damaging effects are even more pronounced in Colorado, where we have a more intense freeze-thaw cycle than other states. If your parking lot is full of standing water under the warm afternoon sun, it could freeze by that night. This means that each little crevice that water had pooled in will expand when the water freezes—leading to larger cracks across your entire lot.
If your parking lot isn’t thoughtfully designed, water may naturally flow towards your building. This water runoff can lead to all kinds of issues, including flooding, blocked entrances or exits, and damage to the foundation of the building.
There are a few techniques you can use to ensure water doesn’t pool on your pavement. Many commercial parking lots use a combination of these asphalt drainage solutions.
Sloping the pavement slightly allows water to flow where you want it to, such as towards a drain. A professional can recommend the proper grade for your lot based on the natural inclination of the property and where you want to funnel the water.
There are several drain types you can use in your parking lot. A common choice is a catch basin. On the surface, a large metal grate is installed, which will allow water and small debris to pass through. Underneath this, a plastic or concrete basin allows the debris to settle, then redistributes the water into the larger wastewater system.
Rather than directing all the water to a single catch basin (or two), a trench drain is a long, skinny drain that can collect more water at once. A parking lot will be divided by the trench, and either side will be angled downward slightly toward the long drainage system. Water is then removed via pipes underneath the lot.
If you don’t want a visible drain in your parking lot, a French drain could be the perfect solution. This system uses a pipe buried in a gravel-filled trench. Water seeps into the gravel and then into the pipe, which redistributes the water off-site.
One issue with drains is that they can become blocked from leaves, trash, or other debris. A workaround is to instead install permeable pavement, where the water passes through the concrete or asphalt itself. Similar to the French drain, this system works by having a layer of gravel underneath the porous pavement, which absorbs much of the moisture and then slowly releases it into the ground over a longer period of time.

When you invest in commercial asphalt paving for your Colorado business, you expect it to last for years. However, fuel spills and chemical exposure can dramatically shorten your pavement's lifespan. Understanding how these substances affect your asphalt and what you can do to protect it is crucial for maintaining your property's value and safety.
Asphalt pavement consists of aggregate materials (crushed stone and sand) bound together with asphalt binder, which is a petroleum-based product. When gasoline, diesel, motor oil, or other petroleum-based substances come into contact with your pavement, they act as solvents on the asphalt binder. Both the binder and these fluids come from crude oil refining, so they share similar chemical properties, and spilled fuel quickly dissolves the bonds holding your pavement together. Once the binder begins breaking down, the aggregate becomes loose and unbonded, creating soft spots that are easily damaged by traffic or sharp objects.
Colorado's winter weather presents another challenge: de-icing chemicals. The Colorado Department of Transportation primarily uses liquid de-icers on roads along with traditional rock salt. The good news is that properly installed hot-mix asphalt is engineered to withstand freeze-thaw cycles and is not directly damaged by salt or de-icers themselves.
However, de-icers can indirectly accelerate pavement deterioration if your asphalt already has cracks or damage. Salt and de-icers keep water in liquid form at lower temperatures. This means the freeze-thaw cycle, where water enters cracks, freezes, expands, and breaks apart the pavement, can now occur at temperatures well below freezing. If your commercial asphalt is already compromised with cracks or potholes, salt will allow more water to penetrate deeper into these openings before it eventually freezes. This can widen existing cracks and worsen pothole formation.
Without damaging fuel or chemicals, properly maintained asphalt can last 20-30 years. However, untreated fuel contamination and ongoing exposure to harsh conditions can force replacement in less than 10 years. Damage may initially appear as discoloration and surface staining and the asphalt may feel softer in affected areas. As the damage advances, the surface begins "raveling" or losing aggregate as the weakened binder fails to hold stones in place. This creates a rough, deteriorating surface. Water pooling in these damaged areas carries additional oils and chemicals deeper into the pavement, accelerating deterioration.
Fortunately, there are proven strategies to protect your commercial asphalt from fuel spills and chemical damage:
Sealcoating creates a protective barrier that prevents petroleum products from penetrating the surface and binding with the asphalt binder. For commercial parking lots that experience regular vehicle traffic and potential fuel spills, industry experts recommend sealcoating every 2-4 years.
Immediately absorb liquid spills with absorbent materials like kitty litter or specialized absorbent pads, working from the outside edges toward the center. Allow absorbents to sit for 15-30 minutes, then sweep them up. Follow with a degreasing agent specifically designed for asphalt, scrub thoroughly, and rinse.
Fill cracks as soon as they appear, ideally before winter arrives in Colorado. This prevents the freeze-thaw cycle from expanding damage and reduces the risk of de-icer-related deterioration.
Schedule professional inspections at least annually, preferably in spring and fall. Catching problems early saves thousands in repair costs compared to addressing major structural failures.
Your commercial asphalt is a significant investment in your business. Fuel spills and chemical exposure don't have to mean premature replacement. By understanding the science behind pavement damage and implementing a proactive maintenance program, including regular sealcoating, prompt spill cleanup, and crack repair, you can extend your pavement's life by decades.

It comes as a surprise to many homeowners that not all asphalt is created equal. Some do better in harsh weather conditions, while others are best for heavy traffic. After all, the same asphalt used on roads isn’t the same for a driveway, sidewalk, or freeway.
When starting on an asphalt paving project, it’s not always clear where to begin. Today, we’re here to help you make the right choice with a handy guide to the ideal asphalt mixes for residential paving.
Also known as bitumen, blacktop, or HMA, hot mix asphalt is the most widely used in major projects. This type is known to be highly durable and weather-resistant, but there are a few sub-types, each with its own performance properties and best applications:
Warm Mix Asphalt (WMA) requires less oil-fuel consumption, emits fewer emissions when creating it, and is less harmful to the environment when used. Warm mix asphalt is therefore an eco-friendlier alternative to hot mix asphalt from production to laying. It’s quickly becoming the new standard across municipalities, but since it's a newer pavement application, long-term performance information is limited. However, it is known to be highly durable and versatile, from the data that is available.
Porous asphalt, or permeable pavement, is a subtype of hot and warm mix asphalt that is best for stormwater management. As it is designed to naturally filter water and reduce pollutants carried to the waterway, it is both eco-friendly and smart for managing moisture. This type of asphalt is best for homeowners in rainy areas or where flooding is more common.
Now that you know the different asphalt options available, how do you decide which one is right for your project? Beyond basic factors like durability and climate, it’s also worth thinking about the final texture, appearance, and overall feel you’re aiming for. Here’s how hot, warm, and cold mix asphalt stack up:
Hot mix is the go-to choice for long-lasting, high-traffic surfaces. Because it’s poured at high temperatures, it compacts tightly and creates a smooth, refined texture that looks clean and professional. If you want a driveway or roadway that’s durable, weather-resistant, and has that classic sleek blacktop appearance, HMA is tough to beat. It performs especially well in warmer climates, where cracking from freeze-thaw cycles is less of a concern.
Warm mix asphalt is produced at lower temperatures, which makes it more environmentally friendly and easier to work with than hot mix. It offers a texture similar to HMA—smooth and uniform—but with slightly more flexibility during installation. This makes it a great choice for projects where you want solid durability but also value reduced emissions or need to pave during cooler temperatures without sacrificing quality. Think of it as the balanced, versatile option.

For commercial property owners, a parking lot is more than just a necessary space for employees and customers; it’s a crucial asset that impacts safety and appearance, and it can add high maintenance costs when quality-control measures are underestimated.
The correct type of grading and installation techniques are essential, but long-term commercial asphalt paving performance and lifespan depend heavily on two key quality-control measures: density testing and mix design verification.
Compaction density is a critical factor for asphalt pavement performance. Asphalt must be compacted to a specific density range to reduce air voids, which lowers oxidation, moisture intrusion, and shear deformation; together creating greater structural integrity. When pavement is under-compacted, water and air penetrate the surface and accelerate oxidation, weakening the asphalt binder and allowing premature cracking and potholes.
While under-compaction can create a number of issues, over-compaction causes its own problems. When pavement is over-compacted, there is reduced flexibility, leading to flushing and bleeding, especially during warmer months. The goal is between 92-96% maximum density, balancing the strength and flexibility for even vehicle load distribution and moisture resistance.
Continuous testing of compaction density during a paving project is critical to verify the job is done correctly. However, it also helps the client with:
To ensure the goal density is met, asphalt contractors should use field testing throughout the paving process. The two most common methods are:
While the right compaction is key, if the mix design is incorrect, then the asphalt performance will suffer despite the density. Mix design verifications ensure that the asphalt used for the lot meets engineering requirements for the climate conditions, traffic loads, and intended use.
A properly designed asphalt mix will have the correct proportions of aggregate, asphalt binder, air voids, and other elements that allow for flexibility, strength, and resistance to aging. Before a paving project begins, contractors will verify that the mix meets the approved design standards and that the plant-produced asphalt matches those specifications. During the project, samples should be taken to continuously confirm consistency and avoid compromising performance.
When density targets are met, the correct mix design is used, and the proper techniques are implemented, a parking lot’s lifespan can be 20 to 30 years, depending on traffic volume and maintenance practices. Routine sealcoating, crack filling, and timely repairs can all extend service life while reducing long-term costs.
Here at Asphalt Doctors, we make sure we’re paving the right way the entire way. We verify the asphalt mix, use both field density testing methods, and test continuously so you know your lot performs throughout its service life. We are the go-to experts for businesses across the Denver metro area and use state-of-the-art equipment in every paving project.

Heavy trucks put a serious strain on asphalt. If yours isn’t built tough and to the correct grade, it will crack, break, and need constant repairs. At Asphalt Doctors, we know what it takes to build pavement that lasts under the toughest conditions. Here’s what you need to know.
Heavy trucks can weigh up to 80,000 pounds or more, putting enormous pressure on pavement—sometimes over 10,000 pounds per tire. Add in frequent stops, sharp turns, and shifting weight, and the stress on the pavement multiplies.
When pavement isn’t built for this kind of punishment, it starts to break down, causing cracks, and potholes to develop. These issues cost you time and money in repairs and downtime. That’s why designing pavement specifically for heavy truck traffic matters. It keeps your surfaces safe, operational, and durable.
When we talk about “grades” of asphalt, we’re really referring to different mix types (or “asphalt gradations”) and how they’re engineered to respond to load, environment, and long‑term performance. In industrial or heavy‑use settings, it’s especially critical to choose a mix that stands up to high stress, traffic, and potential for deformation.
Below is a breakdown of the common categories and a guide to selecting the correct mix for each project.
| Mix Type | Characteristics | Use Cases |
| Dense-graded | Well-graded and relatively impermeable. Can be reinforced with high-strength fibers. | Suitable for many layers, including surface, binder, or base layers. You can choose a finer or coarser gradation depending on load and texture needs. |
| Stone Matrix Asphalt (SMA) | Gap-graded, with a skeleton of stone supporting loads, plus a rich asphalt matrix. | Highly rut-resistant. Best for high-traffic, heavy-duty surfaces for the best durability and deformation resistance. |
| Open-graded | Designed for permeability, water drainage, and surface friction. Can also help with noise reduction. | Generally used for the surface course and is not structural. |
Additionally, within dense‑graded mixes, the “nominal maximum aggregate size” (NMS) is used to classify mixes: e.g. 9.5 mm, 12.5 mm, 19.0 mm, 25.0 mm, 37.5 mm, etc. The larger the NMS, the more coarse aggregate, which can resist heavier loads but has trade‑offs in texture, compaction, cost, and appearance.
Most asphalt paving jobs—especially industrial, commercial, or roadway projects—use multiple types of asphalt mixes layered together. This is standard best practice, and it’s done to optimize performance, cost, and durability for different parts of the pavement structure. So the top layer can use any of the above types of mixes but most likely an open-graded mix, the intermediate course will use dense-graded mixes, and the base course will use even more coarse and denser mixes to establish structural stability.
Here’s a simplified process you can follow when specifying asphalt for a project:
For new construction, run a structural design to find how thick your asphalt layers need to be to carry the design loads. For rehabilitation, evaluate the existing structure and determine how much overlay (or how deep replacement) is required. If you’re not sure, it’s best to work with an asphalt contractor with the knowhow to get you the correct asphalt design your project needs.
The Federal Highway Association (FHWA) uses ESALs (Equivalent Single Axle Loads) over 20 years to categorize traffic:
Heavy truck traffic, slow-moving loads, or industrial traffic intensifies demands (e.g. more risk of rutting).
For low traffic, dense‑graded mixes are almost always sufficient. For moderate traffic, dense‑graded still works well, though at higher end you might consider SMA or open-graded with friction course (especially if friction or drainage is desired). For high traffic (especially with trucks or slow loads), any mix type is a candidate, but SMA often becomes attractive for its rut resistance.
You’ll also need to decide the size of the aggregate: heavier traffic favors coarser aggregate (e.g. 19 mm, 25 mm, or thicker) to resist deformation.
From the total thickness, subtract what you’ll allocate to the surface course. The remaining thickness must be allocated among intermediate (binder) or base layers. For each remaining layer, reference mix type suitability tables to pick an appropriate mix. See figure 3 in the Federal Highway Administration’s guide.
Continue “building downward” until you’ve assigned all required layers.
Heavy truck traffic demands pavement that won’t quit on you. Don’t settle for quick fixes that lead to costly repairs down the road.

If you’ve ever seen a jagged line across your driveway or parking lot, you’ve witnessed the early signs of pavement wear. While they might seem harmless at first, untreated cracks can grow fast, especially in Colorado’s unpredictable climate. Fortunately, crack sealing is a cost-effective, preventative measure that can add years to the life of your asphalt.
In Northern Colorado, pavement is put to the test year-round. Water seeps into tiny cracks, freezes overnight, and expands during freeze-thaw cycles in the spring and fall. These can quickly turn minor surface flaws into major damage. High-altitude sunlight and low humidity also cause oxidation and drying, making asphalt brittle and more likely to fracture. Vehicle traffic also contributes significant stress to pavement.
Crack sealing works by addressing the problem before it gets worse. A professional will first clean the crack thoroughly, then route it (if needed) to ensure a clean edge for bonding. A hot, rubberized sealant is applied that penetrates and adheres to the asphalt, forming a flexible, waterproof barrier. This prevents water infiltration and keeps out debris, stopping the crack from growing and protecting the pavement’s base structure.
The sooner you seal a crack, the better. Water infiltration is one of the leading causes of pavement failure. Once moisture reaches the sub-base, it compromises the structural integrity of the entire surface. By sealing early, you can prevent potholes, surface erosion, and the need for more expensive repairs down the road.
Crack sealing is also a smart long-term investment. According to the Federal Highway Administration, preventive maintenance like crack sealing can extend the life of pavement by as much as five to ten years. This helps avoid full resurfacing or reconstruction, which is more costly. Regular maintenance also enhances curb appeal and improves safety by reducing tripping hazards and vehicle damage.
While DIY crack fillers exist, they often lack the durability and adhesion of professional-grade materials. More importantly, proper application requires specific tools, like air compressors, heat lances, and pour pots, as well as expert knowledge of routing, sealant selection, and temperature conditions.
Professional contractors follow industry best practices to ensure long-lasting results, including pre-heating the crack for maximum adhesion and using quality sealants rated for Colorado’s climate. This level of detail ensures the seal remains intact through temperature extremes and heavy traffic.

Your driveway takes a beating every day, from weather to vehicle traffic and weight, and that damage adds up over time. Sealcoating is a simple and cost-effective way to extend the lifespan of your asphalt driveway and keep it looking sharp. Let’s dive into why asphalt sealcoating is a smart move for both your wallet and your property.
Sealcoating is a liquid mixture that typically includes asphalt, water, fine aggregate (a coarse mixture usually consisting of sand and crushed stone), and chemicals, which together form a protective barrier against the elements. Professional application is quick and painless. The surface is cleaned, the special sealant is mixed to the perfect consistency and coverage, and then is applied across the driveway surface with a dry and curing time of about 24-48 hours.
Sealcoating offers a quick and cost effective repair that improves the safety and longevity of your driveway. Here are the biggest benefits you can expect:
Water is a bitter enemy to asphalt surfaces. First, it wears down the surface, creating dips and leaking into small crevices, and then gradually expands its reach into the pavement with every rain. When that water freezes and thaws (a Colorado specialty), it expands and contracts, expanding the cracks and fissures in and underneath asphalt surfaces.
It may not seem like much as it’s happening, but that’s precisely the problem: before long, those small cracks will widen, some will become full-on potholes, and your driveway will look like it’s been through a war. Even if it’s still usable, you’re looking at full-on driveway replacement, which is far more expensive than sealcoating.
Sealcoating, by contrast, slows down this cycle by creating a barrier over your asphalt, preventing water from seeping in and doing damage. With that extra layer of protection, you’re avoiding expensive and frequent asphalt repair services down the road.
We love Colorado’s constant sunshine, but for your asphalt, it's a different story. Prolonged exposure to UV rays dries out the surface. This is called oxidation. The problem here is that a dry driveway means that it’s brittle due to a loss of oils and a loss of its original flexibility, and more likely to crack under vehicle loads and routine use. Over time, UV exposure also leads to unsightly fading and deterioration, i.e. that grey color you’ve probably gotten used to.
In addition to keeping out moisture, sealcoating’s protective layer acts like sunscreen for your driveway. In this way, you’re investing in a longer-lasting, better-looking surface that resists fading and stays strong for years to come. In fact, after sealcoating, your driveway will look like it’s brand new—the dark color and level surface gives a clean and well-maintained appearance. If you’re considering selling your home, sealcoating is a great way to boost curb appeal and impress potential buyers without paying the full price of a new driveway installation.
Think of sealcoating as an investment in your driveway’s future. Sealcoating costs a fraction of what you’d pay for major repairs—typically between $0.15 to $0.25 per square foot, compared to a full replacement, which can run you $3 to $5 per square foot. Ignoring small cracks or surface damage can leave you with expensive potholes or other large-scale repairs. By staying on top of preventative asphalt maintenance, you save significant money over time and avoid the stress of dealing with a driveway that’s falling apart.
Cracks and potholes are more than just eyesores—they’re potential safety hazards. If someone trips and falls on your driveway, you could end up dealing with medical bills or even lawsuits. An uneven surface can also cause vehicle damage, from tire blowouts to suspension issues. So when you sealcoat your driveway, you're making it safer for everyone as well as preventing secondary, unforeseen expenses.
It’s generally recommended that you sealcoat your driveway once every two to three years. However, the Colorado elements, freeze-thaw cycles, and blazing sunshine are not going to go easy on your asphalt, so you might want to consider a sealcoat. Looking to work with the best? Submit a request with the pros at Asphalt Doctors today, and you’ll be taking in the sweet sight of a freshly sealcoated driveway in no time.
Potholes are more than just a nuisance—they’re a safety hazard and can quickly lead to expensive damage if left unchecked. Whether it’s your driveway or a business parking lot, getting those holes patched up promptly is key to keeping your pavement smooth and durable. Asphalt Doctors knows the best pothole repair methods to ensure your asphalt stays in top shape year-round.
Potholes don’t just appear out of nowhere—they’re usually caused by water infiltration, freeze-thaw cycles, and heavy traffic. Water seeps into the cracks, freezes in colder months, then expands and contracts, weakening the asphalt over time. Neglecting repairs lets these cracks turn into full-blown potholes, leading to bigger problems like unsafe driving conditions and costly damage to your vehicle or pavement.
Sometimes you don’t need to see a bunch of obvious potholes in order to get ahead of needed repairs. When you start noticing visible cracks, standing water, large holes, or rough, uneven surfaces, it’s time to think about pothole patching. Cracks are obviously not the same thing as a pothole, nor do they necessarily use the same repair methods, but the one will undoubtedly lead to the other.
Regularly inspecting your asphalt for these issues can save you from bigger headaches down the road, and catching problems early allows for simpler fixes and can prevent more expensive, widespread damage—saving your wallet and your pavement from a rough future. If you see potholes themselves, this is of course a sign that pothole patching is needed lest they grow larger.
Skin patching is a quick and relatively cheap fix that gets the job done for smaller, less severe potholes. Essentially, it involves cleaning the hole, filling it with new asphalt, and smoothing it out. While it’s cost-effective and ideal for minor damage that’s generally contained to the surface, it’s not a long-term solution for major potholes that reach deep into the asphalt. This method tends to be used when looking for a fast fix before a bigger repair is needed.
Full-depth patching is the exact opposite of skin patching. It’s the usual solution for more severe potholes where the damage extends deeper into the asphalt or even threatens to compromise the structural integrity of the surface as a whole. This method involves removing the damaged section entirely, down to the base, and replacing it with fresh asphalt.
While this is certainly more labor-intensive and costly in the short term, the result is a lasting repair, preventing further deterioration and repeated repair costs. If your pothole is large, deep, or located in high-traffic areas, full-depth patching is the way to go.
Infrared patching is an innovative solution that has surged in popularity due to the speed and precision in which it can be completed, all without sacrificing quality—in fact, it will actually improve it.
The process involves using advanced equipment to heat the surrounding area of the pothole, remove any damaged sections, then subsequently blend new asphalt to create a smooth, uniform surface. This method not only fixes potholes but also increases the overall strength and durability of the surrounding area, making it a fantastic long-term option. Maybe the best part is that it can often be completed in as little as 10-20 minutes! That means less down time and minimal interruptions—perfect for high-traffic roads and parking lots.
The optimal solution for your pothole woes may vary depending on the severity of the damage, but acting quickly with a fix will undoubtedly save your wallet and your peace of mind. Contact Asphalt Doctors today to ensure your pavement stays smooth, safe, and durable for years to come.
