Customers, clients, guests, and occupants can use the pavement in the same day!
Continue reading to learn some great tips on how you can shorten the amount of time it takes for the cold patch asphalt mix to harden, and drastically cut down on turnaround time, from project start to finish.
Ease of Use
The primary reason why this product is the go-to choice for small hole repairs in asphalt pavements is the ease of installation. There is no long, extended process of preparing or mixing materials. Instead, the air does most of the work. You simply pour the mix directly into the hole, compact it with simple manual tools (metal tamper or piece of lumber), and leave it to air dry. The mix turns into a permanent surface patch after extended contact with air.
The drying process, also known as curing, is very important to establishing a solid, stable surface that lasts a long time. If you want a permanent repair for your asphalt, you need to make sure the entire process is done correctly. If you want to speed up the curing stage of your pavement repair project, you can try a few recommended tips.
You can use gravel to create a more dense space within the hole, which may help to establish lasting strength. Just fill the hole with gravel, little by little, while using your compacting tools to compress the gravel with each layer. Do not fill the hole all the way to the top; be sure to leave 2 inches of space below the surface line for your cold patch mix.
Pouring Your Mix
As you pour your mix, exceed the surface line by half an inch. This means that your mix should go over the top of the hole by a ½ inch. Then use your compacting tools to compress your material down until it is properly flattened. You may need to repeat this step two or three times to get a proper fill.
Asphalt cold patch mix cures by having contact with air. You can speed up the drying process by using hair dryers or commercial paint dryers. If you are going to use a hair dryer, you will need to manually operate it in a steady, sweeping motion to ensure even curing. The material is near dry when you cannot easily press into the surface with your hand.
Large-Scale Pavement Repair
For large-scale pavement repair jobs, you need a professional paving company. They have the training, equipment, and resources to provide dependable work in a convenient time frame. Be sure to choose a company that is licensed, bonded, and insured, and retains decades of experience in the road construction industry.

Asphalt driveways can last as long as any hard surface if installed and maintained properly. However, usually the weakest point of the driveway is the edge. Edges are prone to several defects. The most common defect is cracking. Cracks generally form parallel with the edge of the driveway. This phenomenon happens usually when expansive soil is present under the driveway. The soil expands and contracts causing cracks that eventually transmit through the asphalt surface. Installing a decorative edge made from cobblestone or brick pavers will interrupt the point of expansion where the asphalt meets the yard. The edge will keep the asphalt from shifting; thus eliminating the cracking in the pavement.
Another source of problems is invasive vegetation. Zoysia grass and chickweed will easily migrate or expand through asphalt, especially fresh asphalt that is less than 3 years old. Grass can grow into an asphalt driveway by as much as 3 feet if not properly attended to. Controlling invasive grasses typically involves a regiment of spraying the edge with a herbicide to prevent growth of grass. Doing this works well, but isn't 100% effective. Zoysia and Chickweed spread by sending out runners under the soil. A home owner trying to protect their driveway might be satisfied with the progress they have made with herbicide treatments because they have kept an edge free of vegetation.
But eventually you may still see some sprouts pop up through the asphalt because a runner was able to escape the effects of the herbicide by traveling underground. Decorative edging installed on asphalt driveways by a qualified paving contractor will eliminate the potential of migrating grass invading the asphalt. When cobblestone or paver bricks are installed properly, it will create a solid barrier between the yard and edge of the driveway. Substrates used to hold the edge is non porous, therefore it leaves no voided areas for vegetation to grow. If invasive grass is left unattended on an exposed asphalt edge it will eventually ravel the edge. Cobblestone or brick paver edging will prevent damage from grass.
Decorative cobblestone and paver edges also keep vehicles from driving off the edge of the driveway. Driving off and on an edge of an asphalt driveway will eventually cause the edge to ravel, or break off. Not only is this an expensive repair, but it also leaves the home owner's yard not looking its best. Repetition will rut the yard and cause a bare spot, which eventually turn to mud. Decorative edges installed properly will reinforce the edge of the pavement, and also create a curb. The curbing effect will keep vehicles on the driveway and out of the yard.
Another important feature of decorative edging is its ability to control drainage. Not all, but some home owners desire a protective barrier against erosion or unwanted rain water. This is generally achieved by installing a machine curb or roll curb on the edge of the driveway. Machine curbs and roll curbs are formed from asphalt material. A decorative edge constructed of cobblestone or paver bricks can achieve the same results and look better doing it. A homeowner that has unwanted drainage or silt erosion from a neighboring property can be stopped by installing a decorative edge or curb.
Decorative edges add aesthetics and beauty to the home. A properly installed edge by a qualified paving contractor looks great and guards your investment by eliminating defects. Decorative edges can add up to 10 years to the life span of your new asphalt driveway. If you plan on replacing an asphalt driveway, you should consider implementing a decorative edge or curb into the design.
Parking Lot Pavement - Why Sealcoating is Important
You're looking at your asphalt driveway and it appears to be in rough shape. What should you do? Will some repair work do the trick? Should the driveway be resurfaced, or does the whole thing need to be ripped up and redone from scratch?
Perhaps the best thing to do is to consult a few asphalt paving contractors and get their opinions, and (often free) estimates. This article can give you a general idea of what's going on, what to look for in an asphalt paving contractor, and what to include in your contract.
Maintenance is good medicine, but it's not foolproof
Asphalt driveways don't remain smooth and black forever. You can take steps to maintain your driveway by sealing and protecting it, but often the effects of heat, ultra-violet rays, and substances such as salt, oil, gas and grease take their toll. And if those don't get you, then cracking and water penetration eventually will.
Your driveway may be corroded, worn out, or have cracks, which could all warrant a resurfacing job if the condition is severe enough. As a general guide, if repairs are needed on more than 25 percent of the surface, it is more cost-effective to do a hot mix asphalt resurfacing job over the entire driveway.
Say no to cracks!
Asphalt pavement is hard and brittle, and as a result, cracks will develop over time. Ranging from hairline to an inch wide or more, cracks are your driveway's worst enemy because they let water in. In colder climates, freeze-thaw cycles can be very destructive, and can wreak havoc on your driveway if water penetrates the cracks, then expands as it turns to ice. And even in warmer climates, water penetration can cause serious damage. The larger the crack, the more serious the problem, and the sooner it needs to be fixed. Cracks that are left un-repaired will lead to serious deterioration of the pavement and even to the base layers, requiring complete replacement of the driveway - sooner rather than later in colder climates.
Can it be fixed or do you need a new driveway?
Whether you'll need to rip out your existing driveway and install a new one, or if you can get away with resurfacing - or even some patchwork and crack-filling - depends largely on the condition of the base layers, or foundation. However, if cracking covers 3/4 of the driveway, the surface is too far gone to repair. The root of the problems may come from lower down, and a complete overhaul should be considered.
If your driveway has been resurfaced several times with hot mix asphalt and keeps deteriorating prematurely, it is likely a problem with the foundation, and you should consider installing a whole new driveway. Likewise, if there are areas that have depressions or mounds, they should be completely reconstructed from the base. If you have several of these areas, a new driveway might make sense.
Various factors may cause premature wear
Although a properly installed asphalt driveway can last 15 to 20, even 25 years if properly maintained, extreme weather conditions, extra-heavy loads and shortcuts taken during construction can all cause premature wear and failure.
Beware of "traveling contractor" scams
Beware of any asphalt paving contractor who rings your doorbell and claims to have some "leftover materials" from another job, and if you agree to the work "right now," you'll get an amazing discount. If this happens to you, call the police. It is a scam. Reputable contractors calculate the materials they need very carefully, and any small amount left over from a job would never be enough to complete an entire new job. If these con artists do any work at all before taking off with your money, it will most definitely be shoddy.
Tips for hiring an asphalt paving contractor
It is best to deal with registered, bonded, adequately insured and licensed (where companies. Many reputable paving contractors also belong to trade associations, such as the National Asphalt Pavement Association (NAPA), the National Pavement Contractors Association (NPCA), or various state-specific associations.
When hiring a contractor to resurface or install a new asphalt driveway, always get a list of references and check them. Ask references about the quality of the contractor's work, their attention to details, and if the work was competed on time. You can even go and inspect previous work.
What to include in the contract
Once you decide on an Asphalt Paving Contractor, consider these points when drawing up a contract:
Clarify who is responsible for re-hanging gates or other doors, if needed, due to raised pavement levels.
Who will raise any water valves or sewer inlets to meet the asphalt around them - you, a plumber, or someone else? Who pays?
Specify that the surface must be graded to provide proper drainage.
For new installations, specify that the sub grade will be compacted before the base layer is applied.
Specify how many layers are included in the job, a description of the materials that will be used for each layer (sub-base, base and asphalt), and the thickness of each layer when compacted. Two separate layers, or lifts, of asphalt is preferred, totaling at least 3 and preferably 4 inches. Sub-base and base should be at least 6 inches each, comprised of limestone rocks with 3-to-4-inch diameter and 2-to-3-inch diameter, respectively.
Include the payment schedule and a guarantee of the finished product.
Determine whether a building permit is required, and specify that it is the contractor's responsibility to obtain one on your behalf, if needed.
