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.

Use Gravel

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.

Expedited Drying

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.

Paving Specialists Quotes

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.

What Is Asphalt Paving

Asphalt Companies Quotes

Does your asphalt pavement have excessive cracks or potholes even though it was recently redone?

Houston weather with the excessive summer high temperatures, high amount of rain and year-round humidity take a toll on asphalt parking lots. In addition, leaking fluids from cars in parking lots tend to destroy asphalt as well.

When asphalt is not treated with the proper sealant, oxidation occues and dries out the asphalt binder. When this occurs, the pavement loses flexibility and will start to crack. Oxidation is when the sun's ultraviolet rays harden and dry out the asphalt surface. This accelerates erosion and reduces asphalt thickness so that in just a few years the pavement needs to be totally resurfaced.

As oxidation occurs, then the rain, chemicals and other pollutants seep into the cracks and the pavement deterioration begins to rapidly progress. Once the process starts, the damage has occurred.

Applying a sealcoat protects the surface of the asphalt and reduces the damaging effects of oxidation and the Houston weather extremes. This application will greatly extend the service life of pavement as well as enhance the overall appearance. Sealcoating keeps and will even restore the original dark color of asphalt to greatly enhance the overall appearance of the property.

If you were to look at a cross section of treated and untreated asphalt, you will see the difference that a sealcoat makes.

In addition to the improved physical appearance, the sealed pavement becomes a smoother surface to make sweeping and maintenance easier and less costly. The most important aspect is the ability of the asphalt pavement to resist the damaging effects of gas, oil and chemical salts.

What does asphalt consist of?
Asphalt pavement is a mixture of crushed stone (known as aggregates) and chemical binders that glue the mixture together. Over time the sun's ultraviolet rays break down the binding materials allowing moisture to fill in the cracks and subjecting the empty spaces (known as voids) to expand and contract breaking down the integrity of the pavements. This is most noticeable when pavement changes from black to a dull gray. As the process continues, the binding materials continue to weaken until large visible cracks and potholes develop.

What does sealcoating do?
Sealcoating prevents the adhesive qualities of the asphalt binders from being broken down as quickly. The most important benefit is it's ability to prevent premature pavement wear. Sealcoating is a good investment when applying new asphalt pavement and parking lots or when updating those in need of minor repair.

How is sealcoating applied?
First the pavement surface is swept and all visible potholes or cracks are cleaned and filled. The sealcoat is applied using a sprayer to ensure proper thickness. A high quality sealcoat has the proper ratio of additives and fine sand as an aggregate to make the survey more durable and non-slip. We recommend a second coat on roadways and other high volume traffic areas to ensure longer service life of the pavement.

As we mentioned, it is important to fill cracks to keep them from expanding and causing others to form. We suggest using a rubberized hot crack fill material to provide a flexible that reaches into cracks and crevices. We also recommend that during all pavement repairs that you make sure pedestrians and vehicles are kept away until all materials have had time to completely dry.

You can expect these types of pavement repairs will last for many years of normal use.
