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.

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.

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.

Asphalt Paving and Sealcoating - The Hard Facts of Asphalt Repair

Asphalt Installation Near Me

People usually see cleaning of asphalt driveways as hard, tiring, and time consuming. What makes it so is the way they do it. First, they know a lot of things should be done. They get confused with what to do first. Some think they can schedule their tasks in a daily manner. The truth is, repairing an asphalt driveway is just as easy as one, two, three, and four!

Pull out weeds. Wear rubber gloves to avoid getting cuts and injuries from pulling weeds. Hold the weeds on their base, and carefully pull out to get their roots. For tough weeds, use gripping tools such as pliers to pull out at least the part of the tough weeds that catch attention.

If it is hard to remove the roots of the weeds, carefully chip out surrounding of the root, when it is already around ½ to 1 inch wide, and 1/3 inch deep, use a filler to smoothen out the surface. Also, use a chipper to smoothen pointed surfaces. Loose stones should be picked up. Use a broom to remove pebbles.
Get rid of soil and spots. For tough stains like oil or gas stains, use of cleaner is advised. Water in high pressure can be used to wash away the detergent or cleaner residue. Make sure that the driveway is completely dry before moving to the next step.

Use fillers for cracks. For small cracks, use asphalt-emulsion fillers and smoothen the surface. For cracks that are at least 1 inch wide, use cold patches. Pebbles or stones can be used to fill in most of the opening first. Cement can be an option, but this may take quite a while to completely dry. Cover the patch with plywood and drive it over. You can leave the plywood there until the patch is completely dry.

Use sealer once the patch is dry. Let the sealer dry before driving over it. Get rid of excess sealers.For best results, make sure that kids will not dig out the patch or filler out as soon as you turn your back. Remove pointed parts or surfaces as these might eventually lead to injuries. After cleaning and repairing the driveway, make sure that the cars using it are also clean. As much as possible, if mud, or oil, or gas puddles up on the driveway, immediately clean them up.
