Restore The Quality Of Driveways With Use Of Asphalt Patching Technique

By Cornelia White


The durability of asphalt will depend on how well it is maintained when laid down. Asphaltic material requires continuous preventive maintenance to protect and keep it in good condition. Although it can survive for long, on the other hand, if proper care is not taken, it can easily lead to premature failure. With help of asphalt patching contractors, you can repair sections of your roads or driveways that are damaged especially those with localized crack damages.

With time, as the blacktop material ages, it deteriorates in quality. This is caused by the oxidizing process of asphaltic material. As the asphaltic material ages, it changes it molecular structure and becomes lose and unbinding. The beautiful jet black color dies away as the material turns lighter grey.

The patch method is best used in localized repairs. If you have a few areas that need to be restored, then the method may be appropriate. With time, asphaltic blacktop suffers from the effects of sunlight, water, and substances like salt and gasoline products. Ultraviolet rays lead to hardening and unraveling of blacktop material. As the rays heat the surface directly, they accelerate the oxidizing process leading to unbinding of asphaltic material.

When the grounds shift following the application of asphaltic material, this may lead to formation of sink holes. These are also repaired through use of patches. Potholes are formed in roads that suffer from moisture intrusions and effects by freeze-thaw cycle. Ultraviolet rays from the sun heat and bake the blacktop of pavements making it unstable with time.

The surface begins to unravel and you can find loose aggregate stones on the surfaces wearing or unbinding from the blacktop. The adhesive bond of asphaltic is reduced as weather elements continue to act on it and with time, it loses its binding properties and becomes loose. Cracks start forming on the surfaces, and when they are not repaired, they can cause many problems.

When the surface is acted upon by moving vehicles weight, it can collapse easily leading to sections of areas which need properly repair. The patch technique is used in areas which have receive extensive damage such a potholes, sink holes, alligatored cracks, and other large damages particularly those which are localized or affect a small area.

As drivers try to avoid hitting the potholes, they may hit other oncoming vehicles leading to accidents. The owners of premises need to make sure they repair the damaged sections of roads to prevent accidents from occurring. Cold patch is applied on the damaged area without heating it. The ground is first prepared by removing any debris and cleaning it properly to ensure it is dry and free of any loose materials.

The cold patch process does not require the use of heavy rolling machines and it is not dependent on warm weather for application. One reason why the asphaltic repair crew uses the cold material is that it retains its pliable properties as the temperature drops. Hot asphaltic mix may also be used to patch the damaged areas of pavements. The asphalt patching contractor will determine which procedure works best and affordably while providing long lasting solutions.
