Restore Damaged Pavements By Contacting Blacktop Repair Lenox Contractors

By Cecile Ingram


After you have installed paving surfaces, you have to prepare dealing with defects that come thereafter. As the asphalt material ages, it begins to wear out because of effects of sunlight, rainwater, and snow. The paving material will also degrade as it reacts to substances like oil spills and transmission fluids. A blacktop repair Lenox contractor can assist in repairing damaged paving surfaces.

The nature and severity of damages will determine the kind of restoration technique to apply. It is good to regularly inspect pavements and when you notice something unusual like defects, you contact a primed contractor. To prevent extensive and premature damage on pavements, you have to sealcoat the surface. This procedure helps in preserving the quality of pavement surface.

Damages that have started forming on pavement should be dealt with as soon as possible. You should call a contractor to repair such defects. Some of the defects you expect to deal with as such as depressions, cracks, potholes, sinkholes, and upheavals. If you allow defects to remain uncorrected for long, you are allowing more damages to occur.

A change from black color to gray is an indication of a degrading blacktop. The light raveling on pavements is not detectable but it is prevalent. This kind of degradation may not have serious impact on pavements. However, the surfaces can be sealcoated and prevented from further degradation. When raveling persists, the small tiny hairline cracks enlarge and begin to be noticeable.

As the paving surface changes to gray, it starts forming light raveling and small cracks. These defects may not be detected but they continue to persist. With time, the small invisible cracks enlarge and become noticeable. When this happens, you have to prevent them from further deterioration. Enlarging cracks allow moisture and water to enter sub base causing more troubles.

Enlarged cracks begin to allow water to seep and enter sub base layer. You need to understand that water and sunlight are the most destructive factors on pavements. As water enters cracks, it erodes the sub base material leading to structural weakness of the foundation. Since the strength of paving surface depends on the foundation, if the base is weakened, then the blacktop also weakens.

Visible cracks can be restored by use of resurfacing or overlay technique. Driveways and parking lot owners use overlay technique to restore small damages on roads like cracks. This helps in saving money because it entails adding another asphalt layer onto an existing one. However, the method is not suitable in areas that have extensive damages like deep and wide cracks or potholes. You can use other methods like removal and replacement of asphalt especially if the damages are extensive.

Cracks such as fatigued or alligatorred cracking can be repaired through patching. Alligator cracks are caused by excessive loading, thin base or surface, weak surface, sub base or base and poor drainage. Block cracking may be caused by old and dry out mix, too dry mix, and fine aggregate mix material with low absorptive aggregates. Repairing pavements with help of an experienced blacktop repair Lenox contractor helps in increasing the life expectancy of paving surfaces and the strength of the entire road structure.
