Restore Damaged Pavements By Contacting Blacktop Repair Lenox Contractors

When you install pavements, you should expect to deal with various defects as it ages. Asphalt is susceptible to wearing and tearing of the material due to snow, sunlight and rainwater. Substances like gasoline products including transmission fluid and oil spills cause damage on pavements. If you notice that pavements have started degrading, you need to call blacktop repair Lenox contractors to repair them.
The extent of damages assists in identifying the right procedure to be used in repairing the surfaces. You need to inspect paving surfaces regularly and take note of any unusual surfaces. Contractors apply sealcoats to preserve the quality and appearance of pavements. This is a protective method and does not solve problems beneath pavements.
If degradation has occurred such that you cannot sealcoat the paving surface, then you should opt for repairs. Cracks, depressions, upheaval, sinkholes and potholes are some defects you are likely to experience within your pavements. In the initial period of construction, asphalt expands and contracts evenly but as it dries, it starts forming small cracks.
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.
Small cracks that are visible may be repaired through overlays or resurfacing. This is a cost effective repair technique, which seals small cracks at once. However, this method has its bottlenecks such as inability to restore large cracks and major damages. If cracks are small and swallow, overlays may be applied. Another method that could be applied in repairing damage on paving surfaces is removal and replacement.
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.
