4 Common Asphalt Problems and How to Avoid Them

Asphalt surfaces like driveways and parking lots require protection from deterioration to remain attractive and functional. The most cost-effective way to avoid expensive repairs and impending pavement failure is to apply sealcoating in Manteca, CA. That being said, here we will discuss four common asphalt problems and their solutions.

Graying from oxidation

UV rays, heavy traffic, oil, gas, and water intrusion can cause pavement problems in California and beyond. As pavement ages and has continued exposure to dangerous elements, it will begin to fade in color and begin to look a bit gray. Asphalt surfaces have started to dry out and oxidize when this gray color is present. Asphalt becomes prone to cracking and brittleness as the drying process continues. Left untreated, the graying asphalt surface will allow moisture to penetrate deeper layers of the structure through cracks in the pavement. Repairing cracked and graying asphalt is critical to avoid permanent structural damage and costly pavement repairs or replacement.

Raveling

Raveling is another asphalt paving problem that requires continued maintenance to avoid or resolve. The raveling process occurs when the asphalt binder, or bitumen, begins to deteriorate and separate from the sand and stone aggregate it is designed to hold together. As a result, the aggregate starts to come loose and break away from the paved surface, causing surface thinning when the deterioration is allowed to continue.

The once smooth asphalt surface will take on a rough appearance as the aggregate separates and wears away. In addition, Raveling allows water to invade deeper levels of the asphalt surface into the base. When left untreated, continued water intrusion will lead to loss of structural integrity and the need to replace an asphalt surface completely.

Linear cracking

As asphalt surfaces age, longitudinal and transverse cracking patterns are common. These cracks start small and will continue to expand over time if left untreated. Every crack in an asphalt surface, no matter the size, creates an opportunity for water intrusion. In addition, expansion of the pavement from cold and hot temperature changes will allow the cracks to grow larger over time. Therefore, it is essential to clean debris and dirt from these cracks before beginning the repair process to ensure that water intrusion into deeper asphalt layers is no longer possible.

Sealcoating new asphalt pavement between 90 days and a year of initial installation will lock in the bitumen binder and prevent cracks from developing.

Growth of vegetation

When left unfilled, gaps, cracks, and joints in asphalt surfaces will allow the growth of weeds, grass, plants, and trees through the parking lot surface. Vegetation growth can damage an asphalt surface's base and make the area look messy and neglected. In addition, when vegetation is left for continued growth, its roots will begin to erode the deeper asphalt layers and allow for water intrusion and structural damage. Property owners and managers can save time and money by staying on top of asphalt repairs and maintenance before vegetation has a chance to take root.
