The process of repairing and stabilizing deteriorated pavement is complex, and retains methods and techniques that differ slightly depending on several factors. From weather conditions to water drainage, there are many aspects to consider before filling-in or patching-up a pothole. Proper pothole repair is critical in order to protect your investment and achieve the long-lasting pavement stability you desire. Continue reading to learn why accurate pothole repair is so vital, and who to call for commercial paving services you can trust.
Potholes are created as a result of many factors. The most common factors are freeze-thaw cycles. When it rains or snows, water enters the pores and cracks within the pavement. The cycle of contracting and expanding in the pavement causes it to weaken overtime. And with ongoing traffic and inclement weather, the vulnerable pavement will begin to wear away, eventually collapsing and forming a hole.
Pothole RepairThere are two common methods for repairing a pothole. Depending on certain factors, a pothole will require a temporary patch or a semi-permanent repair. Temporary pothole patching often involves a process known as “throw and roll.” It starts filling a pothole with hot or cold asphalt patching material, and then compressing it down manually (hand tamping) or with a paving vehicle. This option is more efficient and less expensive.
Semi-permanent pothole repair is a little more labor intensive since it requires adequate debris removal first, and then pavement cutting to achieve straight, even edges. Once a clean shape is achieved, a hot or cold asphalt paving material is poured inside and then compacted with a roller or vibratory plate.
Pothole prevention starts with a trusted paving company that knows how to assess an area and provide proper pavement installation, taking into consideration sub-grades, water drainage, risk factors, and more. If pavement is not installed and laid properly, it will immediately show signs of defects and instability. Improper pavement installation will surely lead to an increase in pothole formation, and costly pothole repair.
