Even if you’re driving under the speed limit and minding the traffic rules, the sudden jolt of a pothole can be unsettling and unfavorable for your car. While these roadway flaws are common, learning more about them will help prevent them from developing on your property and warranting the services of a paving contractor. Below is a brief guide to their formation and how to fix and avoid the problem.

Causes

Asphalt consists of a variety of aggregates—sand, rocks, gravel—and a binding substance like bitumen. Over time, the weight of passing vehicles and heat from the sun causes the material to expand and crack, allowing precipitation to leak in. The water pooling underneath the road’s surface will erode and weaken the underlying asphalt. During winter, freezing and thawing add to the issue, expanding these voids. Eventually, a vehicle passing over the affected area will cause the surface to give way, exposing the space beneath.

Repairs

To fix potholes and avoid suspension and tire damage, paving contractors perform temporary and full fixes. In the winter, they usually cover these craters with temporary patches, which fill them for a while. When the weather warms, they clean them out and fill the space with hot asphalt until the outer borders of the hole form a seamless bond with the rest of the road.

Prevention

It’s near-impossible to stop all potholes from forming. But, a paving contractor can assess the drainage patterns on your property and create air pockets to allow the asphalt to expand safely. Doing so eliminates most of the risk. Moreover, you should always repair cracks immediately to prevent water from seeping in.
