Why asphalt pavement cracks?

Views:44     Author:Site Editor     Publish Time: 2020-12-11      Origin:Site

Asphalt concrete pavement cracks are roughly divided into two types:

1. One is load-type cracks, that is, cracks mainly caused by driving loads. Under the action of vehicle load, tensile stress is generated at the bottom of the semi-rigid base layer. If the tensile stress is greater than the tensile strength of the base material, the bottom of the base layer will quickly crack until it affects the asphalt surface;

2. The other is non-load type cracks, low-temperature shrinkage cracks and temperature fatigue cracks, mainly temperature cracks; cracks caused by improper construction technology or the use of unqualified materials.

3. The two types of cracks are basically divided into horizontal cracks, longitudinal cracks, mesh cracks and reflective cracks according to their shapes.

How to patch and pave?

When small cracks appear on the pavement, they must be dealt with in time. In the event that cracks aren’t filled, potholes and large cracks will form on your asphalt. Potholes aren’t just aesthetically displeasing, they can also damage the suspension on vehicles over time. Potholes are also dangerous for pedestrians. With JIEHE Crack sealing machine repair, you can feel assured that the large cracks and potholes will be repaired well, and in a timely fashion.

Asphalt Seal Coating should be applied every 2-3 years to preserve the life of your asphalt. This helps protect your asphalt with a protective coating to resist attacks from the elements like sun, rain water, oil, and gasoline. Sealcoating surface treatments also fill in small cracks, removing the potential for major repairs in the future.

Seal coating serves not only as a protectant, but also provides an attractive black coating to your driveway or parking lot, giving it the look of a newly paved surface.
