Geocomposites and Asphalt Paving

Release time：2025-11-02    Click：74

　　While reflective cracks are observed at the road’s surface, they are generally not caused by traffic. Over time, asphalt roads can be exposed to subsidence or bending, and the cracks eventually make their way to the surface. Once the cracks are exposed they allow water into the pavement. Moisture in the subgrade weakens the pavement structure and causes spalling (separation and loss of material) at the crack, bums, and wear. Left untreated, the road will eventually deteriorate.

　　To avoid the formation of reflective cracks, contractors place geocomposites, such as grid-reinforced bituminous membranes, during paving in between coating layers. These products provide both reinforcement and crack prevention.
