Asphalt geocomposites are geocomposites constructed by a high-tenacity fiberglass grid, a lightweight nonwoven geotextile and bitumen coating which can provide a good bonding property with asphalt layers.
The fiberglass geogrids offer high strength, high modulus and high temperature resistance for performing high reinforcement ability, and raise the resistance of fiberglass geocomposites against the damages from installation. Moreover, the nonwoven geotextiles increase the liquid asphalt retention capacity of the product. With the geocomposites to reinforce asphalt layers, the pavements can extend their service life and reduce the occurrence rate of reflective cracking under cyclic traffic load. Therefore, asphalt geocomposite is a highly effective and economical solution for road rehabilitation.
Ashpalt Geocomposite Features
• Very Low elongation and high tensile modulus
