Fiberglass Pavement geoComposites
- Fiberglass Geogrid combines With Nonwoven Geotextile Impregnated By Bitumen is an Asphalt Reinforcement geoComposite that fiberglass geogrid with light weight Polyester Spunbond Nonwoven Fabric .
- They are stitcked together and coated by bitumen to strengthen the bond with the asphalt layers . The asphalt layer to increase the tensile strength to prevent road surface crack caused by foundation crack reflection.
- The chemistry stability is good, the hot-stability is good, anti-weary dehiscence, anti-low temperature shrinkage crack, postponement reduction reflection crack.
Product Function
- It can widely apply in the water conservation, the municipal administration, the building, the transportation, the subway, the tunnel, the environmental protection and so on.
Geocomposites and Asphalt Paving
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.
