Effect Of Fiberglass Geogrid On Pavement

- Dec 20, 2017 -

In some aging cement pavement with a layer of asphalt, which can enhance the use of pavement performance, but it does not strengthen the load-bearing function of the road, the overall road load is reflected in the roadbed, so add a layer of asphalt concrete pavement is still the main body. The asphalt overlay on some aging asphalt pavement is different, and the asphalt overlay will be loaded with the aging asphalt pavement. Therefore, the asphalt surface on the asphalt overlay, in addition to some cracks, but also because of long-term load and fatigue cracking.

We have carried on the stress analysis to the asphalt road surface load condition: Because the asphalt cover layer's strength is softer, therefore when it receives the relatively big load, the bituminous pavement table will occur the sinking phenomenon. Glass fiber Geogrid has high strength, low elongation, high temperature resistance, high modulus, light weight, good toughness, corrosion resistance, long life and other characteristics, can be widely used in the old cement road surface, airport runway maintenance, dams, river banks, slope protection, road and bridge pavement enhancement treatment and other engineering fields.
