Cement Concrete Pavement Composite Pavement Reconstruction Inhibit The Contraction Glass Fiber Geogrid

Glass Fiber Geogrid Introduction

Fiberglass geogrid is a kind of new geosynthetics for the reinforcement of road surface and rodbed.This product is made of fiberglass filament by woving machine imported abroad.After coated,it has featurers of alkali-resistance.This geogrid is mainly used in new road,soft road surface to enlarge the loading capacity and road maintainence to prevent the road crackle.

Glass Fiber Geogrid Specification

Glass Fiber Geogrid Features:

1. G tensile strength, low elongation - glass fiber geogrid is made of glass fiber, has a very g resistance to deformation, fracture elongation is less than 3%.
2. No long-term creep - as a reinforcing material, it has the ability to resist deformation under long-term load, i.e. creep resistance is very important. Glass fiber will not creep, which ensures that the product can maintain its performance for a long time.
3. Thermal stability: the melting temperature of glass fiber is above 1000 ℃, which ensures the thermal stability of glass fiber geogrid in paving operation.
4. Compatibility with asphalt mixture - the coating material of glass fiber geogrid in the post-treatment process is designed for asphalt mixture, each fiber is fully coated, which has good compatibility with asphalt, so as to ensure that the glass fiber geogrid in the asphalt layer will not be isolated from the asphalt mixture, but firmly combined.
5. Physical and chemical stability - after coating with special post-treatment agent, the glass fiber geogrid can resist all kinds of physical wear and chemical erosion, as well as biological erosion and climate change, ensuring its performance is not affected.
6. Because the glass fiber geogrid is a network structure, the aggregate in asphalt concrete can run through it, thus forming mechanical interlocking. This limit hinders the movement of aggregate, which makes asphalt mixture achieve better compaction state, better bell bearing capacity, better load transfer performance and smaller deformation under load.

Glass Fiber Geogrid Application:

1,Disposal of landfill,

2,Roadbed enhancement of highways,

3,railways and airports,
4,Reinforcement of mines and tunnels
