composite geogrid can be used in the reinforcememt of the roadbed. [APPLICATION](1) Road surface reinforcement of road,railway and airport road;(2) Maintenance,reconstruction and widening of old road surface(asphaltum road or cement concrete road).(3) Reinforcement of soft soil roadbed,irrigation channels and water dams. [PROPERTIES(1) High tensile strength in both the warp and weft directions;(2) Low elongation;(3) Excellent temperature range;(4) Good anti-age and alkali-resistance;(5) Reduce construction cost, extend service life of road and prevent deflection cracks. [TECHNICAL DATA] Tensile strength:50KNX50KN+25G PP,80X80KN+25G PP,100X100KN+25G PP,120x120KN+25G PP with one side Elongation:<4% Width:1m-6m Roll length:50m or 100m
