Conservation road cloth (1) is widely used in asphalt pavement, concrete pavement and subgrade enhancement. Whether rigid and flexible pavement all suitable roads, compared with the traditional road to reduce costs, extend the life of the road to prevent reflection cracks. (2) the thickness of the product is appropriate, easy to combine with the asphalt pavement, after the formation of sticky layer of oil combined with the isolation layer, a waterproof and insulation. (3) light weight, high strength. Tensile strength were ≥8 KN / m, elongation of 40 to 60%, fully meet JTJ / T019-98 "highway geosynthetic stress technical specifications" in the technical requirements of the geotextile. (4) surface roughness, easy to slide. When laying the surface after the special treatment the rough side up, increasing the friction coefficient of the surface layer increases the binding force to prevent the construction of the wheel is rolled, vandalism, and inhibited the vehicle, paver appears on the cloth skidding . (5) UV, freezing cold, resistance to chemical corrosion and biological destruction capability. (6) easy construction, good application effect. General geotextile filaments easily be brought up vehicle tires, causing hanging wire, even when serious is rolled, causing the displacement of geotextile and structural damage
