What are the characteristics of geotextile pavement maintenance?

　　ntroduction to geotextile:

　　1. Widely used for strengthening asphalt pavement, cement concrete pavement, and roadbed. Both hard and flexible road surfaces are suitable, which can reduce cost, extend service life, and prevent road reflection cracks compared to traditional road surfaces.

　　2. The product has a suitable thickness and is easy to combine with asphalt pavement. After combining with adhesive layer oil, it forms an isolation layer and has waterproof and thermal insulation effects.

　　3. Lightweight and high-strength. The tensile strength is ≥ 8 KN/m, and the elongation is 40-60%, fully meeting the technical requirements for geotextiles in JTJ/T019-98 "Technical Specification for Stress of Highway Geosynthetic Materials".

　　4. The surface is rough and not easy to slide. When laying, the rough side of the surface after special treatment should be facing upwards to increase the friction coefficient, increase the adhesion of the surface layer, prevent it from being rolled up or damaged by the wheels during construction, and at the same time, prevent vehicles and pavers from slipping on the cloth.

　　5. It has the ability to resist ultraviolet radiation, cold freezing, chemical corrosion, and biological damage.

　　6. Easy to construct and effective in application. Not easily picked up by vehicle tires, ensuring good construction results.
