Road maintenance geotextile (polyester fabric geotextile, non-woven fabric geotextile), also known as geotextile, is a material composed of chemical fibers.
Road maintenance geotextile (polyester fabric geotextile, non-woven fabric geotextile), also known as geotextile, is a material composed of chemical fibers that undergo water absorption geotextile testing through needle tying or weaving. The product is in the form of cloth, with a general spacing of 4-6 meters and a length of 50-100m. In brief, geotextiles are divided into woven geotextiles and non-woven geotextiles.
The geotextile for road maintenance mainly has the following characteristics
1. Pavement maintenance geotextile is widely used for the improvement of asphalt pavement, concrete pavement, and foundation. Both mandatory and soft road surfaces can be used, which can reduce engineering costs, increase service life, and avoid reflective surface cracks compared to traditional roads.
2. The pavement maintenance geotextile is suitable for thin and thick thickness, and is easy to blend with asphalt pavement. After blending with adhesive layer oil, it produces an isolation layer, which has moisture-proof and thermal insulation effects.
3. Road maintenance geotextile has light quality and high toughness. The compressive strength is ≥ 8 KN/m, and the tensile strength is 40-60%, fully meeting the technical standards for geotextiles in JTJ/T019-98 "Technical Specification for Stress of Highway Geosynthetic Materials".
4. The surface of road maintenance geotextile is not smooth and not easy to roll. When paving, the surface should be treated with a rough surface facing downwards to increase friction resistance, improve overall surface adhesion, and avoid being rolled over or damaged by wheels during the construction process. Together, it can suppress the deviation problem of vehicles and asphalt pavers on the cloth.
5. The pavement maintenance geotextile has the ability to block ultraviolet rays, resist low temperature freezing, resist corrosion, and resist biological damage.
6. The pavement maintenance geotextile is easy to construct and has good application effects. The fibers of general geotextile are easily driven by vehicle tires, causing wire hanging and even being rolled over in severe cases, resulting in displacement and structural damage to the geotextile.
