High tenacity polyester fabric is a high-performance, high-standard, high-specification product produced by newer technology, higher technology, and formula to meet the needs of national key projects such as highways, road construction, old road reconstruction, water conservancy projects, and railway construction. The product. It overcomes the defects of the original material, improves the tensile strength and creep resistance of the high-performance polyester fabric, and improves the basic properties and technical indicators such as longitudinal and transverse tensile strength. It obviously improves its low-temperature crack resistance, fatigue resistance, and anti-reflection, thus prolonging the service life of the pavement. The high-performance polyester cloth has a smooth surface, more uniform thickness, disappears transparency, stronger compatibility with asphalt mixture, and a more obvious use effect. Laying a layer of high-performance polyester cloth between the lower layer and the surface layer of the asphalt pavement structure can reduce and delay the cracking of the pavement caused by the overlap of the old and new pavement and the semi-rigid base, and prevent damage to the base caused by moisture intrusion. It is used in reconstruction projects of new and expanded roads; reinforcement treatment of foundation roads and treatment of shrinkage cracks in semi-rigid foundations; reconstruction, expansion, and asphalt surface layer projects of old cement pavements; maintenance and repair of old asphalt roads. Repair works such as pavement cracks caused by old foundation crack reflection and uplift. Provide the reinforcement of the base layer for the construction of airport runways, roads, bridges, railways, and other projects.
(1) Compared with ordinary anti-crack fabric, high-tenacity polyester fabric has lower elongation and higher tensile strength, which ensures a longer use effect of the product.
(2) The chemical properties of high-tenacity polyester fabric are stable, and after updating the process and formula, it can prevent various chemical erosion and climate change and has a wider range of applications.
(3) The high-tenacity polyester fabric will not be damaged below 205 degrees Celsius, and the optimal temperature of the asphalt is controlled at 55-168 degrees Celsius, so that its stability and performance will not be affected.
(4) High-tenacity polyester fabric has good compatibility, which can form an effective waterproof layer. Even if there are small cracks in the surface layer, it can basically prevent the surface water from seeping down and prevent the road base material from being protected from water. erosion.
