What role did geotextile play on the asphalt pavement?

Geotextile has strong heat resistance and huge cold resistance, high tensile strength, good elasticity, low expansion coefficient, strong wear resistance, excellent tear strength, and high chemical stability. Geotextiles of various specifications have been widely used in asphalt highway construction and asphalt pavement repair. As an indispensable material for asphalt pavement, this product can prevent cracks on the road surface due to shrinkage at low temperatures, can change the structural stress distribution of the road surface, prevent the expansion of reflective cracks, and can also reduce rutting and rolling marks. After the surface chemical treatment of this polypropylene nonwoven geotextile for sale, the adhesion between the fiber and the asphalt is enhanced, so that it can contact the asphalt mixture at a high temperature of 160 ℃ without cracking and warpage. It has excellent construction performance, can prolong the service life of the highway, and can relatively reduce the thickness of the pavement structural layer, so as to achieve the purpose of reducing the cost of highway construction.
