In the process of "white and black" reconstruction, a thin stress absorbing layer on the rigid base can effectively prevent the appearance of reflection cracks. The traditional geotextile stress layer has a certain waterproof ability, but when the spreading temperature of the hot asphalt mixture exceeds 160℃, the geotextile has poor strength and creep resistance, so it can not play the reinforced anti-cracking effect. Glass fiber grating and asphalt mixture can form the effect of extrusion. Read More
