prevent reflection cracks on asphalt pavement
Reflective cracking is a common disease in asphalt pavement. Reflective cracks destroy the integrity of the road surface and affect the appearance of the road surface. Water enters the base layer through the cracks to accelerate the destruction of the asphalt pavement and seriously affect the performance of the asphalt pavement.
ZTS stress absorbing layer between the cracked structure layer and the asphalt overlay is an effective measure to prevent reflection cracks. It is an asphalt mixture with strong adhesion, impermeability, and good interface bonding performance, can deform with the deformation of the base layer, and has excellent self-healing ability.
ZTA-VE additive are a new type of composite asphalt additive developed by Beijing Zhongtian Road Tech Co. Ltd. It integrates the technical characteristics of high viscosity, high elasticity, wide temperature range, and warm mixing to improve the crack resistance and fatigue resistance of road materials, reduce the difficulty of road construction, energy saving and environmental protection.
