Anti-rutting Performance of Asphalt Pavement Modified by Rock Asphalt
The modification mechanism of natural rock asphalt modifier was analyzed. The high-temperature performance of modified asphalt concrete with natural rock asphalt was studied based on rutting test and dynamic creep test, and the anti-rutting performance of asphalt pavement structure affected by rock asphalt modifier was calculated with the finite software ANSYS. The results indicate that (1) the module of asphalt concrete, the dynamic stability and the creep module of asphalt mixture can be enhanced greatly and the high temperature performance of asphalt mixture can be strengthened obviously by using rock asphalt modifier; (2) the anti-rutting ability of rock asphalt modified asphalt pavement structure can increase 20% compared with that of the common asphalt pavement structure.
