【 摘 要 】

Asphalt stabilized drainage base has good drainage performance, can effectively rule out the water in pavement structure, reduce the occurrence of water damage, and maintain good pavement performance. Based on the mechanical analysis of the affect of asphalt stabilized permeable base on the inhibition of reflection crack, using the finite element software to simulate the stress characteristics of the asphalt and to do the mechanical analysis of asphalt pavement cracks at the grass-roots level to the pavement after stretching process, by comparing the pavement crack tip stress intensity factor of original pavement structure and set up the ATPB layer, respectively, to study the effect of asphalt stabilized permeable base on inhibition of reflection cracking.
