Abstract

Beijing West Chang’an Avenue was re-overlaid in 2014 to improve its service condition due to serious reflection cracks . The existed structure of pavement is a combination of 8~10 cm bituminous surface based on cement concrete layer. In this case study, the cracked bituminous layers were removed and a stress absorbing layer was applied to improve the cohesion between road base and surface layer. A high temperature and traffic loading standard (70 , 1.0MPa) was adopted in according to the real project conditions. A series of performance laboratory test was conducted to optimize materials design and evaluate the characteristic of the materials. The laboratory test results shown that the modified bitumen has a excellent performance with higher resistance of fatigue and deformation. This project has been open to traffic for nearly one year and the stress absorbing layer were approved to effective reduce the reflection cracks and moisture damage of pavement structure in the light of the satisfactory pavement service indexes.
