| Abstract: | Through the comhination of library tests and construction,the paper researched the mechanical performances of rubber-asphalt SMA-16 and AC-20 ,developed a new method of rubber-asphalt＋gap graded gravel binder layer between upper-layer and middle-layer , and inspected its functions by tests, calculated stresses at the bottom of all layers with BISAR program, hereby Optimized asphalt pavementdesign was finished in Wu-Ma expressway. It is showed that optimized rubber-asphalt pavement design can improve the ability of anti-crack and resistance to water damage,reduce engineering costs. |
