DAT与SA温拌排水沥青混合料路用性能对比
Pavement Performance Comparison Between DAT and SA Warm Porous Asphalt Mixture
摘要
Abstract
This paper mainly discusses effects of Sasobit(SA)and DAT on the pavement performance of po-rous asphalt mixture. Firstly,the optimum mixture ratio of hot porous asphalt mixture is decided through Mar-shall test. Then,pavement performance tests are conducted in SA and DAT porous asphalt mixture. Tests show that SA and DAT additives can produce appropriate temperature drop range with 155℃as the suitable compac-tion temperature for warm porous asphalt mixture. Besides,the anti-rutting performance of the former is obvi-ously better,while the latter low temperature performance is better,though water stability of them is similar. The paper proposes a new technology for green road construction by using SA and DAT additives in warm po-rous asphalt mixture with SA as a preferable additive.关键词
