摘要
针对高性能沥青Superpave混合料的路用性能进行研究。选用我国高速Sup-16及Sup-25两种高性能沥青混合料,对两种沥青混合料在不同级配下的高温稳定性、低温抗裂性、水稳定性能及抗疲劳性能进行试验分析。验证了高性能沥青混合料路用性能的优越性,并研究了Super-pave禁区和控制点存在的合理性。
The high performance asphalt pavements technology, which is called the Superpave technology, is one of the results of American Strategic Highway Research Project （SHRP）. This paper researched the pavement performance of Superpave asphalt mixture. High temperature stability, crack resistance at low temperature, moisture stability and fatigue resistance of Sup-16 and Sup-25 at different gradation were analyzed in the paper. The superiority of Superpave asphalt mixture was verified, and the rationality of forbidden zone and reference point was also analyzed by lots of laboratory experiments.
