摘要
通过沥青混合料的马歇尔指标及路用性能指标和现有的设计方法,对Superpave-19沥青混合料进行了配合比设计,并进行了室内试验研究和对试验段检测。研究结果表明:Superpave-19沥青混合料的最佳沥青用量为4.4%,具有较好的高温稳定性和低温抗裂性,路用性能良好。
Based on the Marshall index and road performance index of asphalt mixture and the existing design method,the mix ratio design of Superpave-19 asphalt mixture was carried out,and then the indoor test research and the road performance were tested on site.The research results show that the optimal asphalt dosage of Superpave-19 asphalt mixture is 4.4%,which has good high temperature stability and low temperature crack resistance,and good road performance.
