摘要
以十天高速陕西境汉中—略阳段项目为依托,从原材料选用、沥青混合料的矿料级配设计、SMA混合料最佳油石比的确定、最佳油石比修正以及SMA混合料性能验证等方面对SMA-13沥青混合料的目标配合比设计进行了研究。结果表明:所设计的SMA-13沥青混合料各项性能均符合要求。
Based on the project of Hanzhong-Lueyang section of Shitian Expressway, the target mix proportion design of SMA-13 asphalt mixture was studied through raw material selection, mineral aggregate gradation de- sign, determination and correction of optimal asphalt content, and performance validation of SMA mixture. The results show that the performance of SMA-13 asphalt mixture can meet the requirements.
