结合SMA混合料及矿物纤维的特点,根据所用原材料进行了不同油石比及不同矿物纤维掺量下的性能比对试验,分析得出最佳矿物纤维掺量及沥青用量,为矿物纤维SMA设计提供参考。
According to the characteristics of SMA mixture and mineral fiber, the performance comparison experiments of different mineral ratio and different mineral fiber content were conducted according to the raw materials used, and the best mineral fiber content and asphalt content were obtained, which could provide references for SMA design of mineral fiber .
