摘要
介绍了煤矸石做道路基层材料的应用情况 ,从煤矸石混合料具有的无侧限饱水抗压强度、抗弯拉强度、冻融稳定性、低温收缩性等方面阐述了煤矸石能满足多种等级公路的规范要求 ,指出其具有广泛的推广价值。
The application situation of coal gangue used as road base material is firstly introduced. The characteristic of coal gangue that can meet demand of various grades road standard is clarified from advantages of coal gangue such as unconfined saturation water compressive strength, bending strength, tension strength, freeze-thaw stability, low shrinkage ratio and so on.Finally the writer points out that coal gangue are worth being widely spread.
