| 摘 要： | 为将水泥粉煤灰稳定煤矸石更好地应用到道路基层，需对其级配进行优化设计．文中以混合料形成骨架密实结构为目标进行粗集料级配设计，以k法为基本理论进行细集料级配设计，最后综合粗集料与水泥粉煤灰砂浆配合比例，提出水泥粉煤灰稳定煤矸石总的级配设计曲线，具有一定的普遍性和实用价值．

| Abstract: | For better application of cement-fly ash stabilized coal gangue to the base course of roads,it is needed to optimize the design of their grading.First,we designed the coarse aggregate grading for obtaining mixture formation close-grained skeleton structure,then designed the fine aggregate grading with the basic theory of k law.At last,we made the overall grading design curves of cement-fly ash stabilized coal gangue through comprehensively comparing the ratioes of coarse aggregate and cement-fly ash mortar.... |
