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.
為將水泥粉煤灰穩定煤矸石更好地應用到道路基層,需對其級配進行優化設計.文中以混閤料形成骨架密實結構為目標進行粗集料級配設計,以k法為基本理論進行細集料級配設計,最後綜閤粗集料與水泥粉煤灰砂漿配閤比例,提齣水泥粉煤灰穩定煤矸石總的級配設計麯線,具有一定的普遍性和實用價值.

of roads, aggregate designed overall For it i gra the better application of cement-fly ash stabilized coal gangue to the base course sneededtooptimize the design of their grading. First, we designed the coarse ding for obtaining mixture formation closegrained skeleton structure, then fine aggregate grading with the basic theory of k law. At last, we made the grading design curves of cement-fly ash stabilized coal gangue through comprehensively comparing the ratioes of coarse aggregate and cement-fly ash mortar. The curves were of certain universality and practical value
