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
