| Abstract: | In allusion to the scour resistance of cement fly-ash stabilized macadame, stabilized macadame, lime fly-ash gravel with different mixture radio, the contrast tests through. According to the results of tests, the optimal mixture radio of subgrade materials lime fly-ash are carried can be referred in designing the base course which can adapt the high strength of subgrade and has less crack and good scour resistance in southern areas with heavy traffic. |
