To attain the same strength grade, the content of cement in cement fly-ash stabilized hoggin has reduced by 0.5~1% comparing with cement stabilized hoggin. This material has a capability of adapting with different aggregate's gradation and the 4.75mm passing rate can reduce to 30%. Through the studying about the mechanical property of cement fly-ash stabilized hoggin, this manuscript discover that the material has good strength growing performance that its 90d strength growing rate is 385% and its splitting strength that the 7d splitting strength is 0.347MPa and the 90d splitting strength is 0.700MPa accord with requirement in the norm.
