Study on the testing method of lime-ash strength

Lime-ash is semi-rigid material.lt widely used in the construction of the highway subbase.Studying on engeering characteristic of lime-ash is mature.but,it always separately considered static force and motive power on studying the characteristic of lime-ash.lt is different from practical situation.So, loading motive power in the model first,then carrying out common triaxial test.The testing method is more similar with practical situation. The testing can be used to study the strength of lime-ash .The result of testing can be used to compare the index of shear strength of loading motive power before and after. Practical designing can rely the analysis result.
