Experiment research of lime-fly ash Soil's dynamics characteristics

Nearly for more than ten years,lime-fly ash soil has generally made the road subbase and basic unit due to its low construction cost,advantageous to the environmental protection,the long-term higher strength characteristic.the dynamic triaxial tests for different mixing proportions of soil and lime-fly ash soils to study lime-fly ash soils content influence on the dynamic parameter;and several kinds of mixing proportions test results are given for comparison and reference.The test results indicate that the lime-fly ash soil contents of larger than 40%,is not suitable otherwise the significance is not big,and is uneconomical.
