| Abstract: | By the experimental research on the unconfined compressive strength, splitting tensile strength and shrinkage coefficient of the cement and fly-ash stabilized crushedstones, the strength and shrinkage characteristics of the variation are analyzed. Appropriate blending ratio of fly ash is recommended and the engineering is tested and verified, which can provide basic data for the industrial standards and the application promotion. |
