| Abstract: | This paper applied the gray system theory to study the influencing factors of the mechanics performances for the lime flying-ash broken stone mixture, and acquired the influencing-level order of the factors of gradation, coarse, fine aggregate and binders content to the lime fly-ash broken stone mixture's compressive strength, split strength, tension-bending strength and other modules. This method can provide a type of scientific evaluating way for the optimization design of the base course mixture. |
