Mechanical and Shrinkage Properties of Base Materials of Fly Ash and Cement Stsbilized Crushed Rock

Through the study using part of fly ash to replace equal cement on the base of cement stabilized crushed rock,the mechanical and shrinkage properties of the fly ash and cement corporate stabilized crushed rock are tested.The results show that cement replaced by fly ash is practical,and not only has economical effect,but also has some technical advantages.Even if the compressive and splitting tensile strength as well as elastic modulus decreases with improving fly ash percent,the effect of fly ash on compressive strength is little in a certain range but shrinkage reduced evidently.
