Orthogonal Experimental Design about Optimum Gradation of Cement Stabilized Crushed Stone

The main factors influencing strength of cement stabilized crushed stone are deduced when considering dry shrinkage performance.Orthogonal experimental method is adopted based on these factors,obtaining 9 gradation through 3 points controlled power function and relationship among every factor and every index.Finally the optimum gradation of cement stabilized crushed stone is calculated according to the experimental index of each gradation.This is design method of inorganic binder stabilized crushed stone material.
