Abstract：Aggregate gradation and cement content are important factors that affect the porousness,the permeability coefficient, the strength and modulus of cement treated crushed stone. Samples of five open-graded aggregates, and four levels of cement content were tested in"drainage-lag"permeameter developed by Barber and Sawyer, and then the samples were tested in compressive strength and modulus of resilience. The relations between material composition and performance of cement treated crushed stone were discussed and the regression equations were developed on the basis of laboratory tests and stepwise regression analysis. These results provide valuable guide for the mix design of cement treated crushed stone.
