Based on some studies at home and abroad, with analysis on water damage in pavement, design method of subsurface drainage system is discussed in this paper, and the major technical performance indexes is introduced too. Through much theoretical analysis of laboratory experiments, mechanism properties and composition design method of porous cement-treated macadam is obtained.

The result notes that dynamic triaxial test preferably simulate the actual stress state of grading macadam, and Uzan model which considers the shear performance of material can better reflect stress states of grading macadam. Regression coefficients of the model obviously present nonlinear characteristic with moisture changed, and to further influence dynamic resilient module.More the module is larger, more diminishing rate of maximum tensile stress on pavement Bottom is smaller. To enhance draining function and strength, the gradation should been rigid controlled, and which the content of less than 0.075mm is controlled between 5～7％ and spring-back is controlled between200~300MPa are appropriate.
