Research on prediction model of dynamic resilient modulus of subgrade soil based on matric suction

Matric suctions of test specimens were surveyed by using the filter paper method,and parameters of soil-water characteristic curve(SWCC) equations were obtained by using regression analysis.For the sake of investigating factors which affect subgrade dynamic resilient modulus(MR) and their lows,a series of resilient modulus tests were carried out with repeated load triaxial tests on reconstituted cylindrical specimens.Based on the corresponding relationship between moisture content and matric suc...
