Laboratory Test Method for Dynamic Rebound Modulus of Subgrade Red Clay in Moist-Heat Area

Ten representative expressway pavement structures in the southern humid area were investigated, and then the stress state of subgrade soil under the pavement structure was calculated and analyzed by multi-layer elastic system theory. Based on the latest research results at home and abroad, combined with the stress and physical properties of subgrade soils in south moist and heat area, the laboratory test method for dynamic rebound modulus of subgrade soil in this area was determined.
