Research on correlation between dynamic resilient modulus and CBR of coarse-grained chlorine saline soil [PDF]

Scientific Reports
A large area of coarse-grained saline soil is distributed in saline soil areas, and chlorine saline soil with a high salt content is a typical representative. The dynamic resilient modulus was accurately predicted using the California-bearing ratio (CBR)
