| Abstract: | Considering of four kinds of subgrade soil, dynamic resilience modulus E0 of every soil are tested by PF- WD in different compactness. And CBR of every soil are tested by laboratory experiment at the same time. The variation law of Eo and CBR following with compactness are analyzed. Correlativity formulae between Eo and CBR of every soil before and after soaking are proposed. The study conducted in this paper provides reference for construction. |
