【 摘 要 】

Stability of roadbed can be effectively improved when the roadbed filler is mixed with lime content, while the physical properties of the limestone soil are very complicated. The variation characteristics of dry density, optimum moisture content and resilient modulus are studied with laboratory experiment. Firstly, set three group weathered mudstone soil with different lime content (4 %, 6 %, 8 %), then compare with the mixed soil of clay and sand, at last, to do the compaction test of each group. The research shows that engineering properties of the strong weathered mudstone is effectively improved. The finite element shows that the settlement and stability of roadbed is obviously improved after replacement with lime soil.
