| Abstract: | Studying the feasibility of using graphite scoria as filling material of expressway. Based on the testing analysis of mechanics performance of graphite scoria and the stability of water and temperature and compressive strength of the material after the stabilization of cement, the paper discusses the feasibility of cement stabilized graphite scoria, and indicates a criteria for compaction control of construction of using the cement stabilized graphite scoria for the subbase course of express highway, and finally suggests a proper dose of 6% for cement. |
| Keywords: | graphite scoria base-course stability of water and temperature compressive strength |
