Abstract

Treating soil compaction is the key to its construction quality control, but now its compaction evaluating indicator does not match with design specification in China, which makes design and construction control having disjointed phenomenon. Based on the deflections tested by FWD, the relationship between pavement surface deflections and its structure deformation is analyzed in this paper, and the result shows that the compaction of the load layer can be reflected by three deflections which are most close to the bearing plate. Combining with the field tests, the relationship between the deflections and compaction is further studied, and good correlation between deflection basin index and compaction is found, so the evaluating index of compaction is put forward. Thus, the layering monitor of construction quality is tried to develop in roller compaction process, which provides an idea for the soil quality control.
