ICMV(Intelligent Compaction Measurement Value) is a method capable of managing the ground hardness in real time in the entire construction area, and is one of the ICT techniques for which further utilization is desired. On the other hand, it is a problem that ICMV changes the value to be evaluated if the soil quality of the embankment material. In order to clarify these effects, the authors conducted a compaction test. Here, the correlation between ICMV and soil characteristics of water content and dry density and strength characteristics obtained by small FWD(Portable Falling Weight Deflection Test) was analyzed.
