Abstract

For the estimation of the behaviors of unpaved roads under cyclic wheel loads, investigation of the mechanical properties with depth is required. In this study, the dynamic cone penetrometer (DCP) and crosshole-type dynamic cone penetrometer (CDP) are applied to an unpaved road to characterize both the strength and stiffness along the depth. The strength and stiffness of the unpaved road subjected to cyclic wheel loads are characterized by the penetration index (DCPI) and shear wave velocity (Vs), respectively. Experimental results clearly show the changes in strength and stiffness increase due to the wheel loads. This study demonstrates that the DCP and CDP may be effectively used for subgrade assessments of unpaved roads with depth.
