초록
RPBT (Ev2) has been used mostly in railway construction site according to QC requirement. However, it takes a lot of time to perform RPBT test, and also it needs heavy truck to get reaction force for loading plate. The stress condition of compacted soil underneath the loading plate of RPBT is not clearly understood yet. Thus, for replacing the RPBT purpose, LWDT is proposed for standard DOC control of compacted subgrade soil in the field. A new QC guideline for using LWDT is going to be provided after analyzing efficiency and economic feasibility analysis of using LWDT in this study.
