SPR-4951: Development of a Ground Penetrating Radar Based Testing Program for Mechanically Stabilized Earth Walls

INDOT Research & Development engineers have identified GPR as a potential method for assessing the extent of voids in MSE walls. However, current GPR configurations cannot be used for scanning vertical surfaces. Therefore, GPR testing equipment specially designed for MSE wall void detection must be built. This project aims to produce and validate a GPR test system capable of locating voids in MSE walls.
