In this paper we propose a novel inspection method based on Ground Penetrating Radar techniques to predict pumping and reduce the risk on safety.

Abstract

In this paper we propose a novel inspection method based on Ground Penetrating Radar techniques to predict pumping and reduce the risk on safety. Experimental layouts are developed to measure the clay content in sub-grade/sub-base compacted soils. Typical road material is analyzed using two different GPR systems: three types of soils are adequately compacted in electrically and hydraulically isolated boxes. Bentonite clay is gradually added from 2% to 25% by weight. Signals are analyzed in both time and frequency domains, and the reliability of results is respectively validated by the electromagnetic and the Rayleigh scattering theory showing promising correlations.
