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.

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.
