Evaluating The Influence Of Breakdown Fouling And Moisture Content On Mechanical And Electromagnetic Properties Of Ballasted Railroad Track, Hamed Faghihi Kashani

Doctoral Dissertations

A complete study was performed to develop correlations between electromagnetic and mechanical properties of ballast. These correlations can be used to predict the deformation properties of ballast and also its dynamic behavior under heavy axle load in different fouling and moisture conditions by GPR survey. By developing this technique and performing similar tests on different types of ballast and fouling materials, a criterion can be developed to detect the railroad high risk areas and predict the engineering properties of ballast by GPR surveys. This study was performed on granite ballast and breakdown fouling and has three phases: performing GPR survey …
