Abstract:

The overall aim of this project was to relate Ground Penetrating Radar (GPR) to ballast fouling. The 10-year old University of Edinburgh full-scale trackbed was revisited and the fouling of the ballast was recalibrated following environmental changes, using the Ionescu fouling index. A series of GPR experiments were undertaken on the trackbed using a range of bowtie antennas from 500MHz to 2.6GHz. Scatter analyses of the GPR waveforms included area analyses, axis crossing analyses and inflexion point analyses. When predicting Fouling Index, a correlation coefficient greater than 0.9 was obtained by using a 500 MHz bowtie antenna in the parallel orientation in conjunction with a scan area analysis. This paper will outline the recent work of other researchers and the detailed experimental program at the University of Edinburgh.
