High speed railway ballast characterisation using ground penetrating radar

This paper demonstrates how high speed (80 km/h) GPR is being used operationally in Australia to classify ballast and drainage conditions of actively used railway tracks. By providing this information on an ongoing basis, proactive rather than reactive track maintenance is possible by railway maintenance personnel. GPR scanning has been implemented to classify the operational parameters used by track maintenance personnel, such as: Requirement for maintenance or replacement of ballast; Clay content of ballast; Ballast volumes and Optimal setup configuration for ballast cleaning machines to remediate specific track. The paper also shows how GPR and maintenance records can be combined to enable strategies for optimizing maintenance programmes and to qualitatively assess ballast degradation rates.
