Abstract:

Six commercial ground penetrating radar (GPR) ; systems were evaluated to determine the state-of-the-art of GPR technologies for railroad track ; substructure inspection. ; Phase 1 evaluated GPR ballast inspection ; techniques by performing testing at the ; Transportation Technology Center (TTC) in ; Pueblo, CO. The evaluation was conducted at ; the Facility for Accelerated Service Testing ; (FAST) on the High Tonnage Loop (HTL). ; Investigators from TTC compared the ballast ; fouling and layer depth outputs of different GPR ; systems. The outputs of the different systems ; were compared with one another and with other ; known conditions. Also, a moisture sensitivity ; test was performed to confirm the ability of GPR ; to sense relative changes in moisture.
