Trackside - Ballast Condition Surveys
FromZETICA
Rail track defects are often caused by poor ballast conditions. Zetica surveys provide objective information on track ballast condition that helps cut the costs of maintenance and renewals. Zetica scans track ballast condition at high speed using train-mounted multichannel GPR equipment linked to positioning systems and integrated with the results of track geometry surveys.
