Railroad track modulus estimation using ground penetrating radar (GPR) measurements

Last updated on 02 September 2014 3:45

Almost one-third of all railroad accidents are caused by track defects. Track failures resulting from weak strength and buckling cause many of the accidents. One parameter that greatly affects track performance and safety is the track vertical modulus, which is a measure of the vertical stiffness of the rail foundation.
