Abstract:
Ground Penetrating Radar (GPR) has become an
increasingly attractive method for the engineering community, in
particularfor shallow high-resolution applications such as railway
trackbed evaluation. It is a non-destructive smart sensing technique,
which can be applied dynamically to achieve a continuous profile of
the trackbed structure. Due to recent hardware and software
improvements, real time cursory analysis can be performed in the
field. Based on collected field data, the present paper investigates
the applicability of the GPR smart sensor system in terms of the
railways trackbed assessment and concludes on the capability ofthe
GPR sensing technique to assess adequately the ballast quality and
the trackbedformation.
Keywords- GPR, railways trackbed, ballast.
