Prediction of structural damages of road pavement using GPR

A new methodology has been proposed to extract the hydraulic permittivity fields in sub-asphalt structural layers and soils from the moisture maps observed with GPR. It is effective at diagnosing the presence of clay or cohesive soil that compromises the bearing capacity of sub-base and induces damage on the road. The numerical algorithm has been yet discussed in the 11th International Conference on Ground Penetrating Radar [5]. Here some experimental confirms have been presented.
