GPR quality control of building and technical state of exploited autoroads in conditions of permafrost

Represented results of GPR approbation of road filling, exposure of drainage zones and watering of geological foundation of autoroads of Yakutia. On the basis of analysis of kinetic characteristics of GPR signals there were defined zones of alteration of cryogenic subsoil condition. Here we offered methodic of noncontact shooting on the assigned profiles at the rate of movement of auto-laboratory.
