The article presents the results of GPR investigation of the damaged sections of the road surface obtained during the laboratory testing. In the modeling process, there were recreated three different damaged zones: a zone of suffusion, a closed crack zone, and a crack transforming into the cavern zone. Examples of amplitude analysis of radargrams are demonstrated, search images are revealed which are inherent for the modeled destruction zones. In order to improve the efficiency of the destruction localization, there were built up maps of the amplitude distribution of the reflected electromagnetic signal. The result of GPR survey of the highway section within an urban development is described.
