Abstract

Summary

Comprehensive studies of the internal structure of road structures by the geo-radar "OKO-3" were performed on the existing road network with the evaluation of the elastic modulus on the surface of the road structure using the FWD dynamic load setting. Identified by the received radarograms on sections of roads violations at the boundaries of the contact layers in road structures. The impact of violations at the boundaries of the contact layers of the road structure on the strength characteristics of the road is evaluated. Analysis of the radarograms on the road sections showed that gaps, absence and blurring of the in-phase lines at the boundaries of the layers indicate a decrease in strength on the surface of the pavement design. The location of the geosynthetic material is pronounced on radarograms, since the layer contributes to the accumulation of moisture, which is reflected by an increased signal amplitude on the surface of this layer. Recommendations on the use of GPR methods for assessing the state of the structural layers of the road pavement of roads at the contact boundaries of neighboring materials are given.
