Abstract

Summary

A method for the continuous determination of the properties of structural layers based on the GPR method, calibrated by direct measurements of the properties of the structure, is proposed.

The technique relates the change in soil density when compacted with a vibrating roller with a change in the permittivity of the material, as well as with a change in the relative reflectivity.

The effectiveness of the proposed methodology has been tested on the construction section of the roadbed. It is established that the sensitivity of the results of direct measurements is 3 passes of the roller of the used type, and of the GPR method - 4 passes.

The application of the GPR method allows to estimate the uniformity of the density characteristics of the ground along the surveyed section in different depth layers obtained in the continuous mode.
