Abstract

Summary

The work is aimed at assessing the feasibility of applying the GPR method with the continuous determination of the homogeneity of strength characteristics of the subgrade soil of railways and highways under construction along the GPR profile, and in depth. We demonstrate the distribution of density in different layers in the in-depth direction along the surveyed section of the roadbed during the construction process, after various numbers of soilcompacting machines passes. Good convergence of density values obtained by direct methods and GPR method is shown.
