Abstract

Summary

The work reports on the GPR technology for determining the thickness of geocomposite formed in the railway track ballast shoulder upon polymerization of two-component polyurethane-based binder «RT-CS-001» introduced into ballast material.

It is shown that when the ballast voids are not filled with the polymer, visible depth of the contrast lower boundary of the ballast layer on a radargram is proportional to the thickness of the geocomposite formed.

Thus, the thickness of geocomposite can be determined by GPR using predetermined refractive indexes of ballast material and geocomposite.
