Abstract
Summary
Road construction projects for railways and highways establish the required roadbed compaction rates. When carrying out construction work, obtaining the desired indicators depends on the accuracy of measuring the moisture of the soil material, and the technology for bringing the moisture to the optimum level. This study is aimed at the developpment of a GPR technology for determining the moisture content of soil materials of structural layers prepared for compaction work during the construction of roadbeds of railways and highways. Experimental measurements are performed on draining soils represented by fine river sand.
