This paper presents the results of field tests of railway substructure. Dynamic stress sensors were installed to monitor ballast and subgrade dynamic response. Field tests were aimed to study stressed state in terms of train traffic with heavy axle loads. The test results are stress values distribution in ballast in terms of train operation with axle load up to 300 kN. The results show that laying of elastic subballast mats may significantly reduce negative vibrational dynamic impact of heavy axle load on the ballast and substructure.
