This paper presents the results of field tests of railway structure. Operating experience of subgrade has shown that with increasing weight and speed of trains, even at the constant axle loads, subgrade deformations appear on those places, where they have not been before. In order to identify the vibration distribution in the subgrade soils during the passage of heavy trains, experimental studies were conducted. The test results are vibrational acceleration distribution in ballast layer and experimental relationships of vibrational accelerations damping in terms of train operation with axle load up to 300 kN. The intensity of the accumulation of uneven residual deformation of the railway track increases as a result of this exposure that affects not only on the roadbed, but also on constructions of buildings and construction. The elastic subballast mats are used for reducing the negative impact of vibration.
