The article presents theoretical studies of the interaction of the compacting machine with the soil of the road bed of the railway embankment. The results of the studies make it possible to establish the parameters of the sealant, which ensure an efficient flow of the compaction process of the ground environment. It is established that the rigidity of the working body of the roller must vary over a wide range. Experimental studies of a new sample of the working body confirmed the possibility of adjusting the rigidity in the required range for the effective use of vibrating rollers in the construction of railroad soil embankments.
