FIELD: railway track superstructure.
SUBSTANCE: invention relates to the railway track superstructure, in particular, to the compositions of mixtures for creating a sub-ballast protective layer of the roadbed. The mixture contains components at the following ratio by weight%: ballast weed - 80-90, crushed crushed stone from ballast - 1-10, cement-based hydraulic binder - 3-5, cement modifier - 0.3-0.5, water - 6-8.
EFFECT: invention enables to increase the modulus of deformation of the sub-ballast protective layer increases.
