Abstract. The article describes the subgrade, designed from the condition to ensure safe movement of high-speed rolling stock at speeds up to 400 km/h.

Designing subgrade performed for different speeds in conjunction with the design of the upper structure construction path, artificial constructions and engineering communications.

The project envisages the device two protective layers of subgrade throughout the high-speed railway line.

Considered in the article subgrade depending on geotechnical, environmental and other conditions will ensure the maximum accumulated residual deformation of the main site subgrade under ballastless track structure design for the entire service life of not more than 15 mm.

In the design provided the requirements for strength, stability and deformability of subgrade given vibrodynamic trains exposure.
