ENSURING FROST RESISTANCE OF THE SUBSHALE BASE OF THE TRACK DURING THE MODERNIZATION OF THE EASTERN LANDFILL
With the modernization of the eastern polygon, it is planned to significantly increase the capacity of roads through the construction of new and second tracks. In these difficult engineering and geological conditions, it is important to create a solid and stable foundation for the future road for its effective operation. The use of overhead and mortise pillows made of asbestos ballast makes it possible to simplify the anti-deformation design and most effectively solve the problem of strengthening the sub-floor base. Among the favorable qualities of asbestos ballast should be attributed to high anti-spring properties, high load-bearing capacity and resistanceto vibration effects, low water permeability and relatively constant maintenance.stable humidity regime. At the same time, the selling price of asbestos ballast is 3 times less than the cost of crushed stone and sand mixtures.
