Abstract

In the article it is proposed to use polymer-cement foam concrete of normal hardening as one of the layers in order to increase durability and geoprotective of a roadbed. High energy-absorbing properties of the material will help to dissipate the stresses occurring during the passage of heavy transport. The premature failure of the railway embankment will be prevented and overhaul interval increasing. Low coefficient of thermal conductivity and water absorption of the porous layer give the whole construction higher frost resistance, and make it lighter. Levels of the material pores of different size allow it to absorb the pollution from railway transport, providing geoprotective properties.
