FIELD: technological processes.
SUBSTANCE: method consists in placing a layer of heat-insulating cement concrete under an upper layer of rigid pavement. Layer of heat-insulating cement concrete contains hollow microspheres with coefficient of heat conductivity λ=0.03–0.1 W/m*K and is made in the form of prefabricated plates with compression strength of not less than 25 MPa, in which there are slots of semicircular section for heat exchange elements laying.
EFFECT: preventing slipperiness of road surfaces and protecting them from atmospheric effects.
