Area of use: construction and reconstruction of highways. The inventive road structure consists of a roadbed, road pavement, shoulders, ventilation ducts, drainage outlets and intake-exhaust chambers. At the same time, the ventilation ducts are filled with rubble and located under the shoulders. In addition, the channels are made with a coating of asphalt concrete and provided with a heat insulating layer in the form of a clip located at the level of the underlying layer of sand, an anti-pouring layer that bends around the lower part of the channel to the clip. Moreover, this layer can be made as closed around the perimeter of rubble, and with an open top. Under the clip and at the bottom of the channel is vapor barrier. Supply and exhaust chambers are located outside the shoulders and connected to the channels in the upper part. If necessary, the supply and exhaust chambers can be equipped with fans. Drainage outlets are made in the form of absorbing wells or asbestos-cement pipes. At high groundwater levels, the bottom of the canals may be provided with drainage pipes.
