METHOD TO CONSTRUCT MOTOR ROADS AND MOTOR ROAD DESIGN Russian patent published in 2013 - IPC E01C3/04 E01C21/00 

FIELD: construction.

SUBSTANCE: method to construct motor roads includes erection of trenches and water drainage devices, preparation of a soil earth bed, erection of an underlying layer and a road surface, at the same time the main layer is arranged between the underlying layer and the road surface, and the soil earth bed is prepared by its levelling with coating by a binding additive and its further rolling, and if there is no soil earth bed, it is previously formed by means of application of a mixture of sand, ash slags and/or wastes of coal production, water and a binding additive, and the underlying layer is formed from a mixture of cement, sand, filler of fine fraction or clay or fine gravel, or wastes of heat power plants, water, binding additive, which is laid, levelled and compacted, then the binding additive is either sprayed or sprinkled, with further compaction of needle rollers to density of at least 1600 kg/m³, and the main layer of the road surface is formed from natural gravel, sand and/or sand clays, stabilisers in the form of cement, and/or lime, and/or bitumen, and/or asphalt concrete and binding additive. Also motor road design is described.

EFFECT: production of strong structured layers of motor roads connected both to each other and between layers, increased even stability of road surface in process of operation by means of provision of continuous growth of road strength in time.
