BACKGROUND OF THE INVENTION A machine for repairing asphalt concrete coatings is known, comprising a self-propelled chassis, on the frame of which a hopper with a tray, containers for binder and liquefied gas, a planner and a vertically movable infrared radiation heater with an additional frame are mounted, and the machine is equipped with a vibration roller mounted with adjustable rods and brackets on an additional frame fixed to the chassis by means of shock absorbers, the heater is made of articulated sections having a central the first part of the opening in which the hopper tray is located, the heater sections being placed above the roller and with the possibility of changing the angle of inclination to the road surface by means of adjustable traction, and the scheduler is rigidly attached to the hinge of one of the heater sections and to the roller axis (see.with. SU No. 690110, IPC E01C 23/06, E01C 19/26, publ. 10.10.1979).

The disadvantage of this machine is the low productivity and quality of road repairs.

A known method and machine for the restoration of the old pavement, including a machine for restoring pavement, the first stage determines the characteristics and quantitative composition of the binder to be added during regeneration to obtain a restored coating, the characteristics of which would correspond to the characteristics of the initial coating, at the second stage, cut old coatings with special bodies equipped with milling heads for receiving crumbs from the cut-out part of the coating , which enters the level of mixing organs, where a reducing binder is added to it, the characteristics of which are determined at the first stage (see French application No. 2613737, IPC E01C 23/03, publ. 10/14/1988).

The disadvantage of this method and machine is the low quality of the restoration of the coating and adhesion of the newly laid coating layer to the old one.

The closest in technical essence and the achieved positive effect and adopted by the author for the prototype is a machine for the regeneration and compaction of asphalt concrete coatings, containing a self-propelled chassis with a hydraulic station for driving the drive and working bodies, a device for receiving and supplying new asphalt concrete mixture to the working bodies, a gas heating system old coating, a working body for breaking open the old coating and mixing the new material with the old one, having a sectional screw cutter and mixer with hydraulic and a device for introducing a reducing agent, consisting of a tank, pumps for filling and feeding a reducing agent, a distributor with nozzles, a throttle controlled by a hydraulic cylinder with a piston centered by means of a calibrated spring, connected via a manual control unit to a control pump and, using a distributor, a pressure head a hydraulic drive line of the mixer or auger-cutter, which seals the working body, while the rod of the throttle control cylinder is equipped with a plunger nozzle connected to the pressure head ralyu hydrodrive mixer or screw-cutters, the two cylinder cavities are connected to a manual control unit and a distributor nozzle connected to the pump supplying the reducing agent by means of nozzle, which volume is less than second pump capacity, and check valve opening pressure setting which is higher than the injectors settings (see. A.S. SU No. 1472553, IPC E01C 23/08, publ. 04/15/1989 g).

The disadvantage of this device is the design complexity, low reliability.
