METHOD FOR PATCHING ASPHALT CONCRETE PAVEMENTS AND DEVICES FOR ITS IMPLEMENTATION Russian patent published in 2023 - IPC E01C23/09 

FIELD: road repair.

SUBSTANCE: invention relates to patching with small maps of defects on the surface of roads. The patching method includes two successive operations, which are carried out using two devices trailed to the base machine. The first device performs the formation of a recess by first lowering the front part of the towing device with disk knives installed in front of the frame, after the introduction of which, as well as the milling and brush drums, the wheels of the device are lifted and re-supported on support skis located on the sides of the frame. Then the crushed asphalt concrete pavement is moved along the conveyor to a removable hopper placed on the frame, unloading from which is carried out by lifting and overturning the hopper. The second towing device sequentially performs the operations of covering the excavation with a binder, laying the asphalt concrete mixture and compacting it by lowering it onto the support skis located on the frame.

EFFECT: improving the quality of patching and increasing the productivity of the repair process.
