FIELD: construction.SUBSTANCE: invention relates to road construction, namely, to patching of asphalt concrete pavements. A method for patching roads is that the defective pavement area is milled, cleaned from dust and ground, treated with bitumen emulsion, after which the mixture is placed and rolled. The asphalt mix is placed in the pothole with arrangement of a small conical mound near the edge of the arranged pavement, before the drum of the road roller, with account to the pressing-out of the road material towards the edges of the pad when the roller runs over the mixture, and for compacting the asphalt mix a compact vibratory roller is used in the dynamic operation mode; the final stage of compaction process is the use of plate compactors for additional compacting of the borders of the repair area after the vibratory roller.EFFECT: improvement of uniformity of the compacted pavement, improvement of strength and durability.1 dwg |
