Method for repairing boundary and reinforcing for bituminous pavement pit slot

The invention discloses a method for repairing boundary and reinforcing for a bituminous pavement pit slot, comprising the following steps: after excavating and clearing up a pit slot in the bituminous pavement, backfilling a repair material to the pit slot, wherein a seam formed on the road surface is called as a repair boundary; firstly painting a layer of binding agent to the repair boundary, then paving a layer of non-woven fabric to the binding agent and covering the repair boundary, and finally painting a layer of bitumen on the non-woven fabric and spreading a layer of macadam, wherein the distances from two sides of the non-woven fabric to the repair boundary are both longer than 5cm, and the cover area of the binding agent at the lower layer of the non-woven cloth and the cover area of the bitumen at the upper layer of the non-woven cloth are both larger than the cover area of the non-woven cloth. The method can effectively prolong the service life of the bituminous concrete pavement after pit slot repair and is applicable to various pit slot repair boundaries of the bituminous concrete surface layer.
