Renovation of pits and grooves (trimming, slag removal, scraping and oiling) → packing leveling (layered packing shaping) → compaction (plate rammer, aluminum pressure plate, small road roller, off-road rolling can be commanded).

Repair pits and grooves:

Step 1: clean the pit and groove. When the pit and groove are large, the periphery and bottom surface should be neat with hard stubble, which is more conducive to giving play to the bonding type of Jiage asphalt cold patching material.

Step 2: Fill the pit with a proper amount of Jiage asphalt cold patching material. If the pit depth is more than 8cm, it needs to be compacted by layers. The virtual paving thickness of filler depends on the degree of compaction, which is generally 1-2cm.

Requirements: The repair surface should be smooth, smooth, free of wheel tracks and loose edges.

Emergency repair of large-scale pavement;

When excavating the pavement due to large area damage or pipeline rupture, the subgrade should be solidified and compacted to have corresponding bearing capacity, and then spread and compacted in layers. In this case, it needs to be compacted with a plate rammer or a roller.
