Dredging pit pit repair technology is the current highway for a small range of maintenance work is more commonly used method, through a special tool cutting machine and a good asphalt pavement structure of the form of reasonable with the pit slot processing, cutting into a regular square, Pay attention to the bottom of the deal with the bottom to ensure the integrity of the bottom structure; pit surface is best sprayed with a thin layer of emulsified asphalt, and then the input of hot asphalt mixture to ensure the molding effect of rolling. Pay attention to the definition of the operating surface, which is necessary to measure the work to ensure that the cutting diameter is greater than the actual pit more than 10cm, the depth of cutting should also be combined with the actual range of pits to define; In addition, When cleaning, pay attention to the loose part of the pit, the waste material will be dug, to ensure that the excavation from the middle to the surrounding order to ensure that the pit around the bottom and vertical, to prevent the excavation of the surrounding structure damage, loose waste After cleaning, with 3 to 5 pressure of the pump out of the magazine and dust, to ensure that the internal cleaning of the pit is absolutely clean and complete effect.Road Repair Machines

In order to increase the integration of new materials and old materials to prevent the rain into the pit, you need to use the spray gun in the pit structure around the thin asphalt glue, to ensure the amount of moderate, to avoid the phenomenon of oil accumulation on the ground, the middle packing to ensure the height 5cm above the surrounding, the use of layered filling and rolling in the form of improving its compactness and rolling after the surface layer and the original road to maintain the level, if you run the cold feed does not have to consider the packaging of the emulsion coating process, which The construction of rolling technology will be relatively long, but in the life of the increase in a certain advantage.
