Embodiment Construction

[0024] See Figure 1, a new process for repairing potholes on asphalt pavement. This process is to first clean the damaged potholes at room temperature, trim the periphery and bottom of the potholes according to the specified size, and then make the pre-prepared potholes corresponding to the size of the repaired pits. Apply pavement asphalt brick adhesive on the bottom, side, and pit bottom of the pavement asphalt bricks, bond the pavement asphalt bricks to the bottom of the pit and the cutting surface, and keep the road surface smooth, and then use the pavement asphalt brick adhesive to seal the pavement asphalt The gap between the brick and the original pavement is filled, and the technical standard of the original pavement can be reached after a short period of health maintenance, and the pothole repair of the pavement can be completed.

Abstract

The present invention relates to road maintenance technology, and is especially fast process of repairing pit in asphalt road. The fast process of repairing pit in asphalt road includes the steps of: cleaning pit, cutting the edges and bottom of the pit to certain sizes, adhering prefabricated road asphalt brick to the pit with asphalt adhesive, filling the gaps with asphalt adhesive and short time curing. The technological process has the advantages of environment friendship, saving in energy, low cost, short operation time, high strength and high durability of the repaired road, etc.

Description

technical field [0001] The invention relates to the field of traffic road maintenance, and is a new technique for repairing potholes on asphalt pavement. Background technique [0002] Potholes in roads are a common disease of asphalt concrete pavements all over the world. In the current road maintenance, asphalt concrete pavement potholes are repaired. In summer, joint cutters and crushers are often used to dig out square pits. The comprehensive maintenance vehicle heats the asphalt concrete to 200 degrees Celsius before paving, and then uses a small road roller (or flat plate tamping) rolling repair process; due to the constraints of weather conditions in northern cities and ordinary roads in winter, road potholes are basically not repaired, and asphalt cold patching is often used for pothole repair on expressways. The disadvantages of the current construction technology are: there are many operating machinery and equipment, the repair process is cumbersome, the operation ...
