Problems solved by technology

[0003] However, the existing asphalt cold patching materials for pits have the following common problems when they are used: poor water resistance, poor cohesion and short life. Generally, the existing asphalt cold patching materials will fail within three months of repairing pits. Even when there is a heavy rain, it will all be washed away

Abstract

The invention discloses a high-durability asphalt cold patch material and a preparation method thereof. The high-durability asphalt cold patch material comprises,s by mass, 60-70 parts of coarse aggregate; 30-40 parts of fine aggregate; 4.6-5 parts of an asphalt cold-supplementing liquid; and 2-4 parts of a modifier. The high-durability asphalt cold patch material is simple to produce, energy-saving and environment-friendly; and the high-durability asphalt cold patch material can be packaged by adopting a small barrel plastic bag, can be transported for a long distance, is convenient to use, can directly adopt simple mixing equipment, does not need to be heated, is low in energy consumption and pollution, also has better water resistance and cohesiveness, and ensures the service life.

Description

technical field [0001] The invention belongs to the technical field of road building materials, and in particular relates to a high-durability asphalt cold patch material and a preparation method thereof. Background technique [0002] Potholes are the most common and typical diseases of asphalt pavement. The appearance of potholes is often sudden and tends to expand. If it is not repaired in time, it will become more and more serious and pose a great threat to driving safety. At present, there are two schemes of hot patching and cold patching for pothole repair. Hot repair is to use hot-mix asphalt mixture to repair the pits. Its technology is mature, the source of materials is wide, the material is firmly bonded to the original road surface, and the repair effect is good. Cannot be constructed normally. Cold patching is the use of asphalt cold patching materials to repair pits and grooves. It is easy to use and has low requirements for weather, rain and snow, so it is wi...
