Problems solved by technology

However, the quality of domestically produced cold patching materials varies from good to bad. Cold patching materials are poor in low-temperature and high-temperature resistance. They are prone to embrittlement and crusting in low-temperature environments, and are easy to soften in high-temperature environments, resulting in poor road surface flatness, and cold patching materials often have low initial strength. High, resulting in poor performance, easy to loose and fall off, making cold patching can only be used as a temporary treatment for diseases

Abstract

The invention relates to a cold patch material for disease repair of asphalt road pavements. The cold patch material is prepared from aggregate, asphalt and a cold patch agent, wherein the aggregate is prepared from crushed stone, machine-made sand and ore powder; the particle size of the crushed stone is 5mm to 16mm; the ratio of oil to stone is 4 to 6%; the amount of cold patch agent in the coldpatch material is 1.0 to 1.5%. The asphalt cold patch material has the characteristics that the defects of easiness in caking, poor durability and poor peaceability in the traditional cold patch asphalt mixture are overcome; the repair can be performed at any time, the peaceability is good, the temperature stability is good, the forming strength is high, the water stability is excellent, the durability is good, the storage is easy and the like; the service life of the cold patch material is effectively prolonged; the application prospect is broad.

Description

technical field [0001] The invention belongs to the field of asphalt mixture preparation, and relates to a cold patch for asphalt pavement disease maintenance and a preparation method thereof. Background technique [0002] As a seamless continuous pavement, asphalt pavement has good mechanical strength, can adapt to various driving loads, and has the advantages of stable driving, comfortable driving, low noise and easy maintenance, etc., and has been more and more widely used. . During the long-term use of asphalt pavement, there will be pits, looseness, peeling and other diseases, which will affect the normal use of the road and even cause traffic accidents. Therefore, it is necessary to repair the pits, damage and other diseases on the road surface in time. There are two types of pavement pothole repair: hot repair method and cold repair method. Traditional hot repair construction is feasible for road repairs with concentrated locations and large engineering quantities, ...
