Abstract

The invention discloses a high performance reclaimed asphalt pavement cold patch material, which comprises the following components by mass percentage: 2-5% of high aromatic hydrocarbon oil; 0.05-0.1%of a plasticizer; 0.1-0.4% of a polymer modifier; 0.1-0.2% of a latex modifier; 0.7-1.5% of kerosene; and 93-97% of a waste asphalt pavement milling material. The high performance reclaimed asphalt pavement cold patch material provided by the invention uses the surface milling material of waste asphalt road as the production raw material, solves the problems of environmental pollution and recycling of asphalt road milling waste, is more environmentally friendly and resource-saving than the existing product technology; high aromatic hydrocarbon oil, the plasticizer and the polymer modifier areemployed for regeneration and performance reinforcement treatment on aged asphalt in waste aggregate, thus restoring and strengthening the high temperature and low temperature performance of aged asphalt. The invention also discloses a preparation method of the high performance reclaimed asphalt pavement cold patch material.

Description

technical field [0001] The invention relates to the field of petroleum processing products, in particular to a high-performance recycled asphalt pavement cold patch and a preparation method thereof. Background technique [0002] Because asphalt pavement has many advantages such as smooth road surface, comfortable driving, wear resistance and anti-skid, low noise, suitable for mechanized construction, etc., it is currently widely used on all levels of roads in our country. However, during the use of asphalt pavement, due to the long-term exposure to the sun, rain, freeze-thaw and other climate effects, coupled with the continuous rolling of vehicles, various local cracks, potholes, damage, cracks, etc. often appear on the pavement. disease. The emergence of pavement diseases not only reduces the performance of asphalt pavement, affects the normal traffic of the road, but also increases the probability of traffic accidents. Therefore, various diseases on asphalt pavement must...
