A kind of asphalt pavement repair agent

Abstract

The invention provides a kind of asphalt pavement repairing agent, comprise regenerated asphalt, asphalt emulsifier, mineral material, MPE amount, antistripping agent and plant fiber; Wherein, described asphalt emulsifier consumption is 10-15% of regenerated asphalt amount, Asphalt emulsifier and regenerated asphalt form the amount of mixed asphalt; the amount of mineral material is 6-10% of the amount of mixed asphalt, the amount of MPE is 5-8% of the amount of mixed asphalt, and the amount of anti-stripping is 5% of the amount of mixed asphalt 0.4-1.0%, the plant fiber consumption is 0.3-0.6% of the mixed asphalt amount, the present invention forms the asphalt pavement repair agent by utilizing asphalt emulsifier and MPE amount and an appropriate amount of anti-stripping agent, or utilizes recycled asphalt, asphalt emulsifier , Mineral material, MPE content, anti-stripping agent and plant fiber constitute the asphalt pavement repair agent. When facing slightly damaged asphalt pavement maintenance, the process is simple, the flexibility of selection is high, the repair cost is reduced, and it is economical and practical.

Description

technical field [0001] The invention belongs to the technical field of asphalt pavement repairing agent, in particular to an asphalt pavement repairing agent. Background technique [0002] Asphalt is a dark brown complex mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives. It is a kind of high-viscosity organic liquid. It is liquid with a black surface and is soluble in carbon disulfide. Asphalt is a waterproof, moisture-proof and anti-corrosion organic gelling material. Pitch can be mainly divided into three types: coal tar pitch, petroleum pitch and natural pitch: wherein, coal tar pitch is a by-product of coking. Petroleum asphalt is the residue after distillation of crude oil. Natural bitumen is stored underground, and some form ore layers or accumulate on the surface of the earth's crust. Asphalt is mainly used in coatings, plastics, rubber and other industries as well as paving roads. [0003] During the long-term use ...

AI Technical Summary

Problems solved by technology

[0003] During the long-term use of asphalt pavement, due to the influence of climate and vehicle conditions, there will be aging phenomena, which will affect the service life of the pavement. Regular maintenance or repair work on the asphalt pavement is required

[0004] When the existing asphalt pavement repair agent is used to repair slightly damaged pavement, the process is relatively complicated, and the effect of the repair agent is poor, which makes the investment cost larger when facing slightly damaged asphalt pavement repair, which affects the repair efficiency of asphalt pavement
