Asphalt road surface functional repairing agent and its production

Abstract

A repairing agent for asphalt pavement and its production are disclosed. The repairing agent consists of hard asphalt powder 5-35wt%, heavy mineral oil 16-35wt% and anthracene oil 30-79wt%. The process is carried out by mixing the raw materials at 65-200degree, and reacting for 10-120mins under mechanical agitating and shearing. It's simple and fast, has better permeability, flexibility and elasticity, less hardness, brittleness and viscosity.

Description

technical field

[0001] The invention belongs to an asphalt material composition and a preparation method thereof, more specifically to a road asphalt pavement functional repair agent and a preparation method thereof. Background technique

[0002] During the use of asphalt pavement, the road surface is worn due to the driving of vehicles, the operation of maintenance equipment and environmental influences, such as the rolling of wheels, steel brushes for maintenance vehicles, automobile exhaust, heat cycle and ultraviolet radiation, rain and other factors make asphalt Pavement is prone to aging. The main performance is that the asphalt on the pavement loses its original viscosity, toughness and cohesion to the aggregate, resulting in cracks, water seepage, potholes and other damage phenomena on the pavement, which eventually leads to damage to the pavement structure and shortens the service life of the asphalt pavement. If the asphalt pavement can be ...
