Abstract

The invention discloses an asphalt anti-stripping agent as well as preparation and application methods thereof, and relates to the technical field of asphalt additives. The asphalt anti-stripping agent comprises the following components in parts by mass: 3.7-6.5 parts of paraffin, 2.2-4.2 parts of fatty acid and 2.5-5.5 parts of sodium lignin sulfonate. The preparation method of the asphalt anti-stripping agent comprises the following steps: adding paraffin, fatty acid and sodium lignin sulfonate into a mixer in parts by mass, and stirring at a temperature of 70 to 90 DEG C until the components are uniformly mixed. The application method of the asphalt anti-stripping agent comprises following steps: 98%-99% of matrix asphalt is heated to 220 DEG C, 1%-2% of the asphalt anti-stripping agentas described in any one of claims 1-2 is added, and an obtained mixture is stirred and mixed at 220 DEG C for 3 hours. The asphalt anti-stripping agent disclosed by the invention is prepared by proportioning low-cost materials at high temperature, has good water resistance and high-temperature resistance, and when the asphalt anti-stripping agent is applied, the asphalt anti-stripping agent and matrix asphalt are mixed and stirred at high temperature, so that the use amount is larger, but the effect is better.

Description

technical field [0001] The invention relates to the technical field of asphalt additives, in particular to an asphalt anti-stripping agent and a preparation and application method thereof. Background technique [0002] In the preparation process of anti-stripping asphalt, it is necessary to add asphalt anti-stripping agent to the base asphalt. Currently, the anti-stripping asphalt prepared by common asphalt anti-stripping agents in the market has insufficient water resistance and poor high temperature resistance. Contents of the invention [0003] In order to solve the problems in the prior art, the present invention provides an asphalt anti-stripping agent and its preparation and application method. The asphalt anti-stripping agent is formulated at high temperature through low-cost paraffin, fatty acid and sodium lignosulfonate Compared with the preparation, it has good water resistance and high temperature resistance. When applying this asphalt anti-stripping agent, the ...
