Abstract

The invention belongs to the technical field of preparation of asphalt additives, and particularly relates to a two-component asphalt anti-stripping agent and a preparation method thereof. The preparation method comprises the following steps: mixing boiler ash, white carbon black, waste ceramic and other substances to obtain a component A; reacting hexamethyldisiloxane, tetramethyldivinylsiloxane,tetraethoxysilane and other substances to prepare a component B. When the two-component asphalt anti-stripping agent is used, the component A and the component B are mixed according to the mass ratioand then added into asphalt, the prepared two-component asphalt anti-stripping agent has good anti-stripping performance, the adhesion between the asphalt and aggregate is high, the heat-resistant stability is good, the water damage phenomenon of an asphalt pavement can be effectively reduced, and the service life of a road is prolonged.

Description

technical field [0001] The invention belongs to the technical field of asphalt additive preparation, and in particular relates to a two-component asphalt anti-stripping agent and a preparation method thereof. Background technique [0002] The existing expressway is often caused by early water damage due to insufficient water stability of asphalt concrete, and the road surface will appear potholes and looseness after 2 to 3 years of use. Water damage, like ruts and cracks, has become the main damage factor of asphalt pavement. The water damage mechanism of asphalt pavement is that the asphalt film peels off from the surface of the aggregate, and its development process is as follows: ① Moisture enters the aggregate interface and exists in the form of water film or water vapor, which affects the adhesion between asphalt and aggregate ; ②Under repeated loads, the asphalt film gradually peeled off from the surface of the aggregate; ③With the further intrusion of water, the aggr...
