Petroleum asphalt anti-stripping agent, preparation method and use method thereof

Abstract

The invention belongs to the technical field of construction materials and relates to a petroleum asphalt anti-stripping agent, a preparation method and a use method thereof. The petroleum asphalt anti-stripping agent comprises the following components in parts by weight: 20-35 parts of fatty acid iron salt, 5-10 parts of hydroxyapatite, 5-10 parts of quaternary ammonium salt and 40-80 parts of gasoline. By using the anti-stripping agent, the adhesion of asphalt acidic building stones is improved, the water damage resistant capability of an asphalt mixture is enhanced, the age resistance of the asphalt is improved, and the service life of road surfaces is prolonged.

Description

technical field

[0001] The invention belongs to the technical field of building materials, and relates to a petroleum asphalt anti-stripping agent, a preparation method and a use method. Background technique

[0002] Spalling is the most common failure of asphalt pavements. The cohesive force between the asphalt film and the aggregate is lost, and it falls off from the surface of the aggregate particles, which shortens the service life of the pavement, increases the maintenance toll, and seriously affects the performance of the asphalt pavement. Therefore, improving the anti-stripping performance between asphalt and aggregates has been a major issue faced by road departments and asphalt research fields for a long time.

[0003] The anti-stripping measures mainly include: use dry ground slaked lime powder or quicklime powder, and cement as part of the filler, and the amount should be 1-2% of the total amount of mineral materials; use the coarse aggregate after being treated ...
