Abstract

The invention provides an emulsifier as well as a preparation method and application thereof. The invention discloses the emulsifier applicable to emulsifying SBS modified asphalt and used for substituting for an amphiprotic cationic emulsifier, and provides a preparation process for the emulsifier. The prepared emulsifier is used for emulsifying the SBS modified asphalt to obtain high-viscosity modified and emulsified asphalt, and the high-viscosity modified and emulsified asphalt is applied to a pavement ultra-thin wearing course. The preparation method for the emulsifier is simple in operating procedure and moderate in reaction condition, and can be adopted to prepare the high-viscosity modified and emulsified asphalt with high asphalt content, high viscosity and high bonding property.

Description

technical field [0001] The invention relates to the field of building materials, in particular to an emulsifier suitable for modified high-viscosity asphalt, its preparation method and application. Background technique [0002] Ultra-thin wear layer technology is proposed for high-grade pavement with heavy traffic load and high performance requirements. It is mainly used for preventive maintenance of high-grade asphalt or cement concrete pavement, and can also be used as the surface wear layer of new roads. As an effective preventive maintenance technology, the preparation and spraying of high-viscosity modified emulsified asphalt is a key technology in the construction process of ultra-thin wearing layers. [0003] Therefore, it is required that this kind of high-viscosity modified emulsified asphalt not only has high viscosity and cohesiveness, but also can firmly connect the overlay and the original road surface as a whole; at the same time, the high-viscosity modified em...
