Abstract

The invention discloses a method for emulsifying SBS high-viscosity modified asphalt; the preparation process is suitable for industrial production, and has high viscosity under the premise of simple process, and the SBS high-viscosity modified emulsification obtained in the invention Asphalt is suitable for ultra-thin asphalt wear layer on high-grade roads and special adhesive layer for new roads. It has the characteristics of easy construction, high softening point, good adhesion, easy storage, and the prepared asphalt wear layer has strong anti-loosening ability.

Description

technical field [0001] The invention belongs to the technical field of road engineering materials, and relates to a SBS high-viscosity modified emulsified asphalt material and a preparation process thereof. Background technique [0002] With the rapid development of my country's road traffic, road quality and maintenance technology needs higher requirements. Emulsified asphalt has the advantages of economy, environmental protection and convenient construction. It has been widely used in new roads and old road maintenance projects in recent years. Compared with ordinary emulsified asphalt, SBS modified emulsified asphalt can be used as the adhesive layer and seal layer of new roads, the interlayer and surface treatment of old road renovation and maintenance, and the special binder in various imported technologies, which can meet the needs of modern traffic. Requirements for "high speed and heavy load". However, there are few studies on emulsified asphalt used in road and br...
