Abstract

The invention discloses a composite modifier and a high-scattering-resistance drainage asphalt concrete prepared through the same and relates to the field of road engineering materials. The composite modifier is composed of base materials, fiber, comprehensive additives, cross-linking agent and cross-linking promoter, wherein the base materials are composed of SBS (styrene-butadiene-styrene) modifier, SBR (styrene butadiene rubber) modifier and solubilizer. The drainage asphalt concrete prepared through the composite modifier is high in scattering resistance. Through field deployment of conventional asphalt, aggregate, mineral powder and the composite modifier, a high-performance and stable-performance drainage mixture can obtained and meanwhile is more stable in properties compared with those applying modified asphalt, so that worries on storage segregation and performance degradation of the modified asphalt can be saved, and meanwhile construction deficiencies of dispersing non-uniformity of fiber deployment and grease spots can be completely avoided.

Description

technical field [0001] The invention relates to the field of road engineering, in particular to a modified additive for making drainage asphalt mixture anti-scattering and drainage asphalt concrete prepared therefrom. Background technique [0002] Drainage asphalt pavement refers to a new type of asphalt concrete surface layer with a void ratio of 18% to 25% after compaction and can form drainage channels inside the mixture. Drainage pavement can eliminate the water film formed on the road surface in rainy days and improve driving safety and comfort. sex. In order to ensure a large void ratio, the amount of coarse aggregate in the drainage asphalt mixture accounts for more than 80%. Therefore, the strength of the drainage asphalt pavement is reduced, and the aging of the asphalt will cause the mortar to crack, and the coarse aggregate in the drainage asphalt pavement The phenomenon of falling off in pieces and flying occurs, which is accelerated by external forces such as h...
