Abstract

The invention relates to an instant high-glue alloy asphalt modified material as well as a preparation method and application thereof. The preparation method comprises the following steps of: uniformly stirring and mixing heavy asphalt aromatic hydrocarbon oil 207, 70 # asphalt and a needle penetration regulator in proportion to form a mixed oil material; adding truck tire rubber powder, uniformlystirring to obtain mixed rubber powder, performing mechanochemical extrusion activation modification through screw extrusion equipment, feeding the mixed rubber powder into a double-cone feeding device, uniformly feeding the mixed rubber powder and a grafting activation modifier into a mixing and granulating extrusion system in proportion under variable-frequency pushing, and performing water cooling, isolation, spin-drying, screening, air conveying, collection and packaging to obtain a finished product of the granular asphalt modified material. The instant high-glue alloy asphalt modified material, the preparation method and the application solve the problems of high processing energy consumption, unsafety, poor heat storage stability, large smoke pollution and insufficient aging performance of the traditional waste tire rubber asphalt modified material, and have the advantages of good asphalt integration, less grinding times, high mixing efficiency, strong waterproof performance andno pungent smell.

Description

technical field [0001] The invention belongs to the technical field of asphalt modified materials, and in particular relates to an instant high-adhesive alloy asphalt modified material, a preparation method and an application. Background technique [0002] With the increasing traffic volume in our country and the increase of vehicles, the quality requirements of asphalt pavement are getting higher and higher. Ordinary asphalt has the disadvantages of being brittle at low temperature and softening at high temperature. It is prone to rutting, Oil flooding, wrapping, shrinkage cracks and other diseases, especially under the conditions of large temperature difference between day and night and obvious shrinkage, ordinary asphalt mixtures cannot meet the characteristics of upper surface tension and deformation tracking, and have great impact on road traffic capacity, driving safety and comfort. Sex has serious consequences. [0003] In recent years, the most commonly used modifie...
