Abstract

The invention discloses a permeable regenerated sand mist-containing sealing layer material and a preparation method thereof. Organic solvents, synthetic thermoplastic acrylic resins, solid asphalt particles, active regeneration agents and modified organosiloxane wear-resistant additives, thermoplastic The sand mist seal layer material prepared by mixing elastomer thickener and fine sand is an oily material, which has good permeability and regeneration performance on the asphalt surface layer, and the prepared sand mist seal layer material has high strength, The anti-skid performance and waterproof performance are good, the bonding strength with the original asphalt pavement is high, and the wear resistance is good; the preparation method is convenient and easy to operate, and the energy consumption is low, and it is suitable for large-scale construction application in the preventive maintenance of asphalt pavement.

Description

technical field [0001] The invention belongs to the technical field of road asphalt maintenance materials, in particular to a permeable regenerated sand mist-containing sealing layer material used in preventive maintenance of asphalt pavement and a preparation method thereof. Background technique [0002] Sand mist seal technology is a commonly used preventive maintenance method. Fine-grained sand is mixed with modified emulsified asphalt, and special additives are added to make it evenly and stably suspended, and then sprayed on the road surface through high-pressure equipment, eliminating the need for after-sales maintenance. The two-step process of sanding and rubber wheel rolling, and because the fine-grained sand is fully covered by the mortar, it is more uniform, firm and stable than sanding and rolling, and has a better performance than ordinary fog seals. Anti-slip properties. [0003] Chinese patent CN108585621A "A kind of asphalt-based concentrated cover material ...
