High modulus asphalt concrete additive agent

Abstract

The invention discloses a high modulus asphalt mixture additive (Rohillard PAC-M), the formula is as follows: polyethylene PE: 20 to 70 percent, polyester PES: 0.9 to 10 percent, polypropylene PP: 15 to 60 percent, polyvinyl chloride PVC: 20 to 50 percent, chlorinated polypropylene PP-C: 5 to 10 percent, rubber: 3 to 5 percent, asphalt: 1 to 6 percent, cellulose: 1 to 4.5 percent and auxiliary agent: 0.1 to 0.5 percent. The product is characterized in that the polymerization temperature is T, T is not less than 130 DEG C and not more than 190 DEG C, and the particle size d of the product is is not less than 1mm and not more than 6mm, the particles are granular (90 percent of the product). The color / shape of the product is dark brown. The high modulus asphalt mixture additive is mainly applied in the new construction and the overhaul of high-grade highways, heavy traffic roads and transportation main trunk line roads, as well as the curing and other road projects. The high modulus asphalt mixture additive is mainly characterized in that: the high modulus asphalt mixture additive has great advantages of high-temperature rut resistance, low-temperature cracking resistance, prevention of water damage and durability.

Description

technical field [0001] The invention relates to a high modulus asphalt concrete additive. The high modulus asphalt mixture additive technology belongs to the field of chemical industry, and is a new type of polymer functional material compounded. The application object is the field of traffic road pavement construction. It is a special new material for road and expressway pavement construction. It is applied to road construction to mainly improve the load modulus of the road surface, improve the elastic recovery function of the road surface, resist rutting, and effectively prevent early damage to the road surface. , prolonging the service life of roads is a technological innovation in road construction materials in the field of road construction. Background technique [0002] On the one hand, the asphalt concrete used for road construction has limited load-resistant deformation capacity and road surface recovery capacity after deformation under load, which often leads to hi...
