High strength asphalt concrete modifying agent

Abstract

The invention discloses a high strength asphalt concrete additive Lufu Lai(PAC). The formula and the characteristics of the product are as follows: the product comprises the following components: 20 to 70 percent of PE polyethylene, 0.9 to 10 percent of PES polyester, 20 to 50 percent of PVC polyvinyl chloride, 5 to 10 percent of E / VAL(ethylene / vinyl alcohol)copolymer, 3 to 5 percent of rubber, 1 to 4.5 percent of cellulose and 0.1 to 0.5 percent of antiageing agent; the melting temperature(T) is more than or equal to 130 DEG C and less than or equal to 180 DEG C, and the particle diameter(d) is more than or equal to1mm and less than or equal to 6mm(90 percent of the class of products). The product is brown and particle-shaped. The manufacturing process of the invention is as follows: firstly, waste polymer raw materials are put in a waste material crusher and measured respectively; according to the formula ratio, the materials are put in a material mixer, and the mixing materials are put in a hot mixing reactor for processing; and the Lufu Lai(PAC) hot mixing particles are weighted and packaged. The invention is mainly applied to the road surface engineering of a road.

Description

technical field [0001] The invention relates to a concrete additive, in particular to a high-strength asphalt concrete additive. Background technique [0002] Asphalt concrete, which is currently used to build roads, has insufficient load resistance and durability, resulting in frequent problems with high-temperature rutting, low-temperature cracking, water damage, and durability. Roads such as expressways, national highways and high-grade highways that have been built in China often need maintenance and medium- and long-term overhauls. This not only increases the overall cost of road construction and maintenance, but also affects the transportation capacity of roads. From a long-term perspective, it also affects material transportation. The efficiency has also formed a kind of restriction to the rapid development of the national economy and road traffic. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned problems in...
