Abstract

A thermoset modified additive for asphalt mixture includes the following raw materials: resin, curing agent, promoter, flow agent, filler and additive, wherein the weight part proportions of the raw materials are: resin 35-70, curing agent 1-35, promoter 0-2.5, flow agent 0-6, filler 20-40 and additive 0-2. The asphalt mixture includes thermoset modified additive for asphalt mixture, matrix asphalt or modified asphalt and mineral aggregate, wherein the weight part proportions of the raw materials are: thermoset modified additive for asphalt mixture 1-5, matrix asphalt 2-8 and mineral aggregate 87-97. The thermoset modified additive for asphalt mixture is prepared by dry process modification technology; the prepared modified additive is powdery, has small particle size, and is easy to disperse in asphalt mixture; and the asphalt mixture prepared from the modified additive has simple operation process and low cost, and can be subjected to continuous production.
