Environmental cold-mix adjustable-modulus pavement material and manufacturing method thereof

摘要

An environmental protection cold mixing type modulus-adjustable pavement material and preparation method thereof. Equal components of waterborne epoxy resin and waterborne curing agent are added in a container to obtain a waterborne epoxy resin mixture. Emulsified bitumen, the waterborne epoxy resin mixture, an emulsifying agent, a defoaming agent and a stabilizing agent are prepared according to a certain mass ratio; the emulsified bitumen is first added in the container, and the pH is regulated with hydrochloric acid to be 5.0 to 6.5; the above-mentioned other materials are added and stirred to make mixed liquid; a stator of a high-speed shearing machine is put into the mixed liquid, and the rotational speed is set as 350 to 500 rpm for about 20 to 40 min to obtain waterborne epoxy emulsified bituminous emulsion. B. Coarse aggregate, fine aggregate, fillers, cement and the waterborne epoxy emulsified bitumen obtained from the above-mentioned preparation are selected in proportion; and after the coarse aggregate, the fine aggregate and rubber powder are added in a stirring machine of asphalt mixture and stirred and the waterborne epoxy emulsified bitumen is added and stirred, the cement is added and stirred.
