Pavement asphalt mixture preparation method and device
The present invention relates to a pavement asphalt mixture preparation method, which comprises: 1) screening aggregates to obtain a coarse material, an intermediate material and a fine material, wherein the particle size of the coarse material is not less than 10 mm, the particle size of the fine material is not more than 1 mm, and the particle size of the intermediate material is between 10 mm and 1 mm; 2) drying the asphalt, partially melting to obtain liquid asphalt, and powdering the residual asphalt to obtain powdery asphalt; 3) preheating the coarse material, adding liquid asphalt, stirring the components, adding the fine material, and stirring the components to obtain a coarse prefabricated material; 4) mixing and stirring the powdery asphalt and mineral powder to obtain an asphaltand mineral powder mixture, and 5) mixing the coarse prefabricated material, the intermediate material and the asphalt and mineral powder mixture, uniformly stirring the components, and heating and stirring the mixture. The invention aims to solve the problem of separation during preparation of the asphalt mixture.
本发明涉及一种路面沥青混合料制备方法，包括以下步骤：1)将集料进行筛分，得到粗料、中料和细料，粗料粒度不小于10mm，细料粒度不大于1mm，中料粒度介于10mm和1mm之间；2)将沥青烘干，一部分融化得到液态沥青，剩余沥青打粉得到粉状沥青；3)粗料预热后加入液态沥青进行搅拌，再加入细料进行搅拌，得到粗预制料；4)将粉状沥青与矿粉混合搅拌，得到沥青矿粉混合物；5)将粗预制料、中料和沥青矿粉混合物混合，搅拌均匀后，再进行加热搅拌。本发明的目的是解决沥青混合料制备时的离析问题。
