Preparation method of dry-process high-viscosity modified asphalt mixture
The invention discloses a preparation method of a dry-process high-viscosity modified asphalt mixture, and belongs to the technical field of modified asphalt mixtures. The technical problems that in an existing wet-process preparation method, a large shearing machine or colloid mill equipment needs to be adopted for fully grinding a modification auxiliary agent, a modified asphalt processing plant is needed, the processing technology time is long, and the storage stability is poor are solved. The preparation method comprises the following steps: step 1, weighing raw materials; the raw materials comprise aggregate, mineral powder, a high-viscosity modifier and matrix asphalt; step 2, heating the aggregate to form a hot aggregate, placing the hot aggregate in a mixing pot, and adding the high-viscosity modifier into the mixing pot for dry mixing; and step 3, heating the matrix asphalt, adding the matrix asphalt into the mixing pot in the step 2, stirring and mixing, then adding the mineral powder, and continuously mixing for a period of time to form the dry-process high-viscosity modified asphalt mixture. The dry-process high-viscosity modified asphalt mixture disclosed by the invention is simple in preparation process and stable in product performance.
本发明公开了一种干法型高粘改性沥青混合料的制备方法，属于改性沥青混合料技术领域；解决了现有湿法型制备方法需采用大型剪切机或胶体磨设备对改性助剂进行充分的研磨，并需要改性沥青加工厂，而且加工工艺时间长，存储稳定性差的技术问题。本发明的制备方法包括：步骤1、称取原料；原料包括集料、矿粉、高粘改性剂和基质沥青；步骤2、加热集料以使其形成热集料，将热集料放置拌合锅内，并将高粘改性剂加入拌合锅内进行干拌；步骤3、加热基质沥青，并将其加入步骤2的拌合锅内进行搅拌和拌合，然后再加入矿粉，继续拌合一段时间后，形成干法高粘改性沥青混合料。本发明的干法型高粘改性沥青混合料制备过程简单，且产品性能稳定。
