Preparation method of direct-vat granular colored asphalt mixture
The invention relates to the technical field of colored asphalt, and discloses a preparation method of a direct-vat granular colored asphalt mixture, which comprises the following preparation steps: 1) putting hot aggregate into a stirring pot for stirring and washing the pot; 2) putting the aggregate into a stirring pot, and heating to a set temperature; (3) adding the colored asphalt particles into a stirring pot, and then adding SBS (styrene-butadiene-styrene) modified asphalt; (4) mixing the aggregate in the stirring pot with the granular colored asphalt, and stirring for a set time at a set temperature to form a mixture without a gray material; the stirring pot is preheated and cleaned in advance, then the stirring pot is heated, the heating time is saved, the cleaning efficiency is improved, the aggregate is stirred at the set temperature for the set time, a mixture without gray materials is formed, the preparation process is simple and easy to control, and the problems that the aggregate is cooled due to the fact that the aggregate stays in the stirring pot for a too long time, and the service life is prolonged are solved. And the preparation process is complicated. The invention also solves the problems in the prior art.
本发明涉及彩色沥青的技术领域，公开了直投式颗粒状彩色沥青混合料制备方法，包括以下制备步骤：1)、利用热骨料置于搅拌锅中进行搅拌洗锅；2)、将骨料放置入搅拌锅中加热至设定温度；3)、将彩色沥青颗粒投进搅拌锅内，再添加SBS改性沥青；4)、将搅拌锅内的骨料与颗粒彩色沥青混合在设定温度搅拌至设定时间，形成不含花白料的混合料；提前对搅拌锅进行预热清洗，再将搅拌锅加热，节省加热时间并且提高了清洗效率，将骨料在设定温度搅拌至设定时间，形成不含花白料的混合料，该制备过程简单且容易控制，解决了骨料在搅拌锅停留的时间过长降温，容易出现花白混合料的以及制备过程复杂的问题。
