Abstract
Способ приготовления битумоминеральной композиции, включающий подачу в сушильный барабан заполнителя и добавки, подачу в смеситель отдозированных составляющих компонентов композиции и перемешивание при температуре 120-160°C, отличающийся тем, что составляющие компоненты подают в работающий смеситель в следующей последовательности: щебень → песок → битум → минеральный порошок, причем на стадии сушки и перемешивания щебеночных и песчаных фракций в сушильный барабан в качестве поверхностно-активной добавки подают смесь высокомолекулярной жирной кислоты (ЖК) с числом углеродных атомов С более 18 и диэтиленамин (ДЭА) при их соотношении от 1:0,07 до 1:0,1 в количестве 0,4-0,8% от массы заполнителя. A method of preparing a bitumen-mineral composition, comprising feeding aggregate and additives into the dryer drum, feeding the metered components of the composition to the mixer and mixing at a temperature of 120-160 ° C, characterized in that the constituent components are fed into the working mixer in the following sequence: crushed stone → sand → bitumen → mineral powder, moreover, at the stage of drying and mixing of crushed stone and sand fractions, a mixture of high molecular weight is fed into the dryer drum as a surfactant oh fatty acid (FA) with a number of carbon atoms greater than 18 and dietilenamin (DEA) in a ratio of from 1: 0.07 to 1: 0.1 in an amount of 0.4-0.8% by weight of the aggregate.
