Abstract
В работе представлены результаты исследований по определению влияния дисперсий цементного камня с различной степенью гидратации в качестве минерального наполнителя на свойства асфальтобетонов. Установлено, что увеличение количества воды затворения, участвующей в процессе гидратации портландцемента приводит к снижению показателя битумоемкости за счет изменения морфологии поверхности зерен минерального наполнителя, увеличения до 3,5 раз объема микро- и мезопор. Показано, что температурная обработка рассматриваемых порошков при 160 о С приводит к незначительному увеличению показателя битумоемкости. Подтверждено образование новых соединений при взаимодействии битума с рассматриваемыми наполнителями. Обоснована возможность использования минеральных порошков из цементного камня различной степени гидратации.
