Изучены характеристики формы частиц щебня и дана оценка их влияния на физико-механические свойства получаемого дробленого продукта. Результаты исследования показали, что различные стадии переработки габбродолерита на щебень влияют на эти свойства. После трех стадий дробления щебень обладает улучшенными прочностными характеристиками — потери массы уменьшились при определении дробимости в 1,5–2 раза по показателю микро-Деваль (в среднем на 2,4 %). Моделирование износа частиц показало изменения характеристик формы: округлость увеличилась, шероховатость поверхности и плоскостность уменьшились, а удлинение практически не изменилось. Анализ физико-механических свойств и формы частиц щебня позволил установить некоторые закономерности его применения.
