ЭКСПЕРИМЕНТАЛЬНОЕ ИССЛЕДОВАНИЕ УПРОЧНЕНИЯ НЕСВЯЗНЫХ ГРУНТОВ КРОШКОЙ ИЗ ШИН И БИТУМОМ Experimental investigation of Reinforcement of Grain Soil with Tire Crumb and Bitumen and its Environmental Effects

Saeed Khaki Khatibi

Аннотация


Проведено исследование влияния добавления крошки из шин и битума на параметры прочности грунта на сдвиг. Испытания показали, что параметр прочности на сдвиг при добавлении в грунт резиновой крошки сначала увеличивался, максимально на 17% когда содержание крошки достигло 2%, а затем снижался. Прочность на сдвиг грунта, усиленного добавлением 10% крошки из шин, была примерно равна прочности на сдвиг неармированного грунта. Установлено, что присутствие крошки из шин в смеси приводит к снижению удельного веса образцов. Битум уменьшал угол трения и повышал сцепление с грунтом.
