Abstract
In the article bitumen and asphalt concrete qualitative properties depending on using rubber, the crumb is considered.Bituminous binders' comparative physical and mechanical characteristics containing modified crumb are given.It is proved that the increase in the quantity of Kulantau vermiculite leads to a decrease in the thickness of bitumen films on the particle surface.The modification by rubber crumb allows to increase the quality of the bitumen binder, durability of the coatings and to reduce the cost of asphalt coatings, as well as to utilize largetonnage rubber products waste.
