Abstract
In the paper ways of using rubber crumb from worn tires were investigated. Possibilities of preparing Rubber-Bitumen Compounds (RBC) based rubber crumb (RC) from worn tires were studied experimentally. The physico-mechanical characteristics of paving bitumen BND 60/90 modified with rubber crumb and spent engine oil. The structure of rubber crumb was characterized by optical microscopy. Physico-mechanical characteristics of RBC were detrminated by standard methods. It is established that the quantity of entered binders depending on physical and chemical conditions, which was optimal composition of rubber-oil at a ratio of 1:1 and 3:2 and introduction to bitumen in amount of 15-25 wt.%.
