Abstract

The article describes one of the ways of solution of the actual problem of obtaining quality bituminous materials from residues of paraffin oil recycling. The authors examined the modification of bitumen with polymers, in particular with petroleum resins, polyethylene, and industrial modifiers Elvaloy 4170 and Butonal NS 198. The study was carried out in two ways. We have studied the basic regularities of the joint oxidation of paraffin tar and oil polymerous resins. It was found that the presence in raw materials of oil polymerous resins intensifies the oxidation and reduces the duration of the process of obtaining of bitumen by 1,5-2 times. The article describes the modification of oxidized bitumen with polymer using the compounding method. It was shown that polyethylene increases hardness and the temperature of bitumen softening. The industrial modifiers Elvaloy 4170 and Butonal NS 198 improve the plastic properties of bitumen. Based on the obtained results it was determined that the use of polymer modifiers permits improve the properties of bitumen obtained from paraffin residues
