Study of Production of Rubber-Bitumen Compounds

Abstract

In this article were investigated ways of production of Rubber-Bitumen Compounds (RBC). The physico-mechanical characteristics of paving bitumen BND 60/90 modified with rubber crumb from spent tire and spent engine oil. The structure of rubber crumb was characterized by optical microscopy and physico-mechanical characteristics of rubber-bitumen compounds are determined by standard methods. It established that the quantity of entered rubber-oil depending (ratio 3:2) on physical and chemical conditions. 15-25 wt.% rubber-oil modified bitumens were according to variety standard of RBC.

Study of Natural Bitumen Extracted from Oil Sands

“…The properties of bitumen were described by physical tests [4,13]. Penetration involves the determination of the extent to which a standard needle penetrates a properly prepared sample of bitumen under specified conditions of temperature, load, and time.…”

“…In Republic of Kazakhstan the satisfaction of need for a bitumen material occurs due to its import from Russia and Iran. So the problem upgrading of domestic raw materials are actually [13,14].…”

Ways of Using Rubber Crumb from Worn Tires

“…Crumb rubber modified bitumen can improve the heat-resistance, the crack-resistance at low temperature and the durability of bitumen. As a result, the pavement quality grows, and its service life becomes a factor of 1.5 -2 longer [13][14][15].…”
