Specialists from Gazprom Neft Bitumen Materials (operator of the Gazprom Neft bitumens business) will develop formulations for asphalt mixes (bitumen-concrete mixes) meeting the particular requirements and road conditions of the Omsk Oblast, will provide technical support in road-building and asphalt paving, and will make recommendations on managing road-building operations.
Gazprom Neft CEO Alexander Dyukov commented: Gazprom Neft has been developing its bitumens business as a separate and independent entity since 2008 and, during this time, has gained the qualifications and experience that have allowed us to become Russias market-leading supplier of high-technology products, as well as successfully selling bitumen products abroad.
In order to get longer periods between repairs and to reduce the total cost of road pavements polymer modified bitumens (PMBs) as new bituminous materials have to be developed.
Two bitumens, BIT 70/100 (marked as Bl) and BIT 50/70 (marked as B2), were used to produce blended, polymer-modified bitumens, PMBs.
Currently for the road construction in Poland most commonly are used unmodified bitumens 20/30, 35/50, 50/70 (where 20/30 is a penetration range) and polymer modified bitumens PmB 25/55-60 and PmB 45/80-55 (where 25/55 is penetration rang and 60 is a softening point).
Bitumens produced in Poland are obtained from Russia crude oil.
Among the topics are polymer modified bitumen emulsions, modifying bitumen using polyurethanes, using waste polymers to modify bitumens, factors affecting the rheology of polymer-modified bitumen, natural weathering in styrene-butadiene modified bitumen, and the fuel resistance of bituminous binders.
This type of construction and technological parameters must prohibit bitumens ageing from oxydation, cooling down, overheating and also sediment formation in the coil.
10] for the bitumens extracted from Athabasca oil sands.
Considering a huge territory of the Russian Federation, characterized by a wide range of operating temperatures, one of the ways to increase the transport and operational performance of pavements is to modify bitumen with different polymeric additives in order to extend the temperature range of reliable performance of asphalt concrete pavements.
The bitumen is heavy hydrocarbons by-products, black residues of crude oil obtained by direct distillation, serving in the covering manufacture in hot conditions.
