Polymer Modified Bitumen for Russian roads: quality, reliability and safety
In October 2014, production of polymer modified bitumen and bitumen emulsions started at the new plant built by JV Gazpromneft Total PMB on the Gazpromneft’s Moscow refinery industrial site. At full capacity the plant will produce annually 60.000 tons of bitumen and 7.000 tons of bitumen emulsions.
The new plant was inaugurated on September 30, 2014, in the presence of the Moscow Mayor Sergei Sobyanin. - These new bitumen will help us to improve not only Moscow’s ecology, but the quality of the roads in our capital city as well, - Sergei Sobyanin said at the ceremony.
The plant was inaugurated on September 30, 2014, by Gazpromneft CEO Alexander Dyukov and Moscow Mayor Sergei Sobyanin.
The new plant built by JV Gazpromneft Total PMB produces polymer modified bitumen and bitumen emulsions G-Way Styrelf.
Total has been helping to build roads worldwide for more than 40 years. The Group is the leading asphalt producer and supplier in Europe, marketing 12 product lines with more than 400 different asphalt products.
Total's research center in Solaize (France) develops high-tech petrochemical products for wide range of applications.The Styrelf® product line includes several grades of bitumen binders for roadways and bitumen emulsions for construction industry.
Making energy better through technological excellence
The new facilities use the Styrelf® polymer modification technology developed in the Total Group, presently 3rd largest patent holder in this field in the world.
The G-Way Styrelf product line includes 4 grades of polymer modified bitumen:
G-Way Styrelf 60 Standard,
G-Way Styrelf 60 Premium,
G-Way Styrelf 90 Standard,
G-Way Styrelf 90 Premium.
The Standard grades are fully compliant with or exceeding the Russian national standard ГОСТ Р 52056. The Premium grades are high-tech products providing for the best quality roadways. Their parameters are in compliance with the highest grade of Superpave (Superior PERforming Asphalt PAVEments) performance grading.
The products’ compositions have been specially designed for Russia, using the standard bitumen produced by the Moscow refinery as a base. The raw product will be supplied directly by the refinery’s main bitumen plant which has become the biggest in Europe after the recent refurbishment, with a capacity of 1.7 MT per year.
The modifying agent, when added to the bitumen, initiates the 3D polymer bond forming. The use of such modified bitumen in the bituminous concrete mix allows for the roadway stability in a wider temperature range and for a better resistance to rut and cracks formation.
High technologies for better road safety
Improved roadways are not only cost efficient, with the road repair intervals doubled; their quality has direct influence on the traffic safety. The ruts (also called “washboard”) are known to negatively affect the wheel’s grip to roadway, thus impairing the vehicle’s dynamic stability and maneuverability. The high-tech bitumen produced under Total technology allow to maintain the roadway in a good state for a longer period. It is especially important for Russia, where there are considerable seasonal temperature variations in most regions, and the use of spiked tires during the long winter season adds to the general wear and tear of the roadways.
