The plant produces BND 70/100 and BND 100/130 road bitumen that proved
effective in the most hard and adverse conditions. It perfectly withstands
heavy loads, which makes it an ideal material for road construction.
BND 100/130 bitumen is universal, recommended for use in all
climate zones.
BND 70/100 bitumen is recommended for all climate zones,
except zone 1, where the average monthly temperature of the coldest season does
not exceed 20 °C.
The raw material used is highly resinous bituminous crude oil from the
Karazhanbas oilfield, which is classified as heavy, resinous, low-paraffin,
sulfurous and highly residuum.
Comprehensive study of the crude oil took place in 2008 and 2011 by
Fushun Research Institute of Petroleum and Petroleum Products (PRC) confirming
the suitability for the production of air-blown and polymer-modified road
bitumen and issuing the initial data for design.
Quality control of products is carried out in the Central Laboratory of
CASPI BITUM JV LLP, equipped with uptodate equipment. The laboratory has
accreditation in accordance with the requirements of GOST ISO/IEC 1702-2019.
Every batch is analyzed for 11 indicators in accordance with the requirements
of ST RK 1373-2013. If the selected sample meets all regulatory requirements, a
quality passport is issued.
The
design capacity of the plant for production of air-blown bitumen is 406.5
thousand tons per year.
