Also SZHT product line includes improved bitumen petroleum viscous for road building produced from West Siberian petroleum (BDUS). This type of bitumen was developed by KINEF LLC especially for making roadway with extended working period. BDUS is produced by oxidation and compounding of straight-run residues of West Siberian petroleum types. BDUS is produced according to Technical Specification, technical characteristics are listed in the table below.
