STANDARD INDICATORS OF MODIFIED BITUMENS

NEWS of National Academy of Sciences of the Republic of Kazakhstan, 2020
The main standard indicators (penetration at 25 °С, ductility at 25 °С, softening point, Fraas point) have been determined and analyzed in this work for bitumens of the grades BND 100-130, BND 130-200 and 21 modified bitumens. The neat bitumens of the grades BND 100-130 and BND 130-200 have been produced at Pavlodar petrochemical plant from the oil of ...
