  author={Katica Serti{\'c}-Bionda and M. Zaic-Kubatovic},
The physical and chemical characteristics of road- grade bitumens type BIT-200 and BIT-60, produced in a laboratory unit for oxidation of vacuum resid from REB and Iraq crude,were determined, and the applicability of the functional viscosity-temperature dependence in the temperature range from 60 °C to 135 °C was tested. Two function dependancies were tested: In η = a+b/T 4 (1), and Inin η=a+b/T (2). With application of the first dependence better correspondence between measured and calculated… CONTINUE READING
