Özet: In recent years, researchers and engineers investigate the effective and environmentally friendly additives for bitumen modification, thereby improving the performance characteristics of bitumen. Many additives are usually used in bituminous mixtures to reduce energy requirement by decreasing mixing and compaction temperatures of bitumen. Most bitumen shows non-Newtonian behavior at application temperatures ranges. Workability of bitumen samples depends on the proper selection of mixing and compacting temperatures. This paper is aimed to presents a laboratory evaluation of bitumen samples containing different contents of process oil. In the light of the study, base bitumen samples have been prepared with three different percentages (1%, 2% and 3%) of process oil. The prepared bitumen samples containing process oil have been subjected to Brookfield viscosity test. Mixing and compaction temperatures of bitumen samples have been determined by Brookfield viscosity test.
