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.
