Description
Summary:Three main rheological properties of petroleum bitumens were investigated with the aim of developing a suitable model for the determination of a quality parameter. Two mathematical models have been proposed; one relates softening point to penetration while the other correlates softening point and viscosity. Comparison of the two models with another previously developed model shows that the softening point/viscosity model produces the best results. It also has a great advantage since viscosity can be more accurately measured than penetration and on-line quality control can be effected through viscosity within a few seconds The results of this investigation justify the objective of finding a system of parameters relating the rheological characteristics of bitumens with the generally accepted criteria.
