Abstract:

The squeeze flow tests were studied by many authors to measure the rheological properties of fluids. In the present work, experimental squeezing flow test with constant area between two parallel disks of bitumen has been investigated. The effect of the temperature, the process of preparing the sample and the gap between the discs were discussed. The obtained results were compared with the theoretical models. The behavior of bitumen depends on the ambient temperature thus, for a high temperature the consistency decreases. Also the effect of viscosity and the yield stress required for the compression test. Finally, a power law model and a biviscous fluid are used to describe the rheological behavior of the squeezing flow of pure bitumen. Recent Publications 1. P Kaushik et al.
