How to consistently collect rheological data for bitumen in a Dynamic Shear Rheometer? [PDF]

open access: yesSN Applied Sciences, 2018
The measurement of rheological properties of binders is dependent on various factors such as time, temperature as well as on aging. The common causes of erroneous measurements that occur during the rheological tests are related to the sample conditioning and sample loading.
