Investigation of asphalt mixture strength at low temperatures with the bending beam rheometer

open access: yesRoad Materials and Pavement Design, 2014
A new strength test method for asphalt mixture at low temperatures is presented in this paper. The method uses a modified bending beam Rheometer (BBR), capable of applying loads at different rates. Two major factors, that can significantly affect strength, were analysed: cooling medium and specimen size. Similar strength values were obtained in air and

Investigation on the cooling medium effect in the characterization of asphalt binder with the bending beam rheometer (BBR)

open access: yesCanadian Journal of Civil Engineering, 2018
In this paper, the possibility of using air as an alternative cooling medium for testing asphalt binder in the bending beam rheometer (BBR) is considered and evaluated. For this purpose, five asphalt binders were characterized with the BBR; creep stiffness, m-value, performance grade (PG), thermal stress, and critical cracking temperature were ...

The Flexural Strength of Asphalt Mixtures Using the Bending Beam Rheometer

open access: yes, 2012
Asphalt mixture creep stiffness and strength are needed in the low temperature algorithm of the AASHTO Mechanistic Empirical Pavement Design Guide to predict low temperature performance. A procedure for obtaining creep stiffness by testing thin mixture beams with a Bending Beam Rheometer was previously developed at University of Minnesota.
