This work uses three asphalt concrete mixtures with decreasing nominal maximum aggregate size (NMAS) to evaluate the validity of using the bending beam rheometer (BBR) to obtain flexural creep modulus of asphalt concrete mixture beams. Flexural creep modulus of asphalt pavement is an important property used to give insight into the cold property ...

Extended Creep Recovery via Oscillatory Shear and Bending Beam Rheometers
AIP Conference Proceedings, 2008Relaxation and retardation spectra are often used to describe the linear viscoelastic properties of polymer melts, asphalts, and other viscoelastic materials, since the spectra contain sufficient information from which other linear material functions can be easily calculated.

Road Materials and Pavement Design, 2014
Thermal cracking due to stress at low temperature is a major factor in roadway degradation. The purpose of this study was to measure low-temperature response of asphalt mixtures from field cores, assess the practicality of using the bending beam rheometer (BBR) to test field mixtures, compare test results to observed field performance, determine ...

Low-temperature cracking is one of the major causes of pavement distress during the winter season. Research has shown that measuring the flexural stiffness of asphalt mixture beams using a bending beam rheometer (BBR) is a good way to control the low temperature properties of asphalt mixtures.

The Development of the Bending Beam Rheometer; Basics and Critical Evaluation of the Rheometer
1995The bending beam rheometer is proposed by the Strategic Highway Research Program (SHRP) for direct measurements of the rheological properties of asphalts at the lowest pavement temperatures. The purpose of this paper is to present the basic concepts upon which the rheometer was developed, to describe the testing procedure and the important procedural ...

Role of Bending Beam Rheometer Parameters in Thermal Stress Calculations
Transportation Research Record: Journal of the Transportation Research Board, 2004The development of the Strategic Highway Research Program lowtemperature binder specifications was based on the observation that asphalt mixture creep stiffness at 2 h correlated well with instances of transverse cracking. With the correlation extended to asphalt binder stiffness and with time-temperature superposition, a maximum stiffness value was ...

The Flexural Strength of Asphalt Mixtures Using the Bending Beam Rheometer
2012Asphalt 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.

Single-Event Cracking Temperature of Asphalt Pavements Directly from Bending Beam Rheometer Data
Journal of Transportation Engineering, 2002Asphalt pavements under low temperature conditions develop transverse cracks as a result of one or a combination of three distress mechanisms: (1) single-event thermal cracking; (2) thermal fatigue...

Using The Bending Beam Rheometer For Low Temperature Testing Of Asphalt Mixtures
2016This work showed that the bending beam rheometer is a viable test to determine the low temperature performance of asphalt mixtures; it balances the rigor required of any mechanical test and the relation to field performance with the practicality of a procedure that can be easily adopted.
