Bending beam rheometer testing of asphalt mixtures
International Journal of Pavement Engineering, 2011This paper provides a test protocol for performing creep tests on asphalt mixture beam specimens using the bending beam rheometer, and addresses the issues related to performing this test. First, a detailed sample preparation procedure is presented and the experimental data are provided to assess the consistency of this method.

Using The Bending Beam Rheometer For Low Temperature Testing Of Asphalt Mixtures
, 2016 This 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.

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 ...

, 2018 n northern US and Europe thermal cracking is a dominant distress for asphalt pavements. For this reason, a robust and reliable characterization method of asphalt binder at low temperature is fundamental for correctly selecting the right material and for design of asphalt mixtures which can provide satisfactory long-term performance.

Abstract The low-temperature rheology of bituminous binders is of great interest because low-temperature cracking is one of the primary failure modes of asphaltic pavements in cold-climate region. Low temperature binder characterization/grading has been primarily conducted using the bending beam rheometer (BBR) which requires much binder for specimen

Asphalt Mixture Beams Used in Bending Beam Rheometer for Quality Control
Transportation Research Record: Journal of the Transportation Research Board, 2012This paper introduces the use of asphalt mixture beams in the bending beam rheometer (BBR) for quality control with a project in Utah as a case study. A good solution for quality control, the BBR test can be performed by materials laboratory staff at highway agencies and private materials laboratories because it is reasonably priced, is rugged-tested ...

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.

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 ...
