Evaluating the Representative Volume Element of Asphalt Concrete Mixture Beams for Testing in the Bending Beam Rheometer

2013
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 ...

Assessment of Various Approaches to Determining Binder Bending Beam Rheometer Low Temperature Specification Parameters from Dynamic Shear Rheometer Test

Asphalt Paving Technology, 2020
The current asphalt binder performance grading system employs Dynamic Shear Rheometer (DSR) testing to determine high and intermediate temperature rheological properties. In recent years, the ability to measure DSR instrument compliance has allowed researchers to reliably measure low temperature binder properties as well.

Artificial neural network modeling of the modified hot mix asphalt stiffness using Bending Beam Rheometer

Materials Today: Proceedings, 2021
Abstract Tensile related cracking for asphalt mixtures is one of the major distresses for asphaltic pavements. Many of the pavements distortions were a straight and non-straight wards results for heterogeneity of values of the stiffness in the local produced hot asphalt mixes.

Repeatability and Reproducibility of Low-Temperature Testing of Asphalt Mixtures Using a Modified Bending Beam Rheometer

Cold Regions Engineering 2015, 2015
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.

Use of the bending beam rheometer as a low-temperature performance test for asphalt mixtures

2018
The Bending Beam Rheometer (BBR) test is a recently developed test that is used to determine low-temperature behavior of asphalt mixtures. By knowing the low-temperature behavior, transverse cracking can be effectively predicted. Transverse cracking is a major cause of distress in wintertime and degrades the pavement structure. Significant research has

Single-Event Cracking Temperature of Asphalt Pavements Directly from Bending Beam Rheometer Data

Journal of Transportation Engineering, 2002
Asphalt 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...

Introduction of the bending beam rheometer at EMPA

1995
This study was put together to introduce the Bending Beam Rheometer (BBR) system at EMPA. The BBR is a rheometrical testing device dealing with a steady load deflection to gain properties dealing with bituminous material strength at temperatures to -35 °C.

Development of low-temperature performance specifications for asphalt pavements using the bending beam rheometer

2013
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 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 whether a ...

Exploring the Low-Temperature Performance of Innovative Sealant-Treated Asphalt Surfaces Using the Bending Beam Rheometer

Journal of Testing and Evaluation
ABSTRACT Low-temperature transverse cracking is a major cause of distress in flexible pavements, emphasizing the need for effective preservation strategies. Sealant materials play a crucial role in mitigating this deterioration. With aging and oxidation, pavements become increasingly prone to cracking.
