A function of asphalt emulsions is often to rejuvenate the surface of an aged asphalt concrete roadway. However, it is unclear as to the effectiveness of different types of asphalt emulsions, as most current testing is empirical and does not give an indication of field performance.

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,

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.

Recently, use of pavement preservation technologies, such as bituminous seal treatments, has increased. Seal treatments are often used to rejuvenate aged asphalt pavements and can decrease permeability and retard oxidation, cracking, and raveling. Many factors affect rejuvenation, and current specifications governing how rejuvenation is characterized ...

Thermal Cracking Potential of High RAP-WMA Evaluated With Bending Beam Rheometer Mixture Beam Test
Journal of Testing and Evaluation, 2013Abstract In recent years, increasing cost of the raw materials for asphalt paving has generated interest in using greater quantities of reclaimed asphalt pavement (RAP). During the same period, development of warm-mix asphalt (WMA) technology has allowed use of lower production temperatures that can reduce the amount of short-term aging ...

Investigation of asphalt mixture strength at low temperatures with the bending beam rheometer
Road Materials and Pavement Design, 2014A 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
