Rheological performance evaluation of activated carbon powder modified asphalt based on TOPSIS method

Case Studies in Construction Materials
In this study activated carbon powder (ACP) was incorporated into asphalt to substitute a portion of the conventional filler (mineral powder, MP). The dynamic modulus at elevated temperatures, temperature-dependent viscosity sensitivity, low-temperature ...

Study on the influence of anti stripping agent on the rheological properties of asphalt at high and low temperatures.

PLoS ONE
In order to compare the effects of different anti stripping agents on the rheological properties of asphalt at high and low temperatures, four typical anti stripping agents, amine PA-1, non amine XT-2, hydrated lime, and cement, were selected.

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

Road 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)

Canadian 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 ...
