DescriptionThe current asphalt binder performance grading system requires the use of multiple pieces of testing equipment to determine high, intermediate and low temperature properties. To properly grade an asphalt binder, numerous hours of labor must be expended to run through all of the required aging and testing. Additionally when creating master curves to compare stiffness and phase angle with respect to frequency, multiple pieces of equipment are required. This not only creates inefficiencies with respect to time and money, but also brings an approximation into the data as opposed to a direct reading. In order to forensically evaluate asphalt binders, the asphalt must be extracted and recovered from roadway cores. During the extraction/ recovery process the amount of binder required results in coring a considerable amount of the road in question as well as running through an expensive and time consuming chemically intensive process to extract the bituminous material. This paper investigates the potential of the 4 mm Dynamic Shear Rheometer geometry and its potential applications in evaluating binder properties for all failure mechanisms without the need for additional equipment and reducing the amount of asphalt required.
