Performance Related Specifications for Asphalt Pavements: Applications of Bending Beam Rheometer (BBR) and Semi-Circular Bending (SCB) Tests

Adoption of any pavement performance specification requires an understanding of all aspects of mixture design including factors like how the new requirement will affect the binder content, how the new requirement will affect the durability of the pavement, how the requirement will affect current rutting tests (i.e., Hamburg WTD results), and how these two tests complement each other. This research will attempt to answer these questions by evaluating selected asphalt mixtures for low temperature cracking, intermediate temperature fracture energy, and high temperature deformation (rutting) to ensure that the addition of a low temperature test will not adversely affect the high temperature performance or the durability of pavements. This will allow for better optimization of mixes and reduction of poor performance potential of Utah Department of Transportation's (UDOT’s) largest asset.
