Abstract:

The Virginia Department of Transportation (VDOT) is interested in ways to improve asphalt mixture durability. These improvements can be accomplished through several approaches, including the use of performance-enhancing additives, such as fibers, and the incorporation of performance criteria in mixture design and acceptance. This project evaluated the initial laboratory performance of asphalt mixtures that incorporated aramid fiber additives, along with associated control mixtures not containing fibers, on VDOT pilot projects. The mixtures included traditionally designed mixtures (i.e., Superpave) and those designed to meet VDOT’s balanced mix design (BMD) criteria. The study documented production and construction details. Materials were collected during production to evaluate the mixture properties. The laboratory performance information was used to benchmark the as-constructed mixture performance and assess the potential performance benefits of fiber-modified mixtures.
