ABSTRACT

Empirical methods of designing asphalt mixtures leave much room for improvement to fully utilize the potential of source materials. This approach is currently being replaced by a mechanistic-empirical approach, but only to a limited degree. In this regard, dissipating asphalt mixtures offers not only a new material, but a distinctly new approach to the design and grading of asphalt mixtures. These new dissipating asphalt mixtures have been developed for their greater resistance to the development of permanent deformations and cracks, as they dissipate the pressure from traffic and climatic influences to other forms of energy. Both conventional and innovative laboratory analyses of individual component properties are used for their development, including analyses of their mutual interactions within the asphalt mixture. This article presents the results as measured in a laboratory, including various dissipating asphalt mixtures comparison to conventionally produced mixtures.
