Performance-based mix design
Performance-based mix design
High content recycling, warm mix asphalt, and other advanced technologies are changing asphalt mixtures beyond the narrow margins where conventional volumetric asphalt mix design holds true.
Performance-based tests can be used to characterize asphalt mixtures regardless of materials and technologies in use, thus allowing to extend pavement life cycle, save costs and minimize environmental footprint.
Literature summary on performance-based design
Literature summary on performance-based design
Through an extensive literature review the effects of properties and proportions of binder, aggregates, modifiers and selected advanced technologies on key mixture performance-based parameters like cracking, rutting, stiffness, workability and moisture resistance are systematically summarized. A table indicating the expected performance-based test result trends is provided to aid in optimization of mixture composition. The information is intended to be the first source for a mix designer when deciding on means to improve performance or troubleshoot the failures of an asphalt mixture. Full article can be accessed here.
