Abstract:

Three primary products will be delivered at completion of the Asphalt Research Program of the Strategic Highway Research Program, a performance based asphalt binder specification, a performance based asphalt mixture specification and a mixture design and analysis system. SUPERPAVE software is a mix design software package which integrates the SHRP products and provides the mix designer with tools and information needed to perform a mix design with SHRP specifications. SUPERPAVE software encompasses all phases of mixture design from selection of raw materials, aggregates and asphalt binder, volumetric mixture design, performance based testing and performance prediction. Also, SUPERPAVE software is designed for field verification of the mixture and quality control testing. This paper provides an overview of SUPERPAVE software capabilities. The methodology of SUPERPAVE mixture design is discussed but only to the extent necessary for understanding of the software capabilities. This paper has tried to highlight pertinent features of the SUPERPAVE software to provide the reader with an appreciation of the capabilities of the software.
