Book excerpt: The SHRP Superpave asphalt mixture design system, with its stringent material requirements was specifically developed to produce pavements to meet the expectations of the American public. The Superpave system includes a performance graded asphalt binder system, criteria for aggregate properties, a new mix design procedure using the Superpave gyratory compactor, and refined procedures and requirements for mixture analysis. To date, the Superpave system has primarily been used on medium to high volume roadways, where funding is more readily available. Issues concerning aggregate availability and local economy have limited its use on low volume roads at the local government level. Therefore, the question is: Can the material and testing requirements of the Superpave system be economically applied at the local government level without compromising pavement performance? To answer the above question, the two key requirements of the Superpave system, material requirements and testing requirements, were evaluated.
