  • Superpave Mixture Design Guide

    Credits: 3 PDH

    PDH Course Description:

    This document, intended as a companion to the National Asphalt Pavement Association's (NAPA) Superpave Construction Guidelines, is a guide for the (HMA) hot-mix asphalt designer to maximize the benefits of Superpave while avoiding potential problems. The Superpave design process is part of a total pavement design system. Superpave is a system of components that work together to provide a SUperior PERforming asphalt PAVEment. As traffic levels and loading conditions increase above 1 million 80-kN (18,000-lb) equivalent single-axle loads (ESALs) during a pavement's design life, some design areas are not adequately addressed by the current Superpave specifications.

    This guide discusses several issues that should be considered during the mixture design process to maximize the benefits of this method.

    Topics:

    • Introduction
    • Performance graded Binder Selection
    • Aggregate Selection
    • Mixture Design Considerations
    Performance Tests:
    • Marshall
    • Hveem
    • GTM
    • Creep
    • Wheel-Track Testers
    • Shear Testers
