In 1987, the Strategic Highway Research Program (SHRP) began developing a new system for specifying asphalt materials. The final product of the SHRP asphalt research program is a new system referred to as Superpave which stands for Superior Performing Asphalt Pavements. Superpave software is a computer program that assists engineers in materials selection and mix design. However, the term "Superpave" refers to more than just the computer program. Most important, it represents an improved system for specifying component materials, asphalt mixture design and analysis, and pavement performance prediction. The system includes test equipment, test methods, and criteria.
A factor that must be taken into account when considering asphalt mixture behavior is the volumetric proportions of asphalt binder and aggregate components, or more simply, asphalt mixture volumetrics. The developers of Superpave felt that the volumetric properties of asphalt mixtures were so important that a volumetric mixture design protocol was developed. This 3-hour interactive online course is the second in a series on the Superpave system. This course describes volumetric analysis of HMA (Hot Mix Asphalt), which plays a significant role in most mixture design procedures, including the Superpave system.
At the conclusion of this course, you will be able to:
Describe the component diagram approach to Superpave HMA design and the variables included in calculations
List the types of aggregate tests performed on aggregate particles
Explain the procedure for preparing a specimen for compaction
Identify the properties tested for during specimen compaction
Recognize how the properties of asphalt binders and mineral aggregates affect the overall behavior of the asphalt mixture
