Steps to a SUPERPAVE Volumetric Mix Design
- Select asphalt and aggregates that meet SUPERPAVE specifications.
- Develop several aggregate trial blends to meet SUPERPAVE gradation requirements.
- Blend asphalt with the trial blends and "age" the mixtures in an oven.
- Compact the specimens and analyze the volumetrics of the trial blends.
- Determine the optimum trial blend to serve as the design aggregate structure.
- Compact samples of the design aggregate structure at differing amounts of asphalt binder and analyze the volumetrics to determine the design asphalt content.
