Evaluation of VMA and other volumetric properties as criteria for the design and acceptance of superpave mixtures
Additional Document Info
Fine-graded and coarse-graded mixtures were produced at multiple VMA levels by varying the gradations and proportions for a common set of aggregates and asphalt cement. Some mixtures were purposely designed to not meet the Superpave VMA requirements, while meeting all other Superpave requirements. This paper intends to evaluate the effects of different volumetric properties such as VMA, film thickness, asphalt content, and aggregate surface area on the durability, fracture resistance, and rutting resistance of mixtures.
