Project Details

Project Abstract: 

The research will utilize flexible wall, triaxial consolidation of hot-mix asphalt (HMA) job mix formulas as a more fundamental measure of compaction rather than Superpave gyratory compaction to rank the compactability. The ranking will be paired with an on-the-market Aggregate Imaging System, which now has an established American Association of State Highway and Transportation Officials provisional protocol and basic practical volumetric measures.

Goals

Address the gaps in the calibration inputs for previously completed "Modeling of Hot-Mix Asphalt Compaction: A Thermodynamics-Based Compressible Viscoelastic Model."
