Aggregate Research Investigation

This research project will perform an investigation of properties related to aggregate shape, angularity, and texture; the aggregate interfacial zone and bond in concrete and asphalt mixtures; and ways of quickly identifying deleterious aggregate materials or constituents, including fine aggregate blending and grading in concrete and research on the effect of aggregate interface properties in hot-mix asphalt and warm-mix asphalt.
