The Effect of Voids in Mineral Aggregate (VMA) on Hot Mix Asphalt PavementsStatus: CompleteReport Date: 03/26/2000 Summary: This research project investigates the level of Voids in the Mineral Aggregate (VMA) in Minnesota paving projects. Researchers analyzed 10 paving projects from 1996 to determine if a VMA decrease occurred, the magnitude of the decrease, and the potential causes of the decrease. Final Deliverables: The Effect of Voids in Mineral Aggregate (VMA) on Hot Mix Asphalt Pavements (Report #2000-13) Related Materials: Related Research:
