Improving Asphalt Performance and Durability With Superpave 5

Minnesota’s harsh climate requires dense, durable asphalt to avoid frequent maintenance and replacement. Asphalt mixes as designed in the laboratory, however, don’t always perform consistently in the field. A new Superpave mix shows promise for providing cost-effective, high-performing pavements for state roadways.

Innovative Materials and Technologies for Sustainable Pavement Infrastructure

In search of enhanced pavement damage detection practices, researchers investigated two innovative additives to asphalt binders: graphite nanoplatelets and taconite concentrates. They also examined the ability of microwave energy to restore subsurface cracking.
