Wisconsin Department of Transportation Flexible pavements

Flexible pavements

Research focused on improving the design, construction and performance of long-lived, quality hot mix asphalt (HMA) pavements in Wisconsin. Investigates compaction, binders, overlays, implementation of the Mechanistic Empirical Design Guide (MEPDG) and more.
