FOND DU LAC COUNTY, WI — A recently completed rural highway reconstruction project in Wisconsin has resulted in improved durability, a smoother ride, and an extended roadway life, thanks to an innovative approach to asphalt specification requirements.

Working with the Wisconsin Department of Transportation and Northeast Asphalt, Benesch construction engineers developed a methodology for using two asphalt specifications in tandem: (1) longitudinal joint density and 2) Percent Within limits (PWL).

The resulting success of the approach is setting a new standard for roadway construction in Wisconsin.

Asphalt Pro Magazine interviewed members of the Benesch Team, the contractor and WisDOT to learn more about the STH-23 reconstruction project and what made their approach so successful.
