The Wisconsin asphalt-paving industry is undertaking several initiatives to continually improve the construction of asphalt pavements through a quality management program and two piloted specifications. The quality management program provides contractors and the Wisconsin Department of Transportation (WisDOT) with structured process control and quality assurance for hot-mix asphalt paving projects.

A statistically based nuclear-density specification will be piloted in 1996 to provide density-process control and quality assurance using nuclear density gauges. These initiatives are moving toward the goal of performance-based construction and are possible with a commitment to quality from WisDOT and contractors, including members of the Wisconsin Asphalt Pavement Association. Members of the industry are combining resources and restr...
