Utah Department of Transportation’s $43 million seven-mile repaving project along I-80 east of Park City improved safety and mobility to ensure the uninterrupted flow of products and commerce through one of the nation’s busiest east-west interstates. For the first time in Utah, crews used a 100 percent cement-treated asphalt base into their paving operations and used recycled asphalt from the existing roadway to provide a strong base for this new concrete road. They also used a wireless system in which pavers run on robotics, without the guide wires used on traditional systems. Designers loaded 3D models of the roadway into the paver’s computer to control alignments and improve pavement quality. This innovative process process was 10-15 percent faster than traditional paving, increased durability and reduced overall traffic impacts duration.
