Current Industry Practices and Opportunities to Reduce Future Emissions

When the most intense storm in Lee County history washed away sections of the Sanibel Island causeway, access to repairs and resources were cutoff. A joint venture between Superior Construction & de Moya Group restored the roadway in record time.

Central Illinois’ Piatt County lies just west of Champaign-Urbana. A small community with a total population of about 17,000, Piatt recently stepped into the limelight of road-building innovation
when it won a prestigious Perpetual Pavement Award (PPA) — only the second U.S. local public agency road project to ever receive such recognition. PPAs are awarded by the Asphalt Pavement Alliance (APA) to road projects that have moved away from traditional construction methods to Perpetual Pavement design standards.

This $270 Million project, constructed in a joint venture by Granite Construction and Teichert, is the renovation of a 15.3 mile stretch of aged concrete pavement in Sacramento County, CA. The section runs from downtown Sacramento (American River Bridge) to 1.1 miles south of Elk Grove. Besides converting the existing pavement to a L-L/PP, other aspects, such as widened lanes, added HOV lanes, bridge work, median barrier, pedestrian crossing, and information systems were part of the contract. Both full-depth (FD) and the crack, seat, and overlay (CS&O) were utilized to create perpetual pavements. 

The Iowa Department of Transportation constructed an innovative asphalt pavement project featuring perpetual pavement long-life design concepts in 2016. The award-winning project, located on a 3.5- mile stretch of State Highway 100 near Cedar Rapids, provided reduced life-cycle costs and reduced environmental impacts as compared to conventional design approaches.

Many airport runways, taxiways, and aprons are constructed of asphalt pavements. The performance of the surface is critical to the safe operation of the aircraft and asphalt's speed of construction makes it an ideal choice for rehabilitation of busy aviation facilities. With careful design, asphalt can withstand the high demands of airfield sites.
