| Abstract | As a part of the Federal Highway Administration (FHWA) Highways for LIFE initiative, a Federal grant of $2,000,000 was provided to the New Hampshire Department of Transportation (NHDOT) for this project, which was in addition to FHWA’s 80 percent contribution under the Federal-aid highway funding program. The Auburn-Candia project involved resurfacing of a 14.8-mile segment (7.4 miles eastbound and 7.4 miles westbound) of NH Route 101, from the Manchester-Auburn line to the Auburn-Candia line. The project scope primarily included a mill-and-fill operation with a 2-inch intermediate course placed in the two travel lanes, followed by a 1.5-inch wearing course installed over both lanes. Additional work included guardrail upgrade, roadway drainage structures adjustment, and pavement work on the Exit 2 and Exit 3 ramps. The resurfaced highway segment, last paved under the 1999/2000 Federal Resurfacing Program, includes three bridges in each direction. This project incorporated six innovations: recycled asphalt pavement, warm mix asphalt technology, asphalt-rubber wearing surface course, highly modified asphalt wearing surface course, Safety Edge pavement, and smart work zone techniques. The project was let on May 17, 2012, and the construction was completed in October 2013. The NHDOT’s total construction costs on this project, including mobilization and traffic control, were $13.4 million. Although the project could not be evaluated for all of the Highways for LIFE performance goals, NHDOT gained valuable insight into the innovative materials and techniques—both those that were successful and those that need further evaluation. In support of NHDOT’s “green” initiatives, the lessons learned from this project may promote the use of recycled materials, such as the milled asphalt material and the ground rubber tires, while providing pavements with extended service life and reduced tire pavement noise. |
