Long-Life Asphalt Pavement Saves Caltrans $19 million, Study Finds
A recent case study by the Asphalt Pavement Alliance has found that Caltrans’ eighth long-life/perpetual pavement (L-L/PP) project, located on Interstate 5 in Sacramento, saved Caltrans $19 million in initial construction costs.
Long-life Asphalt Pavement designs are expected to last for 40 or more years with minimal maintenance.
The $270 Million project was constructed in a joint venture by Granite Construction and Teichert and aimed to renovate a 15.3 mile stretch of aged concrete pavement in Sacramento County, Calif.
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.
AsphaltPro covered the project in depth in our May 2022 issue.
“This example of value engineering on this recently completed Caltrans I-5 project is a demonstration of contractor ingenuity and innovation and agency partnering resulting in substantial project cost savings, reduced construction time, and a Long-Life/Perpetual Pavement project,” the case study concluded.
