Virginia I-66 Concrete Pavement Replacement Using Precast Concrete Pavement Systems

As part of a national initiative sponsored by the Federal Highway Administration under the Highways for LIFE (HfL) program, the Virginia Department of Transportation (VDOT) was awarded a $1 million grant to showcase and demonstrate the use of precast concrete pavement system (PCPS) technology for the replacement of concrete slabs. The I- 66 rehabilitation project in Fairfax was selected to implement this technology, and the replacement was done on two segments—a 1,020-ft length of the mainline spanning 4 lanes using precast prestressed concrete pavement (PPCP) panels and a 3,552-ft-long segment of the outside lane of the ramp leading to US-50 West using a jointed precast pavement system, Super-Slab®. The construction activities were performed between 9:00 pm and 5:00 am. The mainline was repaired using two-lane or three-lane closures, while the ramp was repaired using full ramp closures and providing detours. This report documents all details of this project, including a description of the PCPS technologies and their design, the construction staging techniques and maintenance of traffic, slab installation, and the performance evaluations and economic analysis. This report also contains other items relevant to HfL projects, including a description of HfL goals, other technology transfer activities on the project, and a detailed analysis of data to evaluate if the HfL goals were satisfied. A detailed economic analysis is included in the report to evaluate the cost-effectiveness of using the innovative technology. Individual analyses were performed for the mainline and the ramp segments. Overall, it was determined that VDOT met the HfL goals on this project and realized cost savings of about 7 percent relative to cast-in-place alternatives.
