Design-Construction of a Precast, Prestressed Concrete Pavement for Interstate 10, El Monte, California

This article reports on a precast, prestressed concrete pavement demonstration project on Interstate 10 in El Monte, California; the project was completed by the California Department of Transportation (CALTRANS) in April 2004. The project was designed to permit CALTRANS to evaluate the viability of precast concrete pavements for rapid pavement construction and rehabilitation, as well as to familiarize local contractors with this construction technique. The bulk of the construction of the 248 ft (76 m) section of precast, prestressed concrete pavement was completed at night, when lane closures were permitted on I-10. The authors note that construction is often limited to seven-hour overnight construction windows for pavement reconstruction in urban areas, thus the precast or modular pavement construction is becoming more necessary. To maximize the pavement's performance, the precast concrete panels were pretensioned in the transverse direction during fabrication and post-tensioned in the longitudinal direction after installation. The authors conclude that precast, prestressed concrete has a proven track record in the bridge and commercial building industries and it is only logical that it be used for providing a rapid construction solution. In addition, it provides a solution with excellent long-term performance. Additional demonstration projects are underway, including the use of precast, prestressed concrete pavements for applications such as weigh-in motion (Texas), replacement of original Interstate-era jointed reinforced concrete pavement (Missouri), and replacement of pavement under bridge overpasses to increase overhead clearance (Indiana).
