The FHWA has released its, “Precast Concrete Pavement Implementation by U.S. Highway Agencies” (FHWA-HIF-19-011), a seven-page tech brief that provides an overview of precast concrete pavement (PCP) technology and other information about its use throughout the United States.
A review of projects constructed in the U.S., as well as field testing of selected projects “indicate that sufficient advances have been made to reliably design and construct PCP systems to achieve five key attributes of successful pavements,” the tech brief says. The five attributes are: constructability; concrete durability; load transfer at joints; panel support; and performance/efficiency.
The tech brief goes on to say, “The use of both jointed and post-tensioned PCP systems systems has advanced during the last decade due to a combination of work sponsored by the FHWA, projects constructed by highway agencies, and innovations by the construction industry.”
The tech brief provides details about PCP projects in 29 states including: AL, CA, CO, CT, DE, DC, FL, GA, HI, IL, IN, and IA. The list also includes KS, LA, MI, MN, MO, NV, NJ, NY, OR, PA, RI, TX, UT, VT, VA, WV, and WI.
The author of the revised tech brief is Shiraz Tayabji, Ph.D., P.E. Tayabji and Wouter Brink, Ph.D. authored the previous version. The 2019 version supercedes the 2015 version.
