Development of a Plan for Compliance with NCHRP 350 for Temporary Concrete Barriers

The Federal Highway Administration (FHWA) has mandated that TCBs used on federally funded projects on the National Highway System (NHS) advertised after October 1, 2002 shall meet the requirements of NCHRP 350. The State’s present TCB system design is not approved as meeting the NCHRP 350 requirements, and even with modifications it is not likely to meet those standards. ADOT and Arizona industry partners are to evaluate many key factors in the Department’s effort to develop an NCHRP 350 compliance plan for TCB. Arizona intends to adopt the most valid non-proprietary TCB design, out of already approved designs, for future use in Arizona.
