Develop Guidelines for Inspection, Repair, and Use of Portable Concrete Barrier

The Manual for Assessing Safety Hardware (MASH) Implementation agreement allows State Transportation Agencies to continue the use of Portable Concrete Barriers (PCBs) manufactured on or before December 31, 2019 and successfully tested to NCHRP Report 350 or the 2009 edition of MASH, throughout their normal service life. Damage to the precast barriers can occur in transit, in storage, or due to vehicular impact. Often damage to the connections occurs, cracks in the barrier, corners broken and many other forms of damage can be sustained by the barrier. No federal guidance, however, has been developed to determine life expectancy for PCBs. There is a need to develop a guideline addressing the type and extent of barrier damage that would constitute replacement of the segment. To meet the research objective, the research team will document best practices with respect to management of repairing or replacing PCB segments and utilize a combination of engineering evaluation, dynamic component testing and full-scale crash testing to develop guidelines to assist in developing a process to determine the useful service life. Defining the service life of PCBs is important to reduce the risk of inferior unsafe barriers being used on Texas roadways.
