Transition for Anchored Temporary Concrete Barrier System ...

Texas AM Transportation Institute (TTI) recently developed a pinned-down F-shape temporary concrete barrier system that provides limited deflection and can be used on 4-inch thick asphalt pavement. In some applications, it is possible that a non-anchored free-standing barrier segment may be used with the anchored section.

Abstract. The objective of this research was to test the free-standing and pinned down temporary concrete barrier, used in previously developed restrained TCB design, in accordance with the MASH testing criteria.MASH tests 3-10 and 3-11 were to be performed on the free-standing TCB. Due to budgetary constraints, only test 3-11 was performed on the restrained TCB.
