• Abstract:
  Temporary concrete barrier (TCB) systems are utilized in many situations, including placement adjacent to vertical drop-offs. ; Free-standing TCB systems are known to have relatively large deflections when impacted, which may be undesirable when dealing with ; limited space behind the barrier, such as on a bridge deck or with limited lane width in front of the barrier system. In order to allow TCB ; systems to be used in space-restricted locations, a variety of TCB stiffening options have been tested, including beam stiffening and ; pinning the barriers to the pavement. These pavement-pinning procedures have been considered time-consuming and may pose undue risk ; to work-zone personnel who are anchoring the barrier on the traffic-side face. Thus, a means of reducing TCB deflections while reducing ; risk to workers was deemed necessary. ; The primary research objectives were to evaluate the potential for reducing barrier deflections through the use of pinning every ; barrier section on the back-side toe of the New York State’s New Jersey-shape TCBs and evaluate the barrier system according to the ; Test Level 3 (TL-3) criteria set forth in the Manual for Assessing Safety Hardware (MASH). The research study included one full-scale ; vehicle crash test with a Dodge Quad Cab pickup truck. Four 15½-in. (394-mm) long, vertical steel pins were placed through holes on the ; back-side toe of each barrier section and inserted into drilled holes within the rigid concrete surface. Following the successful redirection ; of the pickup truck, the safety performance of the pinned anchoring system was determined to be acceptable according to the TL-3 ; evaluation criteria specified in MASH using the 2270P vehicle.
