LynnKoppa, RogerTexas Transportation InstituteUnited States. Federal Highway AdministrationTurner-Fairbank Highway Research CenterFederal Highway AdministrationThis study addressed the design and performance of longitudinal barriers for construction zones. The strengths of various connections for portable concrete median barriers (PCB) are analyzed and theoretical treatments of behavior of the PCB during a collision are presented. These analyses along with cost data and crash test information are used to develop a barrier performance rating and selection system. Crash tests on a non-deflecting PCB with various types and sizes of vehicles are reported.79
