Investigation, Dynamic Testing, and Evaluation of Guardrail Posts for Use in Transitions between Temporary Concrete Barrier and Guardrail

Temporary concrete barriers (TCBs) are connected and transitioned to many types of barriers. Unfortunately, the only transitions previously developed have been between TCBs and safety shaped concrete barriers and TCBs and permanent concrete median barriers. Transitions between TCBs and other common barrier types, such as guardrail, have typically not been full-scale crash tested and may pose a serious hazard to motorists during an impact. The Midwest Roadside Safety Facility (MwRSF) has an existing project that consists of developing a transition between TCBs and the Midwest Guardrail System (MGS). That project has funding to identify and quantify the most pressing TCB to guardrail transition needs and for concept development with LS-DYNA computer simulation. However, further research is needed to evaluate the performance of typical post types and sizes that could potentially be utilized during the concept development. Therefore, this project seeks to supplement the concept development and simulation of transitions between TCBs and the MGS through dynamic post testing.
