We are not aware of any testing of overlapped portable concrete barrier. Note that this practice is the subject of a recently initiated project of the Roadside Safety Pooled Fund. It is entitled “Guidelines for Overlapping Precast Concrete Portable Barriers” (T1969-AL). This project is still in the early stages, with Task 1 being a review of current practice to determine variables that should be included in the subsequent evaluation through finite element simulation analysis and MASH crash testing. All Pooled Fund members should receive a related survey this month.

Thank you Roger for your answer. I remembered seeing something about this at the recent annual meeting but couldn’t find the project. I look forward to the results of the project.
