Has there been any testing or evaluation of portable
concrete barrier, specifically the PCB developed by MwRSF, under MASH where it
goes from a freestanding to anchored configuration?   The detail
below shows what FDOT has been doing for several years prior to MASH

I believe that we did the original development of the NCHRP Report 350 roadside transition from free-standing to anchored PCB with Florida’s help under Charles Boyd. It used the pin configuration shown below and thrie beam.




The roadside version has not be re-evaluated under MASH TL-3. We did develop a median version of the transition through the Midwest Pooled Fund that was tested to MASH. See below.




We are also currently evaluating the use of the bolted tie-down for concrete surfaces and the asphalt tie-down for the F-shape PCB under MASH TL-3 in cooperation with Wisconsin. The bolted tie-down met MASH TL-3 and the asphalt pin tie-down is being constructed currently and should get tested this fall.
