PCB Transition from Freestanding to Anchored

Question
State FL
Description Text

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
considerations.

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.
