Greetings,
Are you aware of any TL-5 crash tests that have been performed on 42” high non-reinforced concrete barrier (either Jersey or F-shape)?
There has been testing on the Ontario Tall Wall. However, we do not promote its use do to the lack of reinforcement, the formation of shrinkage and temperature cracks over time, and the shifting ballast observed in the testing program which potentially may have reduced the impact loading. This barrier was listed in the prior versions of the Roadside Design Guide.
