I have just finished writing up sections of a report on this subject for NDOR where we looked at reduced PCB lengths an potential deflections for TL-3 and the 85th percentile impact conditions. That report is currently in draft review internally at MwRSF. It should address a lot of your questions.
The work for NDOR does not go down to TL-2 or 1, but does look at speeds around 51 mph.
As we discussed in November at the Pooled Fund meeting, if states want to look at the lower speeds, we can run some simulations under a very small year 28 project to look at the lower speeds.
