Where can we find more on this? I'm not doubting, but I can't think of why this is. It's pretty rare to find much in the physical world that uses the 4th power (Hagen–Poiseuille equation relating fluid pressure differential in a pipe - or artery - is one of the few that comes to mind)

I don't remember where but this is pretty common knowlage in urban design and transport engineering. Any textbook on road engineering should have that stuff.

From what I could find, the road damage 4th power relationship is empirically derived (in contrast to something like Hagen–Poiseuille) and the relationship is disputed by experts.

Maybe the 4th power is relationship is not mathematically proven but its certainty really fucking bad in a practical sense.
