>Given that road wear grows to the fourth power
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)
- panick21_ 3y agoI 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.
- bumby 3y agoFrom 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.
- panick21_ 3y agoMaybe the 4th power is relationship is not mathematically proven but its certainty really fucking bad in a practical sense.
