The literature found a range of damage law exponents from 1 to 12
On average, state highways…should consider using a damage law exponent of approximately 2; however, designing for the heaviest commercial vehicles operating on local low-volume roads with a lower life would need to consider a damage law exponent closer to 6.
Where bicycles typically ride, it is likely a greater discrepancy.
Unsurprisingly, it’s more complicated than that, but…
