This assumes that road wear and tyre wear are caused by the same mechanism, but tyre wear is presumably caused predominantly by friction, whereas road wear is at least in part (and perhaps predominantly) caused by compression, creating pot holes by causing the earth underneath to move.
It's quite noticeable (to me at least) that the areas with highest wear are usually places that have heavy vehicles (buses and lorries) braking and accelerating. Traffic lights and bus stops will often have bumps/dips that seem to demonstrate a shearing force between the road surface layers.
I have always assumed it was just due to the uneven distribution of weight by vehicles often being stationary in the same spot, so those points are subject to more compression forces than the surrounding road surface.
If it were acceleration and deceleration I’d have expected the effect to be less localised, as breaking and accelerating happens over a much longer distance.
But, I have no actual idea. It’s just probably not friction…
