- beerandt 7y agoYou need to approach or exceed a roads per-axel weight limit to do any damage or serious wear. Trucks and permit loads are pretty much the only things that get close. Beyond the elastic limit, damage is an exponential function of the pavement loading, but only once that certain minimum psf is hit. For the majority of a highway's loading curve, the damage-per-force is essentially nil. Plastic deformation and serious fatigue only start as you approach the design limits. It's 99%+ because cars don't do any real wear or damage to pavement from typical use.
- cameldrv 7y agoA semi is doing 400x as much damage as essentially the heaviest personal vehicle driving. For a more typical car at 4000 lbs (2000 lbs per axle), the semi does 6000x as much damage. If semis are 2% of all traffic (true in my observation), they're doing over 99% of the damage to roads. It makes no sense to care about road damage at all from any vehicle other than a heavy truck.
