Actually for ALL practical purposes....heavy trucks DO ALL
the damage to a properly engineered roadway....

The same is true for heavy aircraft vs little light ones on runways...
I know because I worked in a runway/pavement engineering
group for a few years....


My point exactly. The only difference with regard to the vehicle/highway
versus aircraft/runway comparison is in numbers. If there were no cars we'd
need far fewer multi-lane superhighways in heavily trafficked areas. We'd
still need the same heavy-duty runways if general aviation did not exist.
