Things like load bearing capacity of the pavement. Aircraft not only
need to be supported by the runway, but also by the taxiways and
ramps. Large aircraft especially can sink through the pavement at high
gross weights. "Footprint" weight is important, considering max gross
weights as well as size and number of tires on the landing gear.

Back in late 1957 I delivered their first F86D to the Kelly TX ANG to
replace their F80s. Upon deplaning we discovered the Dog's main gear
had sunk not into but through the asphalt of their parking ramp. . . .
