In the early 1990s a PW 4060 powered 767-300 was damaged by flying asphalt pavement during an engine run-up at Schiphol-East. The damage to the aft fuselage and horizontal stabilizer was extensive and a new stabilizer was even flown in from Seattle and exchanged for the damaged one. In this case it was evidently not from pavement material thrown up by the landing gear, as the aircraft was stationary.

On June 4th, 1989, a CF6-50 powered 747-200 was a decidedly uncommon replacement for a DC-10 to Heraklion Airport, Crete, Greece. Landing as well as take-off were on 09, necessitating for take-off a backtrack towards the otherwise generally overflown western runway end with a 180 deg turn on the turning pan.
The airport was normally only used by smaller aircraft types with less than 4 engines. After take-off a huge rising column of dust was observed, a kind of dirty thermal, and the next airplane landing reported a lot of loose pavement material and damaged runway lights. The runway was subsequently closed for some time, and a shorter crosswind runway was opened for those who could accept it instead of diverting.

The 747 was not scheduled there again. But no airframe damage was reported (as far as I know). In this case, the outboard engines may have swept up loose stuff from the pavement edges, i.e. outside the path of the stabilizer, and the inner engines, well, those were blowing on ground frequented by two- and three-holers!
