Oddly enough the IL-76 is one of the few planes that big that would probably have been totally fine if it had run out of paving, they're designed to not really need a properly surfaced runway. Russian runways get cracked up all to hell and back by ice, so they're extremely rough by the standards of warmer developed countries, and the planes are built with this in mind.
The end of our runways over here are very smooth for a non paved surface :)
