Generally they are concrete, sometimes parking areas and taxi ways are paved. It doesn't matter insofar as burning because while pure asphalt will burn, asphalt that has been made into pavement generally will not because of the added sand and fine gravel.So runway’s are only concrete and not asphalt?
When it does burn a bit it's because fuel was on fire on top of it, and it's only at the end of the fire if it gets hot enough that the paving will burn a little bit. It will not sustain flame on its own.
