Any pavement that was in that area was totally burnt off, while any cement—sidewalks and what have you—is burnt to the point where, when you walk on it, it's more like walking on a thin layer of sand than actually walking on cement.
L'asphalte a complètement brûlé, et le béton — les trottoirs et tout le reste — donne l'impression de n'être plus qu'une mince couche de sable lorsqu'on marche dessus.
