Powdery hydrophobic filler for bituminized traffic surfaces

The invention relates to a fire prevention material in loose form containing at least one material thermally insulating at temperatures up to 1100.degree. C.; at least one material which irreversibly expands at temperatures over 150.degree. C., particularly over 200.degree. C.; and at least one preferably finely divided binder, which is able to expand on heating. All the constituents of the material are waterproof and weatherproof, so that the fire prevention material can be frequently handled over long periods. It is preferably packed into incompletely filled bags.
