Abstract
Asphaltic materials (e.g., asphalt, bitumen, or pitch) are increased in flame-resistance and improved in other useful properties by use of a latent catalyst mixture which reacts upon heating to catalyze oxidation of the asphaltic material. The catalyst comprises halogenated organic compound which decomposes and releases halogen upon heating and an iron-containing compound adapted to react with the released halogen to form iron halide.
