Abstract

PURPOSE: A paving material which can be used as such or in admixture with a resin, prepared by contacting, at a specific temperature, an O2-containing gas or an O2 and O3-containing gas with an aromatics-rich fraction prepared by extracting a petroleum fraction having a specific average MW with a solvent such as furfural.
CONSTITUTION: A paving material is prepared by contacting, at 200W300°C, an O2-containing gas or an O2 and O3-containing gas with an aromatics-rich fraction prepared by extracting a petroleum fraction having an average MW of 150W850 with a solvent such as furfural, phenol or the like. Using the above oxidation process instead of thermal decomposition processes, advantages such as a markedly increased yield of resinified product, continuous operation and a low requirement of fuel (because of exothermic reaction) are obtained. The resinified product, by itself, can be used as a paving material, and also used in admixture with an epoxy resin, etc., in any proportions. Also, the resinified product does not contain carcinogenic hydrocarbons such as 3,4-benzopyrene, etc.
