Abstract

The performance of an asphaltic paving material can be greatly improved when the paving material is prepared by first coating the particles of the aggregate material with a molten phenolic resin and then mixing the thus resin-coated aggregate material with asphalt and the like bituminous material. The phenolic resin is preferably modified with a phenoxy resin.
