ABSTRACT:ÿÿ Processes for the treatment of asphalt pavements such as asphalt roads and sidewalks to make them more resistant to corrosion, that is, resistant to deterioration and disintegration, which comprises applying to the asphalt pavement a liquid composition consisting essentially of finely divided particles of a solid substance having a hardness between 8.5 and 9.5 on the Moh scale, such as a mixture of particles of silicon carbide and electrofused alumina, dispersed in a vehicle consisting of one or more organic synthetic resins and one or more solvents for the resin.

EXEMPLARY CLAIM(s): Show all 12 claims
What is claimed as new and desired to be protected by Letters Patent is set forth in the appended claims:
ÿÿÿÿ1. A process for improving the resistance of the surface of an asphalt pavement to corrosion, deterioration and disintegration which consisting of the step of applying directly to the pavement a liquid composition consisting of at least one cured resin, a solvent for said resin and having dispersed therein finely divided particles of solid inorganic substances having a hardness between about 8.5 and 9.5 on the Mohs scale, said composition being applied to the pavement in a quantity sufficient to form a coating on the pavement which is firmly anchored thereto due to the impregnation of the pavement by the resin.
ÿÿÿÿ7. A process according to claim 1, wherein said resin is at least one member selected from the group consisting of phenol-formaldehyde resins, epoxy-modified phenol-formaldehyde resins, poly(methylmethacrylate) resins, polyester resins, poly(vinyl chloride) resins and polystyrene resins.
