This specification covers two-component epoxy resin adhesive for use as protective and or skid resistant overlays on portland cement concrete surfaces and bridge decks. Two classes of epoxy resin adhesive are provided. Classes: Class I@ bitumen modified coating is for use in protective coatings for skid resistant and/or protective overlays for cement concrete bridge decks and surfaces. It includes a recommended practice for the preparation of the concrete surface and for the application of the epoxy prime coat when required@ epoxy top coat@ glass fabric when required@ and cover material. Each system may be used as a wearing course or as a protective coating beneath an asphalt concrete pavement. Class II@ oil modified coating is for use@ with suitable aggregate@ in mortar overlays 9.5 to 12.7 mm (3/8 to 1/2 in.) thick as skid resistant and/or protective overlays for cement concrete bridge decks and surfaces. It is also suitable for application in a thin layer under asphaltic concrete as described for Class I material. It is not generally recommended as a wearing course in thin layers. The values stated in SI units are to be regarded as the standard. This standard does not purport to address all of the safety concerns@ if any@ associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
