Phạm vi áp dụng / Scope of standard

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.
