ACI 548.8-07

This Specification covers epoxy multi-layer (EM) polymer overlays for bridge and parking garage decks. Type EM polymer overlays incorporate a low-modulus epoxy binder and selected aggregate to produce a flexible, skid-resistant, and waterproof overlay. The overlay may be used for both new construction and rehabilitation. The overlay is placed by applying the neat epoxy binder to the surface and broadcasting aggregate. This Specification includes requirements for chemical components, aggregates, storage and handling, surface preparation, surface profile, mixing, placement, and finishing.
