Specification for Type EM (Epoxy Multi-Layer) Polymer Overlay for Bridge and Parking Garage Decks

Abstract

This Specification covers materials and procedures for constructing a multi-layer, low-permeability epoxy polymer (Type EM) overlay for new construction and rehabilitation of bridge and parking garage decks, using mechanical, semi-automated, and fully-automated methods.

Type EM polymer overlay incorporates a low-modulus, epoxy binder and selected aggregate to produce a flexible, skidresistant, and low-permeability overlay.

This Specification includes requirements for epoxy resin components, aggregates, storage and handling, surface preparation, surface profile, mixing, placement, quality control, and quality assurance.

This Specification supplements the contract documents and provides requirements for the contractor.

This Specification governs for construction within its scope, except the contract documents govern if there is a conflict.

This Specification governs if there is a conflict with its referenced standards.

The Contractor is permitted to submit written alternatives to any provisions in the Specification.

Do not use this Specification in conjunction with ACI 301 or ACI 350.5.

Ignore provisions of the Specification that are not applicable to the Work.

Values in this Specification are stated in inch-pound units.

A companion specification in SI units is also available.

The Notes to the Specifier are not part of this Specification
