ACI 548.9M-08 PDF Download

ACI 548.9M-08 is a standard that specifies the requirements for Type ES (Epoxy Slurry) Polymer Overlay for Bridge and Parking Garage Decks. This type of overlay is made of a low-modulus epoxy-based slurry and a selected aggregate, which combine to create a flexible, skid-resistant, and water-resistant overlay. The purpose of this standard is to provide guidelines for the use of this type of overlay in both new construction and rehabilitation projects.

The specification covers various aspects of the overlay process, including the chemical components used, the type of aggregate required, and the storage and handling of materials. It also includes guidelines for surface preparation, ensuring that the surface is properly cleaned and prepared before the overlay is applied. The standard also specifies requirements for the surface profile, ensuring that it is suitable for the application of the overlay.

Additionally, the standard provides instructions for the mixing, placement, and finishing of the overlay. These guidelines ensure that the overlay is applied correctly and achieves the desired performance characteristics. Quality control measures are also outlined in the specification to ensure that the overlay meets the required standards and specifications.
