13、e Slurry) Polymer Overlays for Bridgeand Parking Garage DecksAn ACI StandardReported by ACI Committee 548ACI 548.10-10This Specification covers methyl methacrylate slurry (MMS) overlays forbridge and parking garage decks. Type MMS polymer overlay incorporatesmethyl methacrylate-based primer, binder,
14、 and top coat with selected fillerand aggregate to produce a flexible, skid-resistant, and water-resistant slurryoverlay. The overlay is used for both new construction and rehabilitation.The overlay is placed by applying the polymer slurry system to the surfaceand broadcasting aggregate. This Specif
15、ication includes requirements forchemical components, aggregates, storage and handling, surface preparation,surface profile, mixing, placement, finishing, and quality control.The materials, processes, quality control measures, and inspectionsdescribed in this document should be tested, monitored, or
