On July 31 and August 1, 1982, the Oregon State Highway Division successfully placed a methyl methacrylate polymer concrete overlay on a portion of one span of a major interchange ramp in Portland, Oregon. Two proprietary polymer concretes were used in this experimental overlay project. They were Crylcon, formulate by DuPont, and Fabucrete, produced by Dural International. The main objectives of the project were (1) to evaluate the mixing and placement characteristics of the methyl methacrylate polymer concretes as overlay materials, (2) to examine the durability, skid resistance, impermeability and crack susceptability of the materials in bridge wearing course construction and (3) to evaluate the preparation of the deck surface using an airless shotblast machine.
This report describes placement and subsequent performance of two methyl methacrylate polymer concrete overlays. Performance is evaluated as to: 1) th...
Polymer overlays consist of polymer resins and aggregates and are used on bridge decks to extend service life by providing waterproofing and chloride ...
