Materials and Research SectionUS Transportation CollectionThis report documents the construction and performance of two thin polymer concrete (with polyester/styrene resins) bridge deck overlays. The overlays were constructed in Biggs and Maupin, Oregon in June 1993. Construction of the overlays was less than ideal. The polymer concrete on both bridges has since delaminated resulting in blocks of loose material. Both overlays are scheduled for removal in the fall of 1995. Several aspects of the construction provided information that should be considered during construction of future concrete overlays
