Abstract:Wacker Drive in Chicago is a double-deck viaduct constructed along the Chicago River. Because of severe moisture-driven deterioration, the section of the elevated road between Randolph Street and Michigan Avenue are being reconstructed using a post-tensioned slab produced of high-performance concrete topped with a replaceable latex-modified concrete overlay. In order to verify the adequacy of the road way design, a full scale prototype was built and a test program was executed to evaluate the structural performance of the superstructure and its elements. Specifically, the following structural performance characteristics were evaluated: Positive and negative flexural strength Shear strength Live load stress range in concrete and post tensioning tendons Cracking at service load, overload and ultimate load Deflection at service load, overload and ultimate load Overlay bond strength and interaction between overlay and substrate Dynamic response This paper describes the prototype construction, analysis and testing.
