TRB’s Transportation Research Record: Journal of the Transportation Research Board, No. 2028 includes of 25 papers. The papers are organized in seven parts. Part 1, General Structures, covers such topics as the effect of chloride on concrete bridge decks, a liveload distribution factor equation for girder bridges, context-sensitive design of bridges, stress-laminated bridge decks, workhorse bridges, and bridge rail repair and retrofit. Part 2, Steel Bridges, discusses two-girder bridge redundancy and repairs on steel beams. Part 3, Concrete Bridges,discusses their design, surface treatment, and reinforcing details. Part4, Dynamics and Field Testing of Bridges, discusses the topics of live loads based on weigh-in-motion data, bridge displacement estimates, impact echo data analysis, impact echo scanning of grout defects, and the analysisof highly skewed continuous steel girder bridges. Part 5, Seismic Designof Bridges, contains one paper on a reliability-based procedure for seismic design specifications. Part 6, Culverts and Hydraulic Structures, deals with the following topics: stress crack resistance of corrugated high-density polyethylene pipe; deeply buried corrugated polyvinyl chloride pipes' soil-structure interaction; pipe bursting; and interpreting AASHTO specifications. Part 7, Structural Fiber-Reinforced Polymers, is concerned with the repair and strengthening of structurally deficient piles and with the static and dynamic response to traffic loads of a fiber-reinforced polyester bridge.
