Abstract:

South Carolina has over 9,000 bridges in its inventory, many of which were designed for H10 or H15 truck loads. Precast reinforced concrete flat slabs are the primary bridge type addressed. These components were chosen in consultation with SCDOT due to their prevalence in the bridge inventory and resolving associated performance issues will therefore have wide-ranging impact. The challenges associated with these components include a) original structural design loads that are lower than those used today, and b) ages approaching or exceeding expected lifespan in combination with deterioration. This report focuses on cost-effective, realistic, and innovative approaches to the challenges confronting South Carolina's bridge inventory. Several strengthening methods have been developed to increase the strength of posted bridges and to provide an additional target service life of 10 years.
