Structural Performance of Longitudinally Post-Tensioned Precast Deck Panel Bridges
… report focuses on the short-term and long-term testing of this bridge. The short-term testing involved performing a live load test in which two trucks of known weight and dimensions were positioned on the bridge in order to maximize the negative moment at the joints over the piers and document …

VHPC Material Characterization and Recommendations for the Buffalo Branch Bridge Rehabilitation
… Concrete (UHPC) and extensive material tests were performed. The results of the material testing of VHPC and grout revealed that VHPC had higher compressive and tensile strengths, a higher modulus of elasticity, gained strength faster, bonded better to precast concrete, was more durable …

Load Testing Deteriorated Spans of the Hampton Roads Bridge-Tunnel for Load Rating Recommendations
… Virginia coast has taken its toll on the main load carrying girders. Concrete spalling has exposed prestressing strands within the girders allowing corrosion to spread. Some of the more damaged girders have prestressing strands that have completely severed due to the extensive corrosion. The …
