Evaluation of Corrosion Prevention and Mitigation Approaches Used On Texas Bridges
| 项目名称： | Evaluation of Corrosion Prevention and Mitigation Approaches Used On Texas Bridges |
| 摘要： | Corrosion of steel has been causing millions of dollars of loss in infrastructure to the state of Texas. The use of corrosion-resistant reinforcement in concrete structures and painting of steel elements have been the most common mitigation strategies. In addition, the use of weathering steel, metalizing on steel and concrete elements, and cathodic protection (sacrificial anode) have also been applied on TxDOT bridges. The performances of different approaches vary with different bridges in different geographic areas; i.e., cold, arid, and humid districts. It is imperative for the TxDOT to have a decision tool to conduct effective corrosion prevention for new construction and corrosion mitigation for effective maintenance.The project objectives are to (1) conduct a synthesis of worldwide field investigations of the performance of corrosion mitigation, (2) perform field evaluations statewide to investigate the effectiveness of corrosion mitigation instrumented in the past, and to (3) perform lab tests, as necessary, to verify findings and to obtain a better understanding of corrosion mitigation approaches. |
