Evaluating Repair Processes for Concrete Bridge Decks and Barriers Reinforced with Glass Fibre Reinforced Polymer Bars**

自20世纪80年代末以来，玻璃纤维增强聚合物（GFRP）钢筋在钢筋混凝土桥梁中被用来代替钢筋。GFRP优于钢材的主要优点是它不生锈；这将降低长期成本。因此，GFRP在桥面和护栏中越来越受欢迎。**然而，与钢加固桥梁相比，gfrp加固车辆碰撞损坏的桥面和障碍物的修复方法并不完善。这限制了GFRP在加拿大某些地区的使用。**以前对玻璃钢加固桥面和屏障的试验集中在未损坏的结构上。很少检测损坏的玻璃钢系统；现有的研究涵盖了一组有限的修复选项。本工程将试验四种gfrp加固桥面和桥障的修复方法。这些试验的结果将用于为桥梁工程师创建修复gfrp加固桥梁的新设计文件。在加拿大桥面中增加玻璃钢加固的使用将使桥面更持久，维修/维护成本更低。这将最大限度地节省纳税人在基础设施上的开支，并最大限度地减少由于建设和维护造成的交通延误。****

Glass Fibre Reinforced Polymer (GFRP) bars have been used instead of steel bars in reinforced concrete bridges since the late 1980's. The main advantage of GFRP over steel is that it does not rust; this leads to lower long-term costs. For this reason, GFRP is becoming more popular for bridge decks and barriers.**However, repair methods for GFRP-reinforced bridge decks and barriers damaged by vehicle collisions are not that well developed compared to those for steel-reinforced bridges. This limits the use of GFRP in some areas of Canada. **Previous tests on GFRP-reinforced bridge decks and barriers focused on undamaged structures. Testing damaged GFRP systems is rare; available research covers a limited set of repair options. Four repair methods for GFRP-reinforced bridge decks and barriers will be tested in this project. The results of these tests will be used to create new design documents for bridge engineers for repairing GFRP-reinforced bridges. Increasing the use of GFRP reinforcement in Canadian bridge decks will lead to longer-lasting decks with lower repair/maintenance costs. This will maximize taxpayer savings on infrastructure and minimize traffic delays due to construction and maintenance.****
