Delamination growth rate evaluation in repairs using non-destructive techniques

在加拿大，修复现有基础设施的赤字正在以惊人的速度增长。一些人估计， 仅修复桥梁就有80亿美元的赤字。该项目将致力于开发创新的无损检测技术 劣化结构的状态评估和确定分层增长率的技术 当使用修复材料进行修复时。此外，该项目旨在开发一种多用途钻井平台，可以 用于存放不同类型的无损检测设备，收集数据，同时标记截面的 结构不在预定限制之外。这个项目的发现有望帮助RJC 各种未来的项目。该项目的研究结果将有助于量化结构的剩余使用寿命和 协助业主确定维修或结构改造的干预时间。从而产生税收美元 节约和改善基础设施安全。对两者的发展都有了更深入的了解 腐蚀以及快速评估技术的完善不仅对公共安全至关重要，而且对 还有公共支出。有能力保守地预测腐蚀和分层的扩散， 在评估与延迟维修相关的风险和成本时，可以确定时间表。快速 评估还将降低执行评估的成本，从而使现有预算能够满足 更多的测试。此外，通过更准确的测试，混凝土去除量等不确定因素可以 经过改进，为项目预算提供了更多确定性。

In Canada, the deficit to fix existing infrastructure is increasing at an alarming rate. Some estimates put the deficit to fix bridges alone at $8 billion. This project will aim at developing innovative Non-destructive techniques for condition assessment of deteriorating structures and to determine the delamination growth rate when repaired using a repair material. Further, this project aims at developing a multipurpose rig that can be used to house different types of NDT equipment, gather the data and at the same time mark sections of the structure that are outside a predetermined limit. The findings of this project are expected to help RJC on various future projects. Findings of this project will help quantify the remaining service life of structures and assist owners in determining the intervention time for repair or structural retrofit. Thus resulting in tax dollar savings and infrastructure safety improvement. Development of both a greater understanding of the spread of corrosion, as well as the refinement of rapid assessment techniques is essential for not only public safety but also public spending. With the ability to conservatively predict the spread of corrosion and delamination, timelines can be determined when assessing the risk and costs associated with delaying repair. Rapid assessment will also lower the costs to perform the assessments, allowing for existing budgets to accommodate more testing. In addition, with more accurate testing, uncertainties such as concrete removal quantities can be refined, providing more certainty in project budgets.
