Phase II: 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，仅修复桥梁的赤字就高达80亿美元。该项目旨在开发一种创新的非破坏性技术，用于评估停车场和桥面等劣化结构的状况，并确定使用修复材料修复时的分层增长率。此外，该项目旨在评估修复材料的粘结强度，开发一种由不同类型的无损检测设备组成的自主、就地和非接触的多用途钻机。钻井平台将收集实时数据，同时(使用不同的颜色)在被检查的结构上进行标记，这些标记超出了预定的限制。我们坚信，这个项目的发现将有助于RJC在未来的各种项目上。具体地说，该项目将有助于量化建筑物的剩余使用寿命，并帮助业主确定维修或结构翻新的干预时间。因此，节省了大量的税收，改善了基础设施的安全。此外，这将使人们更好地了解腐蚀的蔓延，并改进快速评估技术，这不仅对公共安全而且对公共支出都是至关重要的。由于能够保守地预测腐蚀和分层的扩散，在评估与延迟修复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，使现有预算能够容纳更多测试。

In Canada, the deficit to fix existing infrastructure is increasing at an alarming rate. Some estimates put thedeficit to fix bridges alone at $8 billion. This project will aim at developing an innovative Non-destructivetechniques for condition assessment of deteriorating structures such as parking garages and bridge decks and todetermine the delamination growth rate when repaired using a repair material. Further, this project aims atevaluating the bond strength of the repaired material, develop an autonomous, in-situ, and non-contactmultipurpose rig that will consist of different types of NDT equipment. The rig will gather real-time data andsimultaneously marks (using different colors) on the structure, being examined, which are outside thepredetermined limit. It is strongly believed that the findings of this project will help RJC on various futureprojects. Specifically, this project will help quantify the remaining service life of structures and assist owners indetermining the intervention time for repair or structural retrofit. Thus, resulting in huge tax dollar savings andinfrastructure safety improvement. Also, lead to the development of both a greater understanding of the spreadof corrosion, as well as the refinement of rapid assessment techniques, which is essential for not only publicsafety but also public spending. With the ability to conservatively predict the spread of corrosion anddelamination, 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 toaccommodate more testing.
