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以惊人的速度增长。一些人估计，仅修桥一项的赤字就达80亿美元。该项目旨在开发一种创新的非破坏性技术，用于停车场和桥面等退化结构的状态评估，并确定使用修复材料修复时的分层增长率。此外，本项目旨在评估修复材料的粘结强度，开发一种自主的、原位的、非接触式的多用途钻机，该钻机将由不同类型的无损检测设备组成。该装置将收集实时数据，并同时标记（使用不同的颜色）的结构，被检查，这是在预定的限制。我们坚信，这个项目的发现将有助于RJC在未来的各种项目。具体而言，该项目将有助于量化结构的剩余使用寿命，并协助业主确定维修或结构改造的干预时间。因此，在巨大的税收美元节省和基础设施的安全改善.此外，还将促进对腐蚀蔓延的更深入了解，以及快速评估技术的完善，这不仅对公共安全而且对公共支出都至关重要。由于能够保守地预测腐蚀和分层的蔓延，因此可以在评估与延迟维修相关的风险和成本时确定时间表。快速评估还将降低执行评估的成本，从而使现有预算能够容纳更多的测试。

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.
