Automated Crack Documentation Using Digital Images - Scoping Study

The Texas Department of Transportation (TxDOT) inventory contains approximately 53,000 bridges. About 60% of these bridges have reinforced/prestressed concrete structures. Inventory maintenance requires regular inspection which includes detecting, documenting, and tracking of cracks. Current TxDOT bridge inspection is manual and based on human visual inspection. This introduces several issues including: inspection accuracy, reliability, safety, duration, and cost. Automating parts of the process, and assisting inspectors with other parts, might be desirable. Yet several considerations including feasibility, cost, and usability of the system have to be considered. For this end, this scoping study will explore the feasibility of developing a simple, usable, economical, and safe crack documentation, detection, and inspection system (CDD-IS).
