Synthesis of Information Related to Highway Practices. Topic 52-01. State of Practice on Infrastructure Inspections for the Digital Age

Highway infrastructure inspection is critical in any transportation system because it ensures conformance with plans, specifications, and material requirements over the lifecycle of the asset. Historically, state departments of transportation (DOTs) have employed on-site workforces to execute infrastructure inspection using traditional inspection methods. With the latest technological advancements, the inspection landscape has been rapidly changing through incorporation of technologies such as Unmanned Aircraft Systems (UAS), embedded and remote sensors, intelligent machines, mobile devices, and new software applications. These technologies can potentially satisfy the need for cost-effective and efficient inspection and monitoring of highway infrastructure (e.g. roadways, bridges, drainage systems, signage). The objective of this synthesis is to document the various technologies used by DOTs to inspect highway infrastructure during construction and maintenance of assets. Information to be gathered includes (but is not limited to): (1)The technologies used for inspection of new and existing highway infrastructure assets (e.g., geospatial technologies, mobile software applications, nondestructive evaluation, remote sensing and monitoring); (2) The different methods used to assess the viability, efficiencies, and return on investment (ROI) of inspection technologies; (3)  How information from these assessments is being used (e.g., for construction project management, to allocate resources, to determine condition of the asset). Information will be collected through literature, a survey of DOTs, and follow-up interviews with selected agencies for the development of case examples. Information gaps and suggestions for research to address those gaps will be identified.
