ASNT FOCUS ISSUE EDITOR SREENIVAS.ALAMPALLI@ STANTEC.COM I consider the next decade to be a golden era for development and use of NDE technologies in highway infrastructure, including bridges. HIGHWAY INFRASTRUCTURE INSPECTION It is a pleasure to share this focus issue on highway infrastructure inspection and evaluation with all of you. Highway bridges have been inspected using visual testing (VT) methods for more than 100 years, but the extent, frequency, personnel qualifications, and quality of these inspections have varied significantly depending on the owners. It should be noted that in bridge management terminology, the term “inspection” refers to (field) visual inspection of structures, which is equivalent to visual “testing” as used by ASNT. The word “testing” mostly refers to the use of NDT methods such as magnetic particle testing (MT), liquid penetrant testing (PT), and ultrasonic testing (UT), as well as to static and dynamic load testing. The roots of current structured inspections mandated by Federal Highway Administration (FHWA) can be traced back to the collapse of the Ohio River Bridge (known as the “Silver Bridge”) in 1967, which killed 46 people. This led to the establishment of the National Bridge Inspection Standards (NBIS) that defined structured inspection of publicly owned bridges nationwide, including inspection frequen- cies and qualifications. NBIS have been updated since then based on lessons learned from various failures—for example, the collapse of Schoharie Creek Bridge in New York State in 1988 led to under- water inspections at regular intervals. Until recently, the primary focus of these guidelines has been public safety by avoiding partial or full collapse of structures. Therefore, VT is predominantly used, with other methods used for local characterization of defects as further investiga- tion based on inspectors’ recommendations. The role of infrastructure in modern societies has changed from being a means to move people and goods from one place to another. Mobility, reliability, economic competitiveness, and security, in addition to safety, are expected by the public and consequently are important performance measures for owners in a resource-constrained envi- ronment. This shift in public expectations renewed emphasis on preservation and mobility-focused asset management, meaning finding deterioration and inspection methods that require low service interruptions becomes very important. Therefore, changes to NBIS in recent years have been focused on collecting data for effective and proactive asset management. This issue focuses on recent changes and developments in that direction. At the same time, ensuring quality during construction is also important, and there is renewed emphasis on QA/QC of construction using nondestructive testing methods. This issue has five papers. The first by Alampalli, Jalinoos, and Ailaney discusses recent changes in NBIS in the direction of asset management and preservation focus. They also discuss recent changes in technologies associated with aboveground inspections and corrosion mitigation as a prelude to rest of the papers. Most failures are attributed to bridge scour underwater inspections play J A N U A R Y 2 0 2 3 • M AT E R I A L S E V A L U AT I O N 7 2301 ME Jan New.indd 7 12/20/22 8:14 AM
