Recent update of AASHTO LRFD Bridge Construction Specifications
In the United States of America many welded components on existing bridges are prone to fatigue failure. The US Federal Highway Administration (FHWA) estimates that $76 billion is necessary to repair deficient bridges throughout the country.
Research conducted by Purdue University in 2018 has shown that Ultrasonic impact treatment is a highly effective technique for increasing the fatigue life of welded girders.
The study was recently extended to prove that equipment manufactured by Empowering Technologies is accepted as a reliable option for UIT application. The “AASHTO LRFD Bridge Construction Specifications” was modified as such in the 2020 Interim Revisions released in September of 2019.
