TRB will conduct a webinar on Tuesday, October 10, 2017 from 2:30 PM to 4:00 PM ET that features research from the National Cooperative Highway Research Program (NCHRP)’s Report 848: Inspection Guidelines for Bridge Post-Tensioning and Stay Cable Systems Using NDE Methods.

This webinar will evaluate inspection guidelines of non-destructive evaluation (NDE) methods for assessing the condition of in-service post-tensioning and stay cable systems. The presenters will provide information about how multiple NDE technologies are evaluated, and how bridge owners can select the most appropriate method for evaluating their systems.

Some registrants will need to pay $95 to attend this webinar.  Sign into to view registration information.
