Timber Bridge Webinar Series – Field Performance of Timber Highway Bridges: A National Study
September 30, 2014 – 10:00 am - 11:00 am
Welcome to Timber Bridge Tuesdays Sept 9th – Oct 14th! We will be covering various topics related to timber bridge technology in a series of 6 weekly Webinars.
Join at 8 am Pacific, 9 am Mountain, 10 am Central, 11 am Eastern
This webinar will provide an overview of the recently completed National Timber Bridge Inspection Study jointly administered by the Forest Products Laboratory (FPL) and Federal Highway Administration (FHWA). The overall aim of this first-of-its-kind effort was to estimate the service life of timber highway bridges and their comparative durability within the various climate zones within the U.S. A description of timber bridge superstructure types and locations as well as the field inspection protocol employed by all inspectors is also provided. Inspection results will be presented for the 132 bridges included, by climate zone and by superstructure type, and solutions to common deterioration issues will be highlighted.
