Intended Audience
This course is intended primarily for civil, construction, and structural engineers, and would be of particular interest to consulting engineers or to engineers serving in government organizations concerned with the maintenance of bridges.
Benefit to Attendees
An attendee of this course will be familiar with and able to apply procedures for maintaining bridge superstructures.
Course Introduction
Maintenance is required on the total structure. Often the superstructure is the most difficult part of the structure to access and problems tend to be overlooked or ignored for this reason. Areas on the superstructure where maintenance is particularly important are the bearings, under joints, under drains, anon the fascia.
Course Content
This course is based on Chapter XI (Superstructure Maintenance Procedures) of the Federal Highway Administration Bridge Maintenance Training Reference Manual, Publication No. FHWA- NHI-03-045, March, 2003.
