FOURTH NATIONAL WORKSHOP ON BRIDGE RESEARCH IN PROGRESS:
 
RESEARCH ABSTRACT
 
Title:
Characterization of the Environment for Weathering Steel Design Considerations
Author(s) and Affiliation(s):
Christopher L. Farschon and J. Peter Ault Ocean City Research Corporation, Ocean City, NJ Robert A. Kogler, Turner-Fairbank Highway Research Center Federal Highway Administration, McLean, VA
Principal Investigator:
Christopher L. Farschon
Sponsor(s):
Federal Highway Administration
Research Start Date:
1992
Expected Completion Date:
1998
Research Objectives:
The objective of this project is to identify the components that contribute to the corrosivity of the atmospheric environment. The performance of weathering steel and various coating materials are being studied in representative environments across the continental U.S. Meteorological data will be gathered along with material performance data, which will be used to formulate design guidelines for steel highway structures based upon the characteristics of the various macro-environments.
Expected Products or Deliverables:
The research will yield a variety of new knowledge about the corrosion of weathering steels in various environments and will attempt to correlate environmental parameters with expected performance. Novel test techniques are being developed that could be used to ascertain the corrosion suitability of weathering steel for a given environment during the design phase of a structure. This will allow bridge engineers to base material selection (steel type and coatings type) on environmental data that is either readily available or easily gathered during the design and planning phases of bridge construction.
