FOURTH NATIONAL WORKSHOP ON BRIDGE RESEARCH IN PROGRESS:
 
RESEARCH ABSTRACT
 
Title:
Investigation of Two Bridge Alternatives for Low Volume Roads
Author(s) and Affiliation(s):
Terry J. Wipf, F. Wayne Klaiber, Brent M. Phares and Jeff W. Reid Bridge Engineering Center, Department of Civil and Construction Engineering Iowa State University, Ames, IA
Principal Investigator:
Terry J. Wipf and F. Wayne Klaiber
Sponsor(s):
Highway Research Board and the Highway Division of the Iowa Department of Transportation
Research Start Date:
June 12, 1995
Expected Completion Date:
December 31, 1996
Research Objectives:
Iowa county engineers are responsible for over 20,000 bridges on the secondary road system. As their budgets are limited, many county engineers design and construct short span bridges with their own labor forces. With the assistance of several county engineers, two bridge alternatives have been developed for use on low volume roads. The primary objective of this investigation is to test the alternatives in the laboratory to obtain strength and structural behavior data.
Expected Products or Deliverables:
Assuming successful completion of this investigation, it is envisioned that demonstration projects utilizing the two concepts will be undertaken. Construction of the demonstration bridges would be documented, videotaped, etc., for use in training county crews for such bridge construction.
