COST-EFFECTIVE METHODOLOGY FOR THE REHABILITATION AND REPLACEMENT OF BRIDGES

A cost-effective methodology was developed using mathematical models for rehabilitation and replacement which are based on generalized cash flow diagrams. The models present a least cost solution to bridge work based on the service life of the bridge and considering the time value of money. The effect of inflation can also be taken into account. A microcomputer program for the Apple IIe is given to solve the mathematical models. Example solutions are also presented. A related report, FHWA/PA 84-003, A Collection of Attempted Maintenance Force Remedial Bridge Work, describes and illustrates 36 repair standards and methods in 21 selected maintenance rehabilitation systems.
