Samenvatting
Twenty bridge maintenance and rehabilitation areas were identified and repair procedures were compiled for each area. Initial cost and life for each procedure was determine by expert opinion expressed during a group encounter session, for which guidelines and procedures are presented. An engineering economic evaluation of the alternative procedures for each of the 20 bridge maintenance and rehabilitation areas was performed considering the time value of money, sensitivity of least cost parameters, and economic intangibles. An economic decision tree presents the least cost solution to the identified bridge maintenance and rehabilitation areas for various field conditions.
