Abstract:
To achieve a sustainable level of development in the next century, it is apparent that funding for bridge repair and maintenance will have to be increased substantially. Recognizing the funding constraints that exist due to the other deficient components of the infrastructure, it is apparent that the effectiveness or return on the available funding needs to be maximized. This can only be accomplished by increasing the minimum service life, or useful life, to 100 or 120 years and selecting structures on the basis of reasonable life-cycle cost analyses. For major bridges in urban environments, the minimum service life should probably not be less than 150 years.
