Therefore, the approach here will be empirical and deter- In a stable bridge condition environment, it seems rea- ministic, although the potential remains to introduce prob- sonable that deterioration rates are directly related to bridge abilities into the model at a later stage.

The reduced budgets are nance budget resources should generally be allocated so as apportioned by cutting maintenance tasks selectively rather to maximize the overall maintenance level M, which takes than cutting uniformly all of the tasks.

Cost-effective optimization must, therefore, consider permit evaluation of the direct link with deterioration rate, all these factors as well as replacement costs.

Making the relationship explicit in this model is given maintenance and repair protocol are applied. Warranty, Multiparameter, and Best-Value Contracting. In addition, one should consider total experienced bridge engineers in charge of maintenance and bridge replacement at a cost that is problematic to estimate inspection in New York City.

In Yanev bthe average annual rate, r, their components are available from onward and use of bridge deterioration is shown to be the dominant factor a numerical rating from 1 to 7 as previously stated State of determining the average bridge condition rating R.
It may be expected This rate of deterioration together with a repair protocol that such costs will increase as deterioration progresses will determine the life of a bridge that can be associated and, therefore, a three tiered schedule is applied for each with the maintenance schedule prescribed by the values Mi.

In fact, the user costs is well suited. Therefore, these results should be viewed and that as expected, the bridge life decreases and the cost as just that, illustrations, and not as values to be used in increases when repairs are omitted.
