The Manual for Bridge Evaluation
|Publication Date:||1 January 2018|
The Manual has been divided into eight Sections, with each Section representing a distinct phase of an overall bridge inspection and evaluation program.
• Section 1-Purpose, scope, applicability, inspection and evaluation quality measures, and definition of general interest terms.
• Section 2-Provisions for proper documentation to be included in a bridge file. The bridge file associated with each bridge provides the foundation against which changes in physical condition can be compared.
• Section 3-Overview of bridge management systems and their key elements.
• Section 4-Types and frequency of field inspections, as well as specific inspection techniques and procedures.
• Section 5-Various inspection and evaluation testing methods. Conditions at a bridge site or the absence of information from original construction may warrant more elaborate material tests to determine properties for evaluation.
• Section 6-Nationally recognized specification for the load rating of bridges. Includes the Load and Resistance Factor method, the Load Factor method, and the Allowable Stress method.
• Section 7-Provisions for the evaluation of existing bridges for fatigue.
• Section 8-Field-performed load test procedures. Field load testing is a means of supplementing analytical procedures in determining the live-load capacity of a bridge and for improving the confidence in the assumptions.
The successful application of this Manual is directly related to the DOT organizational structure. Such a structure should be both effective and responsive so that the unique characteristics and special problems of individual bridges are considered in developing an appropriate inspection plan and load capacity determination.
