The introduction of element inspection condition methods in the early 1990s represented a significant advancement in bridge insp

40、ection practice and has been adopted by the vast majority of the state transportation departments in the United States. Bridge owners nationwide have recognized the benefits of detailed condition assessments through the use of the raw inspection information, expanded performance measures, and bridge

41、 management system deterioration forecasting and evaluation. As the use of element-level inspection techniques has proliferated, the need for updates and enhancements to the standard element specification has been identified. This manual incorporates improvements through changes in the measurement u

42、nits of decks and slabs, the development of a wearing surface element, the standardization of the number of element states, and the development of protective coating elements for concrete and steel, as well as deck protection systems. Elements constructed of innovative materials are also identified.

43、 The goal of this manual is to completely capture the condition of bridges in a simple, effective way that can be standardized across the nation while providing the flexibility to be adapted to both large- and small-agency settings. This manual is not intended to supplant proper bridge and element i

45、LOSOPHY: MULTIPATH AND DEFECT CONCEPTS The Manual for Bridge Element Inspection (this manual) builds on the element-level condition assessment methods developed in the AASHTO Guide for Commonly Recognized Structural Elements. Improvements have been made to fully capture the condition of the elements

46、 by reconfiguring the element language to utilize multiple distress paths within the defined condition states. The multipath distress language provides the means to fully incorporate all possible defects within the overall condition assessment of the element. The overall condition of an element can

47、be utilized in this aggregate form, or broken down into specific defects present as desired by the agency for Bridge Management System (BMS) use. This manual provides a comprehensive set of bridge elements that is designed to be flexible in nature to satisfy the needs of all agencies. The complete s

48、et of elements captures the components necessary for an agency to manage all aspects of the bridge inventory utilizing the full capability of a BMS. The element set presented within includes two element types identified as National Bridge Elements (NBEs) or Bridge Management Elements (BMEs). The com

49、bination of these two element types comprise the full AASHTO element set. All of the elements, whether they are NBEs or BMEs, have the same general condition assessment characteristics: 1. Standard number of condition states is four. 2. The standard condition states are good, fair, poor, and severe general descriptions. 3. Units of measure are length in feet, area in square feet, and each for enumerated elements. 1.2NATIONAL BRIDGE ELEME
