摘要：	The new American Association of State Highway and Transportation Officials (AASHTO) Manual for Condition Evaluation and Load and Resistance Factor Rating of Bridges being developed under National Cooperative Highway Research Program (NCHRP) Project 12-46 will be consistent with the AASHTO Load and Resistance Factor Design (LRFD) Bridge Design Specifications in using a reliability based limit states philosophy. The primary goal of this project is to produce a practical evaluation manual that is easy to understand and use, which will receive broad support for adoption and distribution by the AASHTO Subcommittee on Bridges and Structures. The reliability aspects will remain invisible to the evaluation engineer through the use of calibrated load and resistance factors, as was done in the LRFD Specifications. A pre-final Draft Manual was submitted for review and testing in March 1999 and the final Draft Manual is scheduled for completion by the end of 1999. The new Manual provides procedures and calibrated load and resistance factors for load rating and for overweight permit review.
