*NEW*  LRFD Bridge Design Specifications, 9th Edition

The AASHTO LRFD Bridge Design Specifications are intended for use in the design, evaluation, and rehabilitation of bridges. The specifications employ the Load and Resistance Factor Design (LRFD) methodology, using factors developed from current statistical knowledge of loads and structural performance. This new 9th edition includes revisions to almost all sections of the specifications.

Visit our Technical Service Program TSP2

The American Association of State Highway Transportation Officials (AASHTO) is dedicated to the preservation and maintenance of highway assets. In May 2006, the National Center for Pavement Preservation (NCPP) was contracted to develop and administer its new Transportation System Preservation Technical Services Program (TSP∙2). The program was initiated as an efficient means to disseminate information to AASHTO member agencies for preserving their highway infrastructure, including both pavements and bridges. Its principal mission will be to serve as a clearinghouse with comprehensive and up-to-date information on efficient and effective preservation measures that enhance highway performance and extend useful life.
