TRB Special Report 227 - New Trucks for Greater Productivity and Less Road Wear: An Evaluation of the Turner Proposal evaluates the approach to regulation of the size and weight of trucks using U.S. roads known as the Turner Proposal. This approach had its origin in a proposal put forth in a 1984 address to AASHTO by former Federal Highway Administrator Francis C. Turner. The approach evaluated by the committee differs in an important respect from Turner's original concept: in the committee's approach, use of the new trucks would be voluntary; that is, truck operators would be offered the choice of continuing with existing equipment and weight rules or adopting the new trucks with the new weight regulations. The committee designed a package of changes in size and weight limits, safety restrictions, and procedures regarding bridge deficiencies, routing, and enforcement that would be a practical regulatory scheme for implementing the Turner concept. The committee recommends that every state, with careful assessment of the risks and uncertainties, consider this proposal as a supplement to current size and weight regulations. If Turner trucks were adopted in all states according to the recommended rules, they would reduce the cost of shipping freight and would not degrade safety. The total cost of maintaining the road system would be reduced, although pavement wear savings would be partially offset by higher bridge costs. The committee that carried out this study identified two truck configurations outside the weight and length limits established by federal law that would offer greater productivity without increasing infrastructure or safety costs. These vehicles formed the basis for the configurations recommended in a later (2002) TRB report, Special Report 267: Regulation of Weights, lengths, and Widths of Commercial Motor Vehicles.

Book Description
TRB's National Cooperative Highway Research Program (NCHRP) Report 683: Protocols for Collecting and Using Traffic Data in Bridge Design explores a set of protocols and methodologies for using available recent truck traffic data to develop and calibrate vehicular loads for superstructure design, fatigue design, deck design, and design for overload permits. The protocols are geared to address the collection, processing, and use of national weigh-in-motion (WIM) data. The report also gives practical examples of implementing these protocols with recent national WIM data drawn from states/sites around the country with different traffic exposures, load spectra, and truck configurations. The material in this report will be of immediate interest to bridge engineers. This report replaces NCHRP Web-Only Document 135: Protocols for Collecting and Using Traffic Data in Bridge Design. Appendices A through F for NCHRP Report 683 are available only online.

Book Description
A How-To Guide for Bridge Engineers and Designers Highway Bridge Superstructure Engineering: LRFD Approaches to Design and Analysis provides a detailed discussion of traditional structural design perspectives, and serves as a state-of-the-art resource on the latest design and analysis of highway bridge superstructures. This book is applicable to highway bridges of all construction and material types, and is based on the load and resistance factor design (LRFD) philosophy. It discusses the theory of probability (with an explanation leading to the calibration process and reliability), and includes fully solved design examples of steel, reinforced and prestressed concrete bridge superstructures. It also contains step-by-step calculations for determining the distribution factors for several different types of bridge superstructures (which form the basis of load and resistance design specifications) and can be found in the AASHTO LRFD Bridge Design Specifications. Fully Realize the Basis and Significance of LRFD Specifications Divided into six chapters, this instructive text: Introduces bridge engineering as a discipline of structural design Describes numerous types of highway bridge superstructures systems Presents a detailed discussion of various types of loads that act on bridge superstructures and substructures Discusses the methods of analyses of highway bridge superstructures Includes a detailed discussion of reinforced and prestressed concrete bridges, and slab-steel girder bridges Highway Bridge Superstructure Engineering: LRFD Approaches to Design and Analysis can be used for teaching highway bridge design courses to undergraduate- and graduate-level classes, and as an excellent resource for practicing engineers.
