Synthesis of Information Related to Highway Problems. Topic 36-01. Bridge Rating Practices and Policies for Overweight Vehicles

State permitting offices and industry have worked toward a goal of increased uniformity in permitting of overweight/oversize trucks within and between States. Relatively little attention has been directed toward the contribution of state bridge rating practices and procedures toward achieving this goal. Bridge rating practices vary between states. Choice of software tools, treatment of non-standard configurations (such as axle gauges and multiple-lane configurations), choice of specifications, interpretation of specifications and allowances for in-place dead loads are examples of those areas where variation in practice often exists. The extent of these differences and their impact on the goal of more uniform permitting is poorly understood. Identifying and documenting the different bridge rating practices used for overweight vehicle permits would be a very important step towards more uniform permitting. It is proposed that a synthesis be prepared to gather information on state bridge rating systems, practices and policies, as these relate to overweight and oversize vehicles. This will be done through literature review, survey, phone interviews, and case studies. Those contacted may include State DOT permitting and bridge rating offices, hauling companies, and construction and crane rental companies. This synthesis will allow permitting agencies and industry to efficiently and effectively direct their efforts toward increasing permit uniformity.
