EFFECTS OF RAISING LOAD LIMITS ON PAVEMENTS AND BRIDGES IN INDIANA

The study evaluated possible changes in maintenance costs that might arise if heavier loads were to be permitted on Indiana highways. Pavement maintenance costs were determined for all highways on the Indiana state highway system including interstates, U.S. routes and state routes. This was done utilizing road life data on file in the ISHC offices. Traffic data from the loadometer stations, soil test data on file in the JHRP offices and physical data from the Research and Training Center were used to evaluate impacts of increased weights on Indiana pavements. Bridges were evaluated based largely on a comprehensive search of the literature. The report presents estimates of increased costs that might result if the weight limits were increased in Indiana. The conclusions apply to all highways on the state system and a discussion of possible impacts on the county systems is presented. (Author)
