Dept. of TransportationUS Transportation CollectionThis report develops a methodology for estimating the effects of different categories of overweighttrucks on NYSDOT pavements and bridges. A data mining algorithm is used to categorize truckdata collected at several Weigh-In-Motion stations around the state of New York based on thetrucks\ue2\u20ac\u2122 adherence to the state\ue2\u20ac\u2122s legal weight limits. The data indicate that about 11% of the truckstraveling on New York highways may be carrying divisible load permits, 1% may be carryingspecial hauling permits, while about 6% may be illegally overweightThe analysis shows that these overweight trucks are increasing the risk to failure of bridges bycausing stresses above those specified in design specifications and by reducing bridge service(fatigue) lives through repetitive overloading. A monetization of the safety margin utilization dueto the combined overstress and cyclic fatigue shows that trucks carrying divisible load permitsmay be responsible for $50M per year in NYS bridge infrastructure cost, trucks with specialhauling permits may be responsible for $2M/yr in additional cost while illegally overweight trucksmay be responsible for $43M per year for a total of $95M/yr.The cost allocation study performed on the NYS pavement network shows that the cost toNYS pavements due to overweight trucks is about $145M/yr divided into $78M/yr for divisible loadpermits, $7M/yr for special hauling permits and $60M/yr for illegally overweight trucks
