Automatic generation of truck configurations for bridge load ratings in the state of North Carolina

This paper describes a methodology to automatically generate truck configurations based on state statutes that regulate axle weights of legal vehicles. Axle weights of legal vehicles are generally used to load rate bridge structures. The particular methodology described in this paper is based on the North Carolina General Statute. The paper also describes the functionality of the computer program that generates truck configurations based on the statute. The computer program constituted a deliverable to the North Carolina Department of Transportation (NCDOT) under grant FHWA/NC/2017–07.
