N2 - Accurate estimates of characteristic traffic load effects are greatly beneficial in prioritizing bridges for repair and replacement. The extreme loading events likely to cause characteristic load effects are dominated by very heavy permit trucks. As these trucks are significantly heavier and are subject to stricter controls than standard trucks, they may be treated separately from the general truck population. This paper examines truck loading at 3 Weigh-in-Motion (WIM) sites in the United States and develops filtering rules to identify permit trucks based on the available axle spacing information. Once all trucks have been classified, permit and standard trucks are examined separately to get a better understanding of their importance for bridge loading.AMonte Carlo simulation model is developedwhich allows permit trucks to be simulated independently of the standard truck population. The truck simulation model is used to investigate the changes in characteristic load effects resulting from changes in permit-issuing policy.
