Previous research investigating the dynamic road wear produced by heavy vehicles has not included the effect of road crossfall. This study shows that road crossfall, even at values as low as 1%, has a significant effect on the predicted dynamic road wear. A model of a rigid vehicle that includes rolling and pitching motion was developed for the analysis. The normalized 95th percentile aggregate fourth-power force is used as the road damage criteria. For the vehicle studied, a 24% increase in road damage is predicted for a crossfall value of 2% as compared to not modelling the crossfall, at a typical highway speed of 80 km/h and road roughness of 2 m/km. Road crossfall therefore plays a significant role in the dynamic road damage produced by heavy vehicles.
