This paper presents results obtained so far from a Swedish full-scale test, comprising in total 19 different rigid, semi-rigid and flexible test stretches. The purpose is to compare rutting performance of the different pavement categories and types using extensive laboratory tests and field measurements after seven years of trafficking. The rigid pavements withstand rutting better than the two other pavement categories due to comparably small abrasion and negligible permanent deformation. The semi-rigid pavements show less rutting than the flexible pavements, which primarily is the result of the negligible permanent deformation in the cement bound layers. Even though the rigid pavements show very small rutting, it is probably not the main distress type and the primary trigger for maintenance activities for this pavement type. In the case of semi-flexible and flexible pavements, both laboratory tests and field measurements indicate that significantly improved rutting performance can be obtained using appropriate asphalt mixtures manufactured using wear-resistant aggregates and stiff binder.
