In the last years three experiments have been carried out withLCPC accelerated loading facility to investigate the rutting resistanceof different wearing courses. As far as asphalt concretes wereconcerned, attention was paid to the influence of the nature ofthe binder, keeping the other parameters constant. The referencemix was selected with a given proportion of rounded sand and a50/70 pen grade pure bitumen. The performance of this materialwas compared to mixes with polymer modified binders, special bitumenand bitumen with additives. These materials were used in a 8 cmthick surface layer. A comparison was also made with a high modulusasphalt concrete as a bounding layer covered by a very thin bituminousconcrete. Depending on the experiments the loading axles weresingle large wheels or common dual wheels. A heating system wastested to increase the temperature in the pavement upper layers.Data were obtained on the influence of the material type, loadings,and temperature on rutting.
