The increasing proportion of trucks with wide single-wheel axles makes asphalt pavements more vulnerable to creeping of the surface layers. Experiments on the circular test track of the Laboratoire Central des Ponts et Chaussees (LCPC) and laboratory tests focused on the effect of the type of binder [three asphalt-coated materials (a straight-run, conventional 50/70 grade bitumen; an SBS-polymer-modified bitumen; and the Shell Multigrade bitumen) and a very thin asphalt layer on a high-modulus coated material (hard bitumen 10/20 grade) were compared], the effect of the axle loading configuration (a wide single-wheel axle versus a traditional dual-wheel axle), and the capability of various laboratory tests (LCPC wheel tracking rutting test, static and dynamic creep tests) to rank the materials according to their resistance to rutting as observed on the test track. The observations made on the asphalt pavements and the results of the tests on the binders and the asphalt-coated materials are described. The higher aggressiveness of the wide single-wheel axles on the test track is discussed.
