Passings of heavy vehicles is a common cause of distress on thin and narrow cycle paths. The lack of lateral support at the edge and increased moisture content in the unbound granular materials are two important factors that affect deterioration. Three full-scale instrumented cycle path structures with different structural designs were constructed in a concrete pit at the Swedish National Road and Transport Research Institute (VTI) test facility. Response measurements were conducted with a falling weight deflectometer (FWD), a light weight deflectometer (LWD), and light, standard and heavy maintenance vehicles at three different groundwater table scenarios. The results confirm reduced load-bearing capacity close to the cycle path edge, and at an increased groundwater table. In general, larger transverse tensile strains can also be expected in the asphalt layer close to the edge.
