EFFECTS OF TRANSVERSE DISTRIBUTION OF HEAVY VEHICLES ON THICKNESS DESIGN OF FULL-DEPTH ASPHALT PAVEMENTS

One of the most important parameters involved in the design of road pavements is the expected traffic load. This factor has a direct bearing on the thickness requirements of the pavement. For practical purposes, only the loading from heavy-goods vehicles should be considered as, in comparison, the loading from private cars has a negligible effect. When deciding on the layer thicknesses of a road pavement, it is essential to know whether the traffic will be concentrated in one wheel path, or distributed across the width of the traffic lane. When commercial vehicles travelling along a roadway use wheel paths that are transversely distributed across the traffic lane (lateral shifts of the wheel path), the pavement is less severely loaded at representative points in the cross section than when the vehicles all follow the same wheel path (uniform wheel path). The Road and Hydraulic Engineering Division of the Dutch Department of Public Works has carried out further research into the phenomenon of transversely distributed heavy-goods vehicles and the ffect of lateral shifts of the wheel path on the design of flexible pavements. The study was particularly concerned with investigating how this phenomenon relates to roads with a full-depth asphalt pavement with specific material properties.
