Superelevation design has many limitations. Therefore, in this study, we describe a split layout of pavement friction, designed to counterbalance an insufficiency of superelevation. The layout is to provide different friction pavements between the left and the right sides of a lane in curves. Such a layout would cause vehicles to be more stable, in addition to providing passengers with more comfort. There is no deficiency of placing superelevations, of which the inclined cross-sections possibly cause side slipping in bad weather conditions. Also, the ideal values of friction difference for high design speeds versus various radii are illustrated. How to implement a split friction pavement is also introduced accompanied by an analysis of the selection of materials or aggregates. Finally, a special consideration regarding safety for constructing such a pavement is mentioned. |
