    Abstract: From the perspective of sprung vehicle dynamics, current highway design criteria are somewhat inadequate for fulfilling broad requirements of automated highway systems and automatic control vehicles. Therefore, in this study, we present a split layout of pavement friction, designed to counterbalance an insufficient superelevation and overcome unpredictable rolling instability. The proposed layout provides different friction pavements between a lane's left and right sides in a curve stretcher along a highway. Such a layout causes vehicles to be more stable in dynamic. In addition, no deficiency arises in setting superelevations, of which, the inclined cross-sections potentially cause side slipping under poor weather conditions. The optimal friction difference values are also illustrated in terms of the radius with respect to AASHTO's criteria. Finally, some implementation issues are also addressed.
