Abstract: Superelevation design is an important part in highway route design,and reasonable superelevation design is a premise to guarantee driving stability in curve sections. In consideration of drainage problems and comfortableness of driving,reverse superelevation is not appeared in superelevation design. Mainly aimed at the reverse superelevation problems caused by the improper radius of circular curve in highway superelevation design,this paper obtains the radius scope which appears sreverse superelevation corresponding to different design speed by the analysis of the relationship between reverse superelevation and radius,and puts forward the methods for avoiding reverse superelevation in route design to provide reference for highway route design.
