162 S E C T I O N 6 The objective of this research was to develop superelevation criteria for sharp horizontal curves on steep grades. For this research, a sharp horizontal curve is defined as a minimumradius curve as determined based upon the design speed, maximum rate of superelevation, and maximum side friction factor.
