A Study on the Requirements for Minimum Longitudinal Slope of the Vertical Curve on the Freeway

Abstract:

The varying laws of the longitudinal grade at the partial any point on the vertical curve in the course of the freeway’s profile design were discussed via the analytical formulas calculation, and the minimum longitudinal gradient and the length of roads which cannot meet the current requirements were found out, then application effect of vertical curves with the large radius was explored. On this condition, some countermeasures and suggestions were provided for the reasonable design of the vertical curves.
