In recent discussions of the amount of superelevation that should be given highways at curves the writer has failed to note any mention made of the resistance of the pavement surface to slipping or skidding and how such resistance should be considered in determining what is the proper superelevation. One effect of the failure to consider this phase of the problem has resulted in unnecessary refinements in the practical application of the mathematical formulas involved.
