    Abstract

    Accurate measurement of highway skid resistance has required the application of appropriate reference standards for the calibration of locked wheel skid trailers [ASTM Test for Skid Resistance of Paved Surfaces Using a Full-Scale Tire (E 274-70)] used as test equipment. This investigation was concerned with the development of criteria needed for the design of primary standard reference pavement surfaces.

    A parametric study of the effect of pavement texture on skid number, comprising laboratory experiments with model pavement surfaces, offers new insight into a solution of the problem.
