• Abstract:
  A review of some texture-measuring techniques was made and a limited number of microtexture measurements of pavement surfaces was obtained with the Clevite BL-185 Surfindicator. This instrument is generally used to measure uniform textures on surfaces such as those found on finished metallic parts. The results of the investigation revealed that the Surfindicator has some undesirable features for measuring microtextures of pavement surfaces. Based on a limited number of tests, a trend was found between skid numbers at 40 mph and microtexture values; however, the correlation coefficient between the parameters was not very high. Significant differences between the microtextures of some pavement surfaces were determined by the device. Recommendations are given to continue microtexture measurements with the Surfindicator on a limited basis and to develop another instrument to obtain macrotextures as well as microtextures.
