    Abstract

    As part of a major study to develop methods for predicting tire friction performance on all types of pavements, macrotexture measurements were taken on a variety of concrete and asphalt surfaces using several different volumetric and drainage techniques. Expressions are developed which relate data obtained with each technique. Factors influencing these measurements, including operator technique and type of equipment, are identified. Comparisons also are given with skid resistance values obtained using a British portable pendulum tester. Outflowmeter measurements are presented to show the effect of surface finishes and treatments on drainage characteristics. The need to measure other surface texture parameters, such as microtexture, is suggested from comparative tire friction and surface macrotexture data obtained on two different wet surfaces. The paper concludes with comments relative to the necessity for additional studies to evaluate different surface microtexture measurement techniques in an effort to provide sufficient information to enable researchers to predict tire-pavement friction performance.
