SKID RESISTANCE OF PAVEMENTS
This publication contains information on various parameters which were considered to be of primary influence relative to skid resistance variation. Considerable data is presented on the dynamic repeatability and statistical variance of the measuring unit as a system. Environmental and physical variables which include pavement temperature, two vehicle cab temperature and humidity, season, water discharge rate, transverse pavement variation and speed gradient data are discussed. An analysis based on two years of controlled testing on a Portland Cement Concrete surface indicated the inherent repeatability error of the skid trailer as a system to be plus or minus .3 SN. A multiple regression analysis of the environmental variables specified accounted for only 39 percent of the variation encountered during the repeatability testing program. The lateral positioning of the test tire is extremely critical due to inherent pavement variation and wear. Differences as large as 20 skid numbers were noted on the randomly selected locations.
