Abstract

Between december, 1958, and september, 1959, over 300 pavement surfaces, including 6 surface types, were skid tested in florida using a tapley decelerometer mounted in a passenger vehicle. The skid tests were conducted on a wet surface at 40 mph. A number of decelerometer tests were conducted simultaneously with stopping distance tests so that the results of the two methods could be compared. The results of this study indicated that the decelerometer method provides a convenient, economical, and reliable method for determining the skid resistance of pavement surfaces. The results obtained from the decelerometer tests appeared to correlate with results of stopping distance tests if certain testing techniques were used. Considering wet pavement surface with friction coefficients below 0.40 at 40 mph as being definitely dangerous, resurfacing programs were undertaken to eliminate hazardous areas. It was found that excellent improvements in skid resistance could be obtained using a chip seal. Also, considerable experimental work has been done using slurry seal as a remedy for slick and distressed pavements.
