PREDICTION OF SKID-RESISTANCE GRADIENT AND DRAINAGE CHARACTERISTICS FOR PAVEMENTS
FOR SLICK PAVEMENTS, THE MAJOR FACTOR INFLUENCING THE ONSET OF SKIDDING OR HYDROPLANING IS SURFACE TEXTURE. TO EVALUATE THE EFFECTIVENESS OF THIS PARAMETER IN SPECIFIC INSTANCES, A SIMPLE INSTRUMENT CALLED AN OUTFLOW METER HAS BEEN DESIGNED, CONSTRUCTED, CALIBRATED, AND TESTED. THE OUTFLOW METER NOT ONLY COMPARES THE RELATIVE DRAINAGE ABILITIES OF SURFACES BY ASSIGNING A DRAINAGE NUMBER TO EACH , BUT ALSO SERVES TO ESTABLISH THE SLOPE OF THE WET SLIDING COEFFICIENT OF FRICTION VS SPEED CHARACTERISTIC FOR A PARTICULAR TEXTURE. IN THIS MANNER, PERIODIC TESTING OF PAVEMENT SECTIONS THAT HAVE MARGINAL SLIPPERINESS WILL INDICATE WHEN RESURFACING IS NECESSARY. ALSO, THE EXTENT OF LOCKED-WHEEL SKID TESTING IS DRASTICALLY REDUCED BY THE INSTRUMENTS DESCRIBED HEREIN. /AUTHOR/
