A STUDY OF PAVEMENT SKID RESISTANCE AT HIGH SPEEDS AND AT LOCATIONS SHOWN TO BE FOCAL POINTS OF ACCIDENTS

THE FIRST PHASE OF THIS INVESTIGATION HAS BEEN CONCERNED WITH ESTABLISHING A CORRELATION BETWEEN THE SKID RESISTANCE OF A PAVEMENT'S SURFACE AND THE SURFACE TEXTURE AS DETERMINED BY A MODIFICATION OF THE METHOD USED BY SCHONFELD AND THE ONTARIO DEPARTMENT OF HIGHWAYS IN CANADA. OVER 70 LOCATIONS WERE SELECTED AS BEING REPRESENTATIVE OF THE SURFACE MIXES BEING USED IN THE STATE OF TENNESSEE. THE TEXTURES RANGED FROM A VERY FINE SAND ASPHALT SURFACE TO A VERY COARSE AND HIGHLY SKID RESISTANT SLAG AGGREGATE SURFACE COURSE. CORES WERE OBTAINED AT EACH OF THESE LOCATIONS AND EVALUATED IN THE LABORATORY TO DETERMINE THE PARAMETERS OR SURFACE TEXTRUE. EACH PARAMETER WAS ASSIGNED A FRICTION WEIGHT IN A SIMILAR MANNER TO THAT PROPOSED BY SCHONFELD. A HIGH DEGREE OF CORRELATION WAS OBTAINED WHEN COMPARING THE SKID RESISTANCE VALUES AS DETERMINED FROM THE SURFACE TEXTURE WITH THOSE OBTAINED BY FIELD MEASUREMENTS OF SKID RESISTANCE. AS MIGHT BE EXPECTED, THE AGGREGATE TYPE, SOURCE AND GRADATION WERE THE MAJOR FACTORS IN PROVIDING SURFACE TEXTURE WHICH WAS CONDUCIVE TO HIGH SKID RESISTANCE.
