EFFECTS OF PAVEMENT SURFACE CHARACTERISTICS AND TEXTURES ON SKID RESISTANCE

THE PURPOSE OF THE RESEARCH WAS TO DETERMINE THE RELATIONSHIPS BETWEEN SKID NUMBERS AND SMALL-SCALE TEXTURES COMBINED WITH MACROTEXTURE PARAMETERS. THE RESULTS OF THIS RESEARCH STRESS THE IMPORTANCE TO DRIVER SAFETY OF THE MICROTEXTURES AND THE SMALL-SCALE MACROTEXTURES OF AGGREGATE PARTICLES EXPOSED ON PAVEMENT SURFACES. THESE TEXTURES TOGETHER WITH THE MACROTEXTURES AS MEASURED BY THE PROFILOGRAPH AND THE DISTRIBUTION OF THE AGGREGATE SIZE HAVE A DECIDED INFLUENCE ON THE SKID NUMBER MEASURED BY A LOCKED-WHEEL TRAILER AND HENCE ON DRIVER CONTROL. THE RESULTS ALSO SHOW THAT LOW VALUES OF MACROTEXTURES ARE INDICATIVE OF POOR DRAINAGE FROM THE TIRE- PAVEMENT INTERFACE. LOW VALUES OF VOID AREAS RESULT IN LARGE REDUCTIONS IN SKID NUNBERS AS THE SKIDDING SPEED INCREASES. /AUTHOR/
