MEASUREMENT PRINCIPLES APPLIED TO SKID TESTING

STANDARD PAVEMENT TYPES AND EXPERIMENTAL SURFACES ON ROADS THROUGHOUT KENTUCKY WERE EVALUATED IN TERMS OF SKID RESISTANCE AND EFFECTS OF TRAFFIC, WEAR, AND POLISHING. FRICTION-VERSUS-SPEED GRADIENTS AND THE RELATIONSHIPS BETWEEN LOCKED-WHEEL AND INCIPIENT FRICTION WERE DETERMINED. ASPHALTIC CONCRETE PAVEMENTS ON HIGH-SPEED, FOUR-LANE ROADS WERE FOUND TO BE SIGNIFICANTLY MORE SKID RESISTANT THAN ON TWO-LANE HIGHWAYS AND SOMEWHAT MORE SKID RESISTANT THAN CONCRETE SURFACES (ESPECIALLY THOSE CONTAINING CALCAREOUS GRAVEL AGGREGATES). SAND-ASPHALT SURFACES CONTAINING SIGNIFICANT PROPORTIONS OF LIMESTONE SANDS SHOWED INADEQUATE LEVEL OF FRICTION FOR THE TRAFFIC SUSTAINED. SEVERAL EXPERIMENTAL SAND ASPAHLTS WITHOUT LIMESTONE SANDS EXHIBITED GREATER SKID RESISTANCE; KENTUCKY ROCK ASPHALT SURFACES REMAIN THE MOST SKID RESISTANT OF ALL SURFACES INVESTIGATED. /ASTM/
