SKID RESISTANCE OF PAVEMENTS-INTERIM REPORT

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-VS-SPEED GRADIENTS AND THE RELATIONSHIPS BETWEEN LOCKED-WHEEL AND INCIPIENT FRICTION WERE DETERMINED. CLASS I BITUMINOUS 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 CALCAEROUS GRAVEL AGGREGATES). SAND-ASPHALT SURFACES CONTAINING SIGNIFICANT PROPORTIONS OF LIMESTONE SANDS SHOWED INADEQUATE LEVEL OF FRICTION FOR THE TRAFFIC SUSTAINED. SEVERAL EXPERIMENTAL SAND ASPHALTS WITHOUT LIME SANDS EXHIBITED GREATER SKID RESISTANCE; KENTUCKY ROCK ASPHALT SURFACES REMAIN THE MOST SKID RESISTANT OF ALL SURFACES INVESTIGATED. /AUTHOR/
