HIGH SPEED SKID RESISTANCE AND THE EFFECTS OF SURFACE TEXTURE ON THE ACCIDENT RATE

THE CALIFORNIA STATE DIVISION OF BAY TOLL CROSSINGS HAS USED DENSE GRANDED EPOXY ASPHALT PAVEMENT FOR SURFACING TWO ORTHOTROPIC STEEL DECK BRIDGES AND OPEN GRANDED EPOXY ASPHALT PAVEMENT FOR RESTORING THE SKID RESISTANCE OF A DETERIORATED EPOXY COAL TAR CHIP SEAL PLACED ON A CONCRETE BRIDGE. IT HAS PROVED TO BE DURABLE, WITHSTANDING REPETITIVE FLEXURE, AND PROVIDING GOOD SKID RESISTANCE WHEN PLACED ON STEEL DECKS. IT ALSO HAS PROVED TO BE A DURABLE AND SKID RESISTANT PAVEMENT WHEN PLACED ON A CONCRETE DECK AS THIN AS 1/2 IN. TO LIMIT INDUCED DEAD LOAD STRESSES. THE THERMOSETTING EPOXY ASPHALT BINDER WILL NOT FLUSH TO THE SURFACE AND HOLDS THE AGGREGATE WITH A STRONG BOND THAT ALLOWS FULL EXPOSURE OF THE PARTICLE FACES. AGGREGATE THAT PROVIDES HIGH FATIGUE LIFE FOR ORTHOTROPIC STEEL DECKS WILL PROBABLY PRODUCE HIGH SKID RESISTANCE. SIXTEEN TEST SECTIONS OF PAVEMENT WERE PLACED IN LATE 1971 FOR SKID RESISTANCE EVALUATIONS. SIX OF THESE ARE DENSE GRANDED EPOXY ASPHALT PAVEMENTS. THE RESULTS TO DATE INDICATE GOOD DURABILITY AND GOOD SKID RESISTANCE. GRAPHS OF VARIATION OF SKID NUMBER WITH TIME ARE PRESENTED FOR TWELVE EPOXY ASPHALT PAVEMENTS. /ASTM/
