REPORT OF COMMITTEE ON ANTI-SKID PROPERTIES OF ROAD SURFACES

THE SKID RESISTANCE OF 36 REPRESENTATIVE OREGON PAVEMENT SURFACES WAS DETERMINED BY MEANS OF A SPECIALLY CONSTRUCTED TRAILER TOWED BEHIND A LIGHT TRUCK. A DYNAMOMETER IN THE TOWING BAR MEASURED THE TRACTIVE RESISTANCE OF THE TRAILER WITH ONE WHEEL LOCKED, WHILE THE TRAILER WAS BEING TOWED AT ONE OF THE SEVERAL CONSTANT SPEEDS USED IN THIS INVESTIGATION. FOUR GENERAL TYPES, PORTLAND CEMENT CONCRETE, ASPHALTIC CONCRETE, BITUMINOUS MACADAM, AND OIL MAT, WERE TESTED. AGES OF PAVEMENTS RANGED FROM 18 YEARS TO THOSE NOT YET OPENED TO GENERAL TRAFFIC. SURFACE TEXTURE VARIED FROM OVERLY FAT ASPHALTIC CONCRETE TO NEW HEAVILY GROOVED PORTLAND CEMENT CONCRETE AND COARSE OPEN TEXTURED ASPHALTIC CONCRETE AND BITUMINOUS MACADAM. TESTS OF THE LENGTH OF SKID WITH WHEELS LOCKED OF A SEDAN ON ELEVEN TYPES OF PAVEMENT SURFACE IN CLEVELAND, OHIO, ARE ALSO REPORTED. THE STANDARD HYDRAULIC BRAKES ON THE CAR WERE ARRANGED FOR AIR OPERATION, AND THE LENGTH OF SKID WAS DETERMINED BY PISTOL SHOT MARKS ON THE PAVEMENT. /AUTHOR/
