TEN YEARS OF RESEARCH IN NEW YORK STATE ON THE SKID RESISTANCE OF ASPHALT PAVEMENTS IS SUMMARIZED. SKID NUMBERS MEASURED BY A TWO-WHEELED TRAILER ARE RELATED TO CUMULATIVE VEHICLE PASSES FOR THE STATE'S GEOLOGIC FORMATIONS, WHICH ARE SOURCES OF COARSE AGGREGATE FOR ASPHALT CONCRETE. MIXES WITH COARSE AGGREGATE CONTAINING AT LEAST 20 PERCENT NONCARBONATE STONE - OR 10 PERCENT SAND-SIZED IMPURITIES EMBEDDED IN A CARBONATE MATRIX - REMAIN SKID RESISTANT FOR THE LIFE OF THE PAVEMENT. SPECIFICATIONS HAVE BEEN WRITTEN TO REQUIRE AGGREGATES NOT MEETING THESE REQUIREMENTS TO BE UPGRADED BY BLENDING THEM WITH 20 PERCENT NONCARBONATE STONE. /AUTHOR/
