DESLICKING TREATMENT WITH ASPHALTIC SLURRY /IN PORTUGUESE/

SKID RESISTANCE MEASUREMENTS TAKEN ON THE RIO-SAO PAVLO HIGHWAY ARE PRESENTED. THESE MEASUREMENTS WERE TAKEN IN 1970, BEFORE AND AFTER THE APPLICATION OF A BITUMINOUS OVERLAY OF AN ASPHALTIC SLURRY, ON A STRIP WHERE MANY ACCIDENTS OCCURRED DUE TO THE SLICK WEARING COURSE. THE ASPHALTIC SLURRY MIXTURE WAS USED TO OBTAIN A COARSE SURFACE, AND QUARTZ GRAINS WERE ADDED TO GIVE A GOOD WEAR RESISTANCE. THE MIXTURE WAS COMPOSED OF: SAND (92% IN WEIGHT), PORTLAND CEMENT (8% IN WEIGHT), WATER (18% IN WEIGHT OVER 100% OF AGGREGATE), EMULSION RL-IK (47% IN WEIGHT OVER 100% OF AGGREGATE). /RRI/
