A SKID RESISTANCE STUDY OF GEORGIA PAVEMENTS

THE CHARACTERISTIC SKID RESISTANCES OF THREE BLENDS OF AGGREGATES (ALL LIMESTONE, GRANITE COARSE AND LIMESTONE FINE, AND LIMESTONE COARSE AND GRANITE FINE) ARE EVLAUATED IN BOTH PORTLAND CEMENT CONCRETE AND ASPHALT CONCRETE PAVEMENTS. CONCLUSIONS INCLUDE: (1) THE LIMESTONES PRODUCED LOWER SKID RESISTANCE VALUES THAN OTHER AGGREGATE TYPES; (2) THE SKID RESISTANCE PROPERTIES OF PORTLAND CEMENT CONCRETE DEPENDS SIGNIFICANTLY ON THE FINE AGGREGATE USED; (3) IN THE ASPHALTIC CONCRETE MIXES TESTED, THE COARSE AGGREGATES, RATHER THAN THE FINES, HAD THE MOST SIGNIFICANT EFFECT ON SKID RESISTANCE AND (4) FOR COMPARABLE AGGREGATE COMBINATIONS, THE PORTLAND CEMENT CONCRETE SPECIMENS WERE MORE RESISTANT TO POLISH THAN THE ASPHALTIC CONCRETE SPECIMENS. /AUTHOR/
