PAVEMENT SLIPPERINESS IN TENNESSEE
THROUGHOUT MOST OF THE THREE-YEAR STUDY, SLIPPERINESS WAS MEASURED THROUGH THE USE OF A TWO-WHEEL TRAILER. AS A PRELIMINARY TO THE MAJOR INVESTIGATION, COMPARISONS WERE MADE OF SLIPPERINESS OF WET AND DRY PAVEMENTS, CLEAN AND DIRTY PAVEMENTS, AND SMOOTH AND RIBBED TREAD TIRES. IN ADDITION, THE EFFECT OF LOAD ON THE SLIDING WHEEL AND OF PAVEMENT AND TIRE TEMPERATURES WAS INVESTIGATED. A NUMBER OF PAVEMENTS WERE TESTED FOR ACTUAL STOPPING DISTANCE WITH AN AUTOMOBILE. A COMPARISON OF THE TWO METHODS OF TEST, TRAILER AND AUTOMOBILE, IS SHOWN. IT IS CONCLUDED THAT A MAJOR CAUSE OF PAVEMENT SLIPPERINESS IN TENNESSEE IS THE SUSCEPTIBILITY OF CERTAIN LIMESTONE AGGREGATES TO POLISH UNDER THE ACTION OF TRAFFIC. IT IS ALSO CONCLUDED THAT WHERE SUCH AGGREGATES ARE USED IN PORTLAND CEMENT CONCRETE PAVEMENTS THESE PAVEMENTS HAVE THE SAME POTENTIAL FOR BECOMING SLIPPERY AS DO BITUMINOUS PAVEMENTS CONTAINING THE AGGREGATES. IT IS APPRECIATED THAT THE POLISHING ACTION WILL TAKE A CONSIDERABLY LONGER TIME IN THE CASE OF THE CONCRETE PAVEMENTS THAN THE BITUMINOUS ONES. WITHIN THE LIMITATIONS OF THE EQUIPMENT EMPLOYED, IT IS CONCLUDED THAT STOPPING-DISTANCE TESTS PERFORMED ON A SERIES OF PAVEMENTS WILL RATE THEM WITH RESPECT TO SLIPPERINESS IN ESSENTIALLY THE SAME ORDER AS SKID TRAILER TESTS, PROVIDED SIMILAR TIRES ARE EMPLOYED AND THE TEST CONDITIONS STANDARDIZED TO THE GREATEST POSSIBLE DEGREE. /AUTHOR/
