CALIFORNIA SKID TESTS WITH BUTYL RUBBER TIRES AND REPORT OF VISIT TO ROAD RESEARCH LABORATORIES IN EUROPE ENGAGED IN SKID PREVENTION RESEARCH
RESULTS OF TESTS CONDUCTED IN 1962 ARE PRESENTED TO SHOW THE IMPROVEMENTS IN SKID RESISTANCE ON WET PAVEMENTS PROVIDED BY THE RECENTLY DEVELOPED BUTYL RUBBER TIRES. THESE TESTS MEASURED UNUSUALLY HIGH COEFFICIENTS OF FRICTION ON WET PAVEMENTS AFTER ABNORMALLY HEAVY RAINS AND TRAFFIC HAD SCOURED THE PAVEMENTS CLEAN AND PROVIDED A COARSE-GRAINED ABRASIVE SURFACE. TESTS ON THIS PAVEMENT, AND ALSO ON OTHER PAVEMENTS WHERE COEFFICIENTS OF FRICTION WERE MEASURED, REVEALED THE UNPRECEDENTED RESULT IN THE CALIFORNIA TESTS THAT THE COEFFICIENTS IN THE WET PAVEMENT TESTS WERE HIGHER THAN THE COEFFICIENTS ON THE SAME PAVEMENTS IN THE DRY PAVEMENT TESTS. THESE HIGH COEFFICIENTS REPRESENTED A MARKED IMPROVEMENT IN THE COEFFICIENTS OF FRICTION MEASURED ON CALIFORNIA PAVEMENTS OVER THE PAST 12 YEARS, PARTICULARLY DUE TO THE IMPROVEMENTS IN SKID RESISTANCE OF TIRES, IMPROVEMENTS IN THE TEST EQUIPMENT AND IN THE ACCURACY OF THE MEASUREMENTS, AND IN THE TYPE AND CONDITION OF THE PAVEMENTS TESTED.
