SKID RESISTANCE TESTING FROM A STATISTICAL VIEWPOINT

STANDARDS OF MINIMUM SKID RESISTANCE FOR HIGHWAY PAVEMENTS MUST BE COMPATIBLE WITH THE LIMITATIONS OF LOCKED-WHEEL SKID TESTERS AND SKID RESISTANCE CHARACTERISTICS OF THE HIGHWAYS. VARIANCE OF SKID TESTING DATA ARISES FROM THE TESTERS, TEST TIRES, AND PAVEMENTS. THE MAGNITUDE OF EACH SOURCE IS ILLUSTRATED, AND SOME OF THE CAUSES ARE EXPLAINED. THE INFLUENCE OF THE VARIANCE IS EXAMINED WITH RESPECT TO THE CONFIDENCE OF SKID TEST DATA IN REPEAT AND SURVEY MODES; THE POINT IS MADE THAT A LARGE NUMBER OF TESTS SHOULD BE CONDUCTED WHENEVER POSSIBLE. IT IS CONCLUDED THAT THE REDUCTION OF VARIANCE DUE TO THE TESTER AND THE TEST TIRE, THOUGH DESIRABLE, WILL NOT ELIMINATE THE NEED FOR STATISTICAL METHODS IN SKID TEST DATA ANALYSIS. THE WAY IN WHICH MINIMUM SKID RESISTANCE STANDARDS SHOULD BE DEFINED IS DISCUSSED AS IS A PROPOSED METHOD BY WHICH STATISTICAL UNCERTAINTY CAN BE REFLECTED IN THE INTERPRETATION OF RESULTS FROM SURVEY TESTING.
