SKID RESISTANT PAVEMENTS IN VIRGINIA

THE PREVIOUSLY PUBLISHED WORKS OF MOYER, SHELBURNE, SHEPPE, AND OTHERS ARE REVIEWED ON THE SUBJECT OF SKID RESISTANCE CHARACTERISTICS. THE PAPER DISCUSSES SEVERAL DIFFERENT METHODS OF TEST, AND DESCRIBES THE METHOD MOST COMMONLY USED IN VIRGINIA, THE MEASUREMENT OF THE STOPPING DISTANCE OF A PASSENGER CAR WITH WHEELS LOCKED. A DISCUSSION OF THE FACTORS AFFECTING THE ACCURACY OF THIS METHOD IS INCLUDED. THE RESULTS OF STOPPING DISTANCE TESTS MADE AT SEVERAL HUNDRED LOCATIONS IN VIRGINIA ARE PRESENTED. THESE TEST RESULTS ARE TABULATED IN DIFFERENT WAYS TO INDICATE, SO FAR AS POSSIBLE, THE EFFECTS OF AGE, TRAFFIC, AND MOST PARTICULARY, THE TYPE OF AGGREGATE USED IN THE MIX. THE DATA POINT VERY STRONGLY TO WHAT IS FELT TO BE A RATHER SERIOUS LACK OF SKID RESISTANCE ON THE PART OF MOST BITUMINOUS AND EVEN PORTLAND CEMENT CONCRETE PAVEMENTS WHEN CONSTRUCTED WITH LIMESTONE AGGREGATES. A DESCRIPTION OF THE EXPERIMENTAL PROGRAM DESIGNED TO DETERMINE ECONOMICAL WAYS OF PROVIDING NON-SKID PAVEMENTS IS GIVEN. THE PURPOSE OF THE EXPERIMENTAL PROGRAM WAS (1) TO FIND ECONOMICAL WAYS OF DESLICKING EXISTING ROADS, AND (2) TO FIND ECONOMICAL WAYS OF BUILDING-IN PERMENANT HIGH SKID RESISTANCE AT THE TIME OF CONSTRUCTION. SKID TEST RESULTS ON THE EIGHT EXPERIMENTAL SECTIONS ARE PRESENTED AND DISCUSSED. THE CONCLUSIONS REACHED ARE TENTATIVE PENDING ADDITIONAL SERVICE LIFE. /AUTHOR/
