INTERIM REPORT ON FRICTIONAL CHARACTERISTICS OF PAVEMENT SURFACES

RESEARCH WAS CONCERNED WITH THE MEASUREMENT OF PAVEMENT SLIPPERINESS AND THE SEARCH FOR MEANS TO ANTICIPATE THE RATE OF CHANGE OF THIS CHARACTERISTIC. THE STOPPING DISTANCE METHOD WAS USED FOR OBTAINING THE CONDITION OF THE PAVEMENT SURFACES. THESE MEASUREMENTS WERE MADE AT SPEEDS RANGING FROM 30 TO 60 MPH ON TEN SECTIONS OF ROADS IN THE STATE. DECELEROMETER MEASUREMENTS WERE ALSO MADE. THE TEST SITES WERE SAMPLED FOR 6-INCH DIAMETER CORES WHICH WERE THEN TESTED IN THE LABORATORY FOR SURFACE FRICTION AND SURFACE TEXTURE. ALL SKIDDING MEASUREMENTS WERE MADE ON WET PAVEMENT SURFACES. PRELIMINARY STUDIES OF DATA INDICATE THAT THE SURFACES TESTED HAVE MORE THAN ADEQUATE RESISTANCE TO SKIDDING. AT THE PRESENT, SUFFICIENT DATA HAVE NOT BEEN OBTAINED TO SHOW RELATIONSHIPS BETWEEN LABORATORY AND FIELD FRICTION VALUES TO ESTABLISH THE RATE OF FRICTION DETERIORATION FOR THE TEST SITES. /AUTHOR/
