SKID RESISTANCE OF SCREENINGS FOR SEAL COATS
PROVIDING AND MAINTAINING A SKID-RESISTANT SURFACE IS A VERY IMPORTANT FACTOR IN THE PERFORMANCE OF ANY HIGHWAY. ALL TYPES OF PAVEMENT SURFACES WILL EVENTUALLY SHOW SOME REDUCTION IN COEFFICIENT OF FRICTION VALUES DURING THEIR SERVICE LIFE. THIS REDUCTION IS CAUSED BY WEAR AND POLISH OF TRAFFIC. A SATISFACTORY METHOD HAS BEEN DEVISED FOR DETERMINING IN THE LABORATORY THE ORIGINAL COEFFICIENT OF SEAL COAT SCREENINGS BY USE OF FABRICATED TEST PANELS AND THE CALIFORNIA SKID TESTER. FRICTION VALUES OBTAINED FROM THE TEST PANELS CORRELATE VERY WELL WITH FIELD TEST INSTALLATIONS. A LABORATORY METHOD FOR WEAR AND POLISH STUDIES HAS BEEN DEVELOPED WHICH SHOWS GOOD CORRELATION WITH ACTUAL SERVICE PERFORMANCE OF SCREENINGS. /AUTHOR/
