PAVEMENT MATERIAL PROPERTIES AS RELATED TO SKID RESISTANCE

SKID RESISTANCE AT 20 MPH AND 50 MPH AS OBTAINED WITH A TWO-WHEELED SKID TEST TRAILER WAS STUDIED IN RELATION TO VARIOUS PAVEMENT MATERIALS PROPERTIES WHICH INCLUDE PAVEMENT TYPE, AGGREGATE TYPE, AGGREGATE SHAPE, AGGREGATE GRADE, AGGREGATE HARDNESS, PAVEMENT TEXTURE AND ASPHALT OR CEMENT CONTENTS. IT WAS FOUND THAT THE AVERAGE INITIAL FRICTION WAS ABOUT THE SAME FOR EACH PAVEMENT TYPE, BUT PORTLAND CEMENT CONCRETE PAVEMENTS GENERALLY REVEALED A SMALLER WEAR OR POLISH RATE. AGGREGATE TYPE WAS FOUND TO BE IMPORTANT FOR FLEXIBLE PAVEMENT SURFACES AND THE LOS ANGELES WEAR TEST RESULTS WERE FOUND TO BE RELATIVELY UNIMPORTANT FOR EACH PAVEMENT TYPE STUDIED. BINDER CONTENT, AGGREGATE GRADE AND AGGREGATE SHAPE WERE FOUND TO DEPEND ON THE PAVEMENT TYPE. A STATISTICAL ANALYSIS USING MULTIPLE REGRESSION TECHNIQUES RESULTED IN A POOR CORRELATION WHEN MATERIALS PROPERTY VARIABLES WERE RELATED TO FRICTION. /AUTHOR/
