RELATION OF VISCOSITY GRADED ASPHALT CEMENTS TO MIXTURE BEHAVIOR AND PAVEMENT PERFORMANCE

AN ATTEMPT IS MADE TO DISCOVER THE MERITS OF GRADING BY VISCOSITY AT 14 OF RATHER THAN BY PENETRATION AT 77F FROM THE VIEWPOINT OF THE PERFORMANCE OF THE PAVEMENT. PERIODICALLY, FOUR TEST SECTIONS ARE EXAMINED BY REMOVING CORES SELECTED AT RANDOM AND TESTED FOR PENETRATION, VISCOSITY AND DUCTILITY. VARIOUS PIECES OF EQUIPMENT - NAMELY THE ROAD LOGGER, DYNAFLECT, PROFILOGRAPH, NUCLEAR MOISTURE PROBE, AND THE VARIABLE LENGTH STRAIGHT EDGE - ASSIST IN DETERMINING THE CONDITION AND SERVICEABILITY OF THE TEST SECTIONS. ANALYSIS OF VARIANCE PROCEDURES ARE USED TO EVALUATE THE DATA. /USHD/
