A STUDY OF THE USE OF VISCOSITY GRADED ASPHALT CEMENTS IN EXPERIMENTAL SECTIONS OF PAVEMENT

DATA ARE PRESENTED ON THE PROPERTIES OF MATERIAL AND CONSTRUCTION DATA OF NINETEEN ASPHALT CONCRETE TEST PAVEMENTS LOCATED IN FOUR RESURFACING PROJECTS OVER PORTLAND CEMENT CONCRETE PAVEMENTS. THE ASPHALTS USED VARIED IN PENETRATION GRADE (60/70, 70/85, 85/100, 90/105) AND VISCOSITY GRADE (AC6, AC12, AC24). THE PROPERTIES OF THE ORIGINAL ASPHALTS, ASPHALTS RECOVERED FROM PLANT AND PAVEMENT SAMPLES, CONSTRUCTION DATA, AND PROPERTIES OF THE PAVEMENTS ARE DOCUMENTED. FUTURE TESTING WILL BE DONE TO DETERMINE THE CHANGE IN PROPERTIES WITH INCREASED AGE AND CORRELATED WITH THE PROPERTIES OF THE ORIGINAL ASPHALTS AND PAVEMENT SERVICEABILITY. SKID TESTS DONE 10 TO 15 MONTHS AFTER CONSTRUCTION INDICATE THAT THE VISCOSITY OF THE ASPHALT CEMENT DOES NOT HAVE A MAJOR EFFECT ON THE SKID RESISTANCE OF A PAVEMENT. AFTER ABOUT 10 MONTHS OF SERVICE, VISUAL INSPECTION INDICATES THAT ALL TEST SECTIONS ARE IN GOOD AND SERVICEABLE CONDITION. ALL SECTIONS DO SHOW REFLECTIVE CRACKING FROM THE BASE PAVEMENT. /BPR/
