TEMPERATURE-VISCOSITY RELATION OF ASPHALTS USED IN THE UNITED STATES
VISCOSITY DATA ARE PRESENTED ON ASPHALT CEMENTS PRODUCED IN THE UNITED STATES FOR USE IN HIGHWAY CONSTRUCTION. ALL PROPERTIES WERE STUDIED BY THE BUREAU OF PUBLIC ROADS TO PROVIDE INFORMATION ON THE PROPERTIES OF ASPHALT PRODUCED FROM VARIOUS CRUDE SOURCES AND BY METHODS OF REFINING IN CURRENT USE. STATES HAVE DIFFERENT SPECIFICATION REQUIREMENTS FOR FUROL VISCOSITY AT CERTAIN TEMPERATURES. FUROL VISCOSITY TESTS WERE MADE ON THE ASPHALTS OF THIS STUDY. THE FUROL VISCOSITY OF 119 ASPHALTS RANGES FROM 85 TO 318 SECONDS. FOUR ASPHALTS HAVE VISCOSITY VALUES LESS THAN 100 SECONDS, WHILE TWO ASPHALTS MORE THAN 300 SECONDS. VISCOSITY OF 80 ASPHALTS IS WITHIN THE RANGE OF 150 TO 250 SECONDS. IT WAS CONCLUDED THAT THE VISCOSITY VARIES GREATLY AND THIS PROPERTY SHOULD BE RECOGNIZED IN PLANT MIXING OF ASPHALTIC MIXTURES, SPREADING AND COMPACTING OF THE MIXTURES ON THE ROAD, AND APPLICATION OF ASPHALTS BY SPRAYING.
