RHEOLOGY OF ASPHALT CEMENTS AT 60 C (140 F)

STUDIES ON THE VISCOSITY OF 18 ASPHALTS AT 60 C (140 F) SHOWED THAT THE RESULT DEPENDS UPON THE APPARATUS AND PROCEDURE USED. THE FLORIDA CAPILLARY METHOD AT CONSTANT SHEAR RATE GIVES SIGNIFICANTLY HIGHER VALUES THAN DOES THE CANNON-MANNING METHOD. FURTHERMORE, IT WAS SHOWN THAT, ALTHOUGH SHEAR THINNING MAY RESULT FOR CERTAIN ASPHALTS WHEN RUN IN CANNON-PRESSURE INSTRUMENTS, THERE MAY ALSO BE COMPENSATING EFFECTS OF PRESSURE WHICH CAN RAISE THE VISCOSITY. THESE VARIATIONS ARE ATTRIBUTED TO BOTH DIFFERENCE IN THE FLOW MODE (TRANSIENT OR STEADY STATE) AND TO EFFECTS OF THE IMPOSED PRESSURES. /AUTHOR/
