Evaluation of Viscosity Graded Asphalt Cements in Utah
Test sections were constructed to obtain an indication of the effectiveness of grading asphalts by viscosity. Tests indicate that the standard tests such as viscosity, penetration and ductility are of value as indicators of asphalt quality, but Force Ductility, viscosity vs shear rate, and Temperature Susceptibility are more effective. A chemical breakdown also is a good indicator of asphalt quality, and shows a difference in asphalts mainly dependant upon the source of crude. This difference in source has more effect on performance than does the viscosity grade. Generally, the 'softer' asphalts performed better in Utah's climate. Recommendations are made for desired asphalt properties.
