Abstract:To gain information on the appropriate temperature to obtain a given desirable viscosity for the various asphalt cements commonly used in Oregon, viscosities were determined at three or more temperatures near the mixing temperature. From the values determined by test, a plot of log-log viscosity vs. log absolute temperature can be used to predict the temperature associated with a specific viscosity value. To determine how these particular asphalts would fit the viscosity gradings proposed for asaphalt cement, the 140F viscosities were estimated by this method.
