Abstract
Methods are provided for predicting the properties of an asphalt fraction that contains two or more asphalt components based on measurements of the viscosity versus temperature profile for the components of the asphalt fraction. The viscosity versus temperature profile for each component can be used to determine characteristic (such as limiting) values for the viscosity and temperature for a component. Based on this ability to determine characteristic values for an asphalt blend based on the properties of individual blend components, appropriate blends of asphalts can be selected in order to arrive at an asphalt blend with desired properties.
