The computer program for calculating solubility parameters is based on (a) elemental composition and aromaticity and (b) group (chemical functional groups) contributions. Solubility parameters for blended material are needed to generate phase behavior diagrams.
The key project objectives are:
(1) Develop a computer program for calculating solubility parameters of asphalts, asphalt components, and additives.
(2) Use solubility parameters to predict phase behavior tendency of asphalt and asphalt-additive blends.
The Solubility Calculator provides a good estimate of solubility parameters for binders and polymers; however, the values for most asphalt binders are nearly the same. The application will be much more useful when applied to asphalt components, such as maltenes (and their subfractions) and asphaltenes.
