An Innovative Practical Approach to Assessing Bitumen Compatibility as an End Means of Material Specification

The project will include an application specific optimization tool for binder formulation; at present, such tool is considered severely impractical. There is need for this high-risk high-reward innovative research that can fill the current knowledge gap and provide a practical tool that can be readily implemented. The application of this work would not be limited to hot-mix asphalt pavements. A similar knowledge gap exists for preservation treatments, specifically for spray applied rejuvenators, whereby chemical compatibility between the existing pavement and the rejuvenator is usually unknown. Similarly, for cold recycling applications, the compatibility between the emulsion or foamed asphalt and RAP is not evaluated due to lack of a characterization method. Another potential application would be in specification of tack coat materials (especially for bonded pavement construction), whereby the asphalt emulsion properties are only controlled in terms of emulsion’s physical properties and emulsifier ionic characteristics.
