Improving performance of recycled asphalt applications with bitumen and asphaltenes mix

New innovative technology is proposed for Recycled Asphalt Shingles (RAS) to produce cold mix asphalt (CMA) for dust control in unpaved roads. This novel method will design a mix of bitumen/RAS/water emulsions that break in a controlled manner upon field application. The effect of asphaltenes, petroleum solvents, emulsifier type, concentration and properties, and the preparation conditions, such as agitation speed, temperature, and the order in which components are added on the performance of the emulsions will be evaluated. Considering the large amount of asphalt shingles and residual feedstock in Canada, the success of this project helps Synchor Recycling Inc.
to commercialize this technology and sell a high price RAS-based cold mix which will increase their revenue that can later be leveraged to further advance this project. Further, the project turns solid waste, like asphalt shingles, into value added product, thus making the RAS process sustainable and environmentally friendly.
