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.
