The biggest contributor to the energy consumption (up to 90% of the total) in the Asphalt plants is the fuel used for heating and drying the virgin aggregates in processing of Reclaimed Asphalt Planings (RAP). Proposed review evaluates the currently used technologies to process RAP into Asphalt mixtures. Theoretical comparison is conducted for all the technologies to obtain the effects they have on energy consumption, carbon emissions and costs. The proposed research will evaluate different technologies for RAP mixing and potential benefits technology can bring in terms of cost and greenhouse gas mitigation. Comparative analysis shows parallel drum dryer are most efficient and emit less greenhouse gas with comparison to other discussed technologies.
