Investigating the Multi-Recyclability of Recycled Plastic-Modified Asphalt Mixtures

Although the benefits of asphalt recycling have been scientifically proven and several best practices are being implemented, further research is required in specific specialized areas. One these circumstances Reclaimed Asphalt Pavements (RAPs) that contain modifiers such as elastomers and/or plastomers. Following principles circular economy considering sustainability implications mixtures, this paper deals with multi-recyclability mixtures containing 50% RAP without a recycled plastic modifier rejuvenating agent. The was made hard plastics introduced to mixture via dry method. focuses on characterization binders conventional, rheological, chemical analysis. To control consistency variables produced artificially laboratory following an ageing protocol for loose mixtures. According obtained results, at all three cycles binder recycling, comparable properties (i) extracted from plastic-modified mixture, (ii) un-modified (iii) reference bitumen 50/70 were obtained. This even noticed when nearly similar quantity rejuvenator needed during optimization process. Overall, it can be deduced binder-scale point view, additive could multiple life any degradation its mechanical physical properties.
