Comparison of performance characteristics for asphalt concrete mixtures with 40 % reclaimed asphalt and different binder solutions
Original language description
Asphalt pavement recycling by using reclaimed asphalt material back in a new asphalt mixture is a commonly known solutions which has been gradually developed during the last 40 years. Nevertheless the recycling rates are in many countries still rather limited. The reasons are restrictions in technical standards, necessary investments in the asphalt mixing plants or disbelief in the equal quality of asphalt mixtures containing reclaimed asphalt if compared to regular asphalt mixtures. Asphalt recycling becomes even more challenging if increased rates of reclaimed material shall be used or if such material should be added to asphalt mixtures containing polymer modified binders. For this reason an experimental study has been done (as the first step prior to a larger trial section following in 2018), where different technical solutions on asphalt concrete are going to be compared - rejuvenation, soft paving grade bitumen and a so called RC polymer modified bitumen. Regular empirical tests as well as more advanced performance characteristics have been determined and evaluated (stiffness, thermal induced cracking, flexural strength, asphalt ageing impact). Selected results are presented in the paper.
