Özet
Recently, many studies have been carried out on the use of waste materials in bitumen modification. In this way, environmental and economic benefits are obtained and a field of use is created for waste materials. In this study, magnesium lignosulfonate (MLS), which is an organic waste material released during paper production from wood, was added to B50/70 bitumen. Penetration, softening point, rolling thin film oven test (RTFOT) and rotational viscometer (RV) tests were performed on modified binders. As a result of the experiments, it was determined that MLS increased the consistency, softening point and short-term aging resistance of the asphalt and decreased the temperature sensitivity. In addition, the activation energy values were determined using the Arrhenius equation and the flow properties were evaluated.
