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.}, number={1}, publisher={Fırat University}
