    The effect of waste material generated during paper production on the rheological and structural features of asphalt binder

    Yilmaz, Bahadir; Ugurlu, Nuray

    In this study, the performance properties of magnesium lignosulfonate, an organic waste material produced during paper production from wood, on asphalt binder were investigated. The modification was carried out by adding magnesium lignosulfonate (MLS) at 2%, 4%, 6%, and 8% by weight to the asphalt with B50/70 penetration grade. The morphological structure, modification mechanism, and thermal decomposition temperatures of the modified asphalt binders formed by adding the MLS to the asphalt were determined by a Scanning Electron Microscope (SEM), Fourier Transform Infrared Spectroscopy (FT-IR), and Thermogravimetry-Differential Thermal Analysis (TG/DTG), respectively. The physical and rheological properties of the material were determined by penetration, softening point, Rolling Thin Film Oven Test (RTFOT), Dynamic Shear Rheometer (DSR), and Rotational Viscometer (RV) experiments conducted in a laboratory. The experimental results showed that the organic-based waste additive increases the asphalt consistency, rutting, and short-term aging resistance, and decreases the temperature sensitivity.

    Investigation of Reuse by Recycling Asphalt Pavements in Hot Mix Asphalt

    Yilmaz, Bahadir; Oruç, Seref; Mazlum, Mehmet Salih

    In many countries of the world, waste management becomes compulsive with activation of laws and agreements about waste control. By this purpose, it becomes necessary and imperative to use waste asphalt materials as raw material for the new asphalt pavement due to economic advantages of using old materials, decreasing of the raw material’s potential, and problems of researching new asphalt raw mines and increasing of the asphalt pavement cost. Within this scope, this work has started to a research of re-used old materials which are completed their economic life on the road in the hot bituminous mixes. In this work, recycling methods that are used in World and Turkey are analyzed at the beginning and the advantages of recycling are utilized. İstanbul region is chosen as the working area and materials are gained by the roads that completed their economic life in İstanbul. By these materials, new coverable mix materials had produced in different ratios such as10%,25% and40%. Marshall Experiment had used to these mixtures, intensity and void analyses are made and the results that obtained from experiments are compared with the pure materials and the core samplers
