Abstract

Multilayer plastic waste continues to increase due to the ever-growing consumption and needs of the global citizen and is one of the most challenging types of waste to recycling because of its nature. The accumulation and indiscriminate disposal of waste can pose a potential risk of environmental problems. A solution that can be implemented is to mix bitumen and waste polymer as asphalt manufacturing. Despite its advancement in research, many potential parameters are still to be discovered to achieve optimal results. Through cold plasma treatment, a surface treatment may occur at the multilayer polypropylene that causes the change from hydrophobic to hydrophilic properties. Treating the polymer with cold plasma will provide good hydrophilic properties without changing the overall chemical and thermal properties of the sample. This will result in an alternative aggregate for the bitumen for asphalt manufacturing. Bitumen coupled with the addition of plastic still provides an optimal hardness and ductility, meanwhile having a more economically viable manufacturing process than other processes.

Abstract

This study focuses on enhancing the performance and sustainability of asphalt materials in road construction by recycling High-Density Polyethylene (HDPE). Polypropylene (PP) and lignin as additives in bitumen. The Hot Melt Mixing method is employed to investigate the impact of different concentrations of HDPE, PP, and lignin on bitumen properties. Key properties such as ductility, penetration, softening point, and thermal behavior are analyzed, providing valuable insights into the potential of these additives to enhance bitumen performance. The findings demonstrate that higher concentrations of HDPE and PP result in reduced penetration depth, indicating increased hardness. The addition of lignin enhances penetration depth, contributing to the flexibility and performance of the bitumen mixture. Moreover, thermal analysis offers valuable information about the thermal behavior and stability of the bitumen-plastic-lignin blends, shedding light on their compatibility and interactions. This research contributes to the ongoing efforts in road construction and pavement engineering by exploring sustainable solutions that not only address plastic waste challenges but also improve the performance and durability of bituminous materials, making it a crucial step towards environmentally responsible and long-lasting asphalt pavements.
