摘要: Abstract Approximately 30% of industrially produced ceramic materials worldwide are dumped as waste in landfills. Thus, these a major environmental concern. Reusing or recycling wastes for constructive purposes remains challenging. In this work, we evaluated the first time modified chemical and physical properties bitumen incorporated with inorganic nanoceramic powder (NCP) from wastes. Chemical morphological NCP were determined. Bitumen specimens characterized using transmission electron microscopy, X-ray fluorescence spectroscopy, diffraction, Fourier transform infrared atomic force microscopy (AFM). Physical rheological also examined by penetration, softening point, dynamic shear rheometer tests. Morphological analysis revealed formation an interaction between Si O stretching vibration hydrocarbon molecules. This resulted incorporation into unmodified matrix. The increased viscosity reassembled asphaltene particles. new sheet was generated, aromatic bonds (C C) strengthened. AFM results reaffirmed structural improvement bitumen. Furthermore, elasticity viscoelasticity its matrix increased. These improvements can be attributed to polyaromatic structure.
