Reutilization of Recycled Cellulose Diacetate From Discarded Cigarette Filters in Production of Stone Mastic Asphalt Mixtures

In this paper, recycled cellulose diacetate (rCDA) derived from cigarette butts was used as a fiber stabilizer to develop stone mastic asphalt (SMA) mixtures. The characterizations of rCDA were investigated by scanning electron microcopy (SEM), Fourier transform infrared spectrometer (FTIR), and thermogravimetric analyzer (TGA). Volumetric stability, temperature moisture fatigue performance SMA mixtures with tested obtain the pavement performance. Results showed that appeared have tough surface texture curly corrugated structure, which facilitated enhancement cohesion bond binder. TG-DTG indicated maximum weight loss (62.48%) obtained at temperatures ranging 294.1°C 376.0°C due decomposition degradation organic matters. When 0.4% in mixture, dynamic stability 4,105 cycles/mm. ultimate flexural strength stiffness modulus 3,722 MPa 9.7 MPa. It superior 0.3% polyacrylonitrile (PAN), while inferior polyester (PET). value tensile ratio residual Marshall 80.2 75.3%, respectively. life technically like PAN PET lower stress levels. All results concluded optimum content mass
