Analysis of waste polyethylene (PE) and its by-products in asphalt binder

The use of waste plastics in partial asphalt binder replacement and substitute for polymer modification has the potential to contribute sustainability road infrastructure as well preservation natural resources. In this study, two types polyethylene (PE) PE-pellets PE-shreds (a by-product former, currently incinerated after production) were blended with a conventional order analyze their effect on chemo-mechanical thermal behavior. Particular attention was paid characterization PE description sample preparation, lacking other studies. Differential Scanning Calorimetry (DSC), Thermal Gravimetric Analysis (TGA), Fourier Transform Infrared (FTIR) spectroscopy Environmental Electron Microscopy (ESEM) used assess different binder's properties, chemical degree quality blending, respectively. rheological performance obtained using Dynamic Shear Rheometer (DSR). results illustrated that compared commercial modified binders, resistance against high temperature distresses such rutting could improve substantially adding PE. modulus binders at low temperatures comparable. However, negative storage stability indicated needs be mixture preparation method.
