Evaluation of Waste Bottle Crates in the Form of Pyro-Oil and Fine Granules as Bitumen Rejuvenators and Modifiers

This research study aims to investigate the feasibility of incorporating high-density polyethylene waste (HDPEW) into bitumen applications. Two conventional conditions bitumen, namely, aged (AB) and virgin (VB), are rejuvenated modified, respectively, using post-consumer HDPEW sourced out bottle crates. The outcome (Pyro oil, PO-HDPEW) pyrolysis thermochemical process is used by 10, 20, 30% rejuvenate AB, while fine-ground granules (FG) (FG-HDPEW) 2, 3, 4, 5% modify VB with different percentages. Physical rheological characterization testing, including penetration, softening point temperature, rotational viscosity (RV), conducted evaluate performance HDPEW-rejuvenated -modified binders optimize both rejuvenator modifier In addition, physical chemical tests, scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), Fourier transform infrared (FTIR) analyze composition, distribution surface contaminants, molecular structure based on their respective wavelengths. Moreover, advanced mechanical dynamic shear rheometer (DSR), multiple stress creep recovery (MSCR), linear amplitude sweep (LAS) susceptibility modified rutting fatigue cracking. testing results demonstrate that addition PO-HDPEW AB FG-HDPEW modification can enhance physical, chemical, mechanical, properties bitumen; however, this recommends further aging PO-HDPEW-rejuvenated bitumen. provides insights as a cost-effective eco-friendly properties, which aid in longevity pavements.
