“…In the second deposition step (475 to 600 ºC), this is associated with the end of the degradation of acrylonitrile. It was observed that between ~ 200 ºC and 325 ºC other decompositions occur; however, the reactions involved are volatiles that exist in the ABS [36][37][38], similar observations are also described in the literature [39][40][41][42].…”

ABS resins have wide application in the market, mainly in the manufacture of household appliances, telephones, automotive industry and others, and need to be processed by extrusion for the manufacture of products. The variables used in the process of extrusion of polymers have a direct influence on their mechanical properties. The objective of this study was to evaluate the different speeds of the extruder screw (15, 30, 45 and 60 rpm) on the mechanical properties of raw ABS after the extrusion process. Izod impact resistance and tensile tests, were also performed. The fractures of the samples tested by Izod impact were observed via optical microscopy, scanning electronic microscopy (SEM), and roughness was measured. Calorimetric tests (DSC) and thermogravimetry (TGA), as well as melt flow index (MFI), were also performed. The most significant results were observed for the extruder screw speed of 60 rpm. For the impact test, a reduction in impact energy of approximately 3% was observed, with the same result for tensile resistance. However, an increase in the value of the elastic modulus and the MFI was observed due to the increase in the degree of crystallinity, which was caused by the higher shear of the polymer mass in the screw of the extrusion equipment. Additionally, an atypical case occurred for the ABS polymer in the highest rotation, since it was the polymer that suffered the greatest shear in the polymer chains due to the degradation of the butadiene phase.

“…In addition to these, several other polymeric materials have shown promise. For example, the use of acrylonitrile butadiene styrene (ABS) plastic, known for its toughness and impact resistance, in asphalt mixtures can potentially enhance road durability in high-traffic areas [ 31 , 32 ]. Furthermore, research into utilizing polylactic acid (PLA), a biodegradable plastic, suggests that it could be used to increase the environmental sustainability of road infrastructures [ 33 ].…”

When navigating the environmental exigencies precipitated by global pandemics, the escalation of mask waste presents a multifaceted dilemma. In this avant-garde research, we unveil a novel approach: harnessing the sterilized shredded mask residues (SMRs), predominantly composed of 100 wt. % polypropylene, as pioneering modifiers for asphalt. Distinct proportions of SMR (e.g., 3, 6, and 9 wt. %) were judiciously integrated with fresh–virgin base AP-5 asphalt and subjected to an extensive suite of state-of-the-art examinations, encompassing thin-layer chromatography-flame ionization detection (TLC-FID), Fourier-transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), and specific rheological metrics. The TLC-FID diagnostic trajectories highlighted the nuanced rejuvenating influence of SMR on the binder, a facet reinforced by a pronounced elevation in the thermodynamic stability index (IC). The FT-IR spectra elucidated SMR’s preeminent role as a filler, negating notions of chemical reactivity. The TGA analyses unveiled an elevated thermal onset of degradation, signposting enhanced thermal resilience, whereas the DSC readings illuminated a superior thermal comportment at lower extremities. The SEM evaluations rendered a clearer panorama: there was heightened textural perturbation at escalated SMR incorporations, yet the 3 wt. % concoction showcased an optimal, coherent microtexture symbiosis with asphalt. The rheological scrutinies revealed a systematic trajectory: a diminishing penetration and ductility countered by ascending softening points and viscosity metrics. The coup de maître stemmed from the DSR analyses, unequivocally validating SMR’s unparalleled prowess in curtailing rutting distress. This seminal inquiry not only posits a blueprint for refined pavement longevity but also champions a sustainable countermeasure to pandemic-propelled waste, epitomizing the confluence of environmental prudence an d infrastructural fortitude.

Several research studies have been conducted on bitumen modification using solid waste materials. However, since textile waste contributes significantly to the formation of solid waste, more research is required on bitumen modification using textile waste. This study tried to modify bitumen using Textile Pyrolysis Oil (TXPO) and test its ageing properties. Pyrolysis oil was made by pyrolysing textile waste at 500°C. Textile Pyrolysis Oil Modified Bitumen (TXPOMB) was made by adding 1, 2 and 3% TXPO by weight of the Viscosity Grade 30 (VG30) bitumen and mixing in a high shear mixer. The binders are subjected to short-term ageing using a rolling thin film oven and long-term ageing using a pressure ageing vessel test in the laboratory. The effect of adding TXPO to a base binder and their oxidation process were investigated using Fourier Transform Infrared (FTIR) Spectroscopy. Chemical indices such as aromatic, aliphatic, carbonyl, and sulfoxide indices are calculated from FTIR spectroscopy to evaluate the effect of ageing. It was seen that 2% TXPO modification enhances the base binder's ageing resistance in both short and long-term ageing conditions. This modification not only addresses environmental concerns but also improves the performance and longevity of the bituminous materials.
