Summary: In this study, a covalent adaptable network based on the thermoreversible cross-linking of an ethylene-propylene rubber through Diels-Alder reaction was prepared through melt blending. The research shows that this rubber has the potential to compete with conventionally cross-linked elastomers and can be recycled through a simple melt processing step. Furthermore, the addition of reduced graphene oxide to the thermoreversible rubber significantly improves its stiffness and thermal conductivity.

Summary: The study showed that CRM absorption can hinder the attack of oxygen on bitumen, maintaining a softer environment around the swelling rubber and improving the aging resistance of AR. The incorporation of WMA additives affected the rheological properties of AR but did not compromise its aging resistance.

Summary: This study demonstrates the blending of rigid polyester PU and soft polyether PU using twin-screw extrusion to produce materials with tunable mechanical properties. The extruded materials exhibit similar mechanical and thermal properties to freshly prepared blends, and higher-value mechanical properties compared to samples reprocessed via compression molding. Additionally, the extruded materials show less phase separation in morphology compared to compression-molded blends, and the mechanical properties were tunable through consecutive reprocessing cycles.

Summary: This paper discusses the preparation of thermoreversibly crosslinked composite rubbers that are industrially viable and environmentally sustainable. A maleimide-functionalized silica (Sil-M) is used as a reinforcement filler and crosslinking agent on furan-grafted ethylene-propylene rubber (EPRgF) via Diels-Alders reaction. The composite rubbers are prepared by reactive melt blending without using organic solvents. Mechanical properties are compared between EPRgF/Sil-M and unfunctionalized EPRgF/Sil to show the impact of DA crosslinking. The study also investigates the combination of Sil-M and bismaleimide to optimize crosslinking and material performance.

Summary: Fatigue cracking has been a crucial constraint for the development of reclaimed asphalt pavements due to the performance of rejuvenated asphalt binder. This study investigated the fatigue properties of waste rubber/oil (WRO) rejuvenated asphalt and universal rejuvenated asphalt through dynamic shear rheometer test. It was found that N-p20, corresponding to the mutagenesis of phase angle, is a physically significant evaluation index for fatigue life of rejuvenated asphalt. The fatigue performance of WRO rejuvenated asphalt was superior to universal rejuvenated asphalt, especially at high loading frequencies and levels.

Summary: Thermoplastic elastomers based on ground tire rubber are effective for recycling waste tire rubber. This study focuses on optimizing parameters such as rubber concentration and dispersion, as well as crosslinking degree, to produce valuable TPE. The addition of a compatibilizer improved the interfacial interactions between the rubber and plastic, resulting in improved mechanical properties and processability for the TPE.

Summary: Pyrolytic carbon black (CBp) is the main by-product of waste tire pyrolysis. In order to improve its surface activity and dispersion, the effect of different surfactants on the properties of CBp/natural latex rubber composites was investigated. The experimental results showed that the composites modified with C18H29NaO3S and C8H7NaO3S surfactants exhibited better dispersion and physical/mechanical properties than those modified with C17H35COONa. The C18H29NaO3S modified composite had the highest tensile strength and the C8H7NaO3S modified composite had the lowest loss factor (tand) value.
