“…To summarize, based on the numerous published papers, there are around 675 articles dealing with the recovery of tire wastes in concrete and/or mortar as aggregates (87% of these publications concern concrete while only 13% are on mortars). Moreover, according to some review papers dealing with the state-of-the-art on this theme (Al-Attar et al 2021;Qaidi et al 2021;Rashad 2016;Surehali, Singh, and Biligiri 2023), it appears that existing studies on concrete consider crumb rubber aggregates at percentages less than 30% by volume. Some works deal with replacements greater than 30% (Aiello and Leuzzi 2010;Alsaif et al 2018;Khaloo, Dehestani, and Rahmatabadi 2008;Marie 2016) and only few studies focus on total replacement (Atahan and Yücel 2012;Batayneh, Marie, and Asi 2008;Khaloo et al 2008;Marie 2016;Medina et al 2017).…”

In this study, seven mortar mixes were prepared by replacing natural sand by crumb rubber ,CR, (10%, 25%, 50%, 60%, 75% and 100%). The properties of mortars, both in their fresh and hardened states, were studied. Key characterisitcs, including density, water absorption coefficient, porosity, thermal conductivity, heat capacity, shrinkage/swelling, elastic modulus, compressive strength, flexure strength, fracture energy and performance after exposure to heat, were evaluated. The results obtained showed that as the CR fraction increased, density, initial setting time, and workability decreased but mortars with CR fractions ranged between 25% and 50% are lightweight and can be used for repairing as they fulfill satndards. It was observed that strengths and stiffness decreased with higher CR content while shrinkage increased for CR percentage higher than 60%. However, up to 50% of CR content the mortars obey to the standards for repair. Interestingly, incorporating up to 50% waste tires proved to improve comfort and thermal resistance without affecting thermal inertia. A slight increase in the mass loss is observed when mortars are exposed to high temperatures. Mortars containing CR between 25% and 50% can be classified as lightweight and thermally insulating mortars, suitable for repairing concrete structures in accordance with industry standards.

As two kinds of solid wastes, waste tires and steel slag have caused serious threats to the environment. Both waste tire rubber (WTR) and steel slag powder (SSP) can improve the performance of asphalt, while the performance indexes and modification mechanism of modified asphalt are not clear. In this paper, asphalt modified with SSP and WTR was prepared, and its performance was evaluated. The physical properties of asphalt modified with SSP and WTR, including penetration, the softening point, and viscosity, were investigated. Furthermore, high-temperature performance, fatigue resistance, low-temperature performance, and blending mechanism of asphalt modified with SSP and WTR were tested with a dynamic shear rheometer (DSR), bending beam rheometer (BBR), and Fourier transform infrared spectrometer (FTIR). The results showed that with the same content of WTR and SSP, WTR reveals a more significant modification effect on physical properties, fatigue, and low-temperature performance of base asphalt than SSP. The anti-rutting performance of SSP-modified asphalt is better than that of WTR-modified asphalt at 30~42 °C, and the anti-rutting performance of WTR-modified asphalt is better than that of SSP-modified asphalt at 42~80 °C. When the total content of WTR and SSP is the same, the physical properties, high-temperature resistance, fatigue resistance, and low-temperature performance of the asphalt modified with WTR and SSP decrease with the decrease in the ratio of WTR and SSP, and their performance is between WTR-modified asphalt and SSP-modified asphalt. Infrared spectrum results verified that the preparation of WTR- and SSP-modified asphalt is mainly a physical blending process. Overall, this research is conducive to promoting the application of modified asphalt with WTR and SSP in the construction of high-standard pavement.

“…Although many review papers have been published in recent years regarding recycling waste tire rubbers through their mixing with thermoplastic polymers, 24 thermoset polymers, 41 rubbers, 22 asphalt, 42,43 and concrete, [44][45][46] the research works about polystyrene/waste tire rubber, to the best of our knowledge, has not been reviewed to now. In the published works, different types of polystyrene, such as general-purpose polystyrene (GPS), high-impact polystyrene (HIPS), and expanded polystyrene (EPS), were blended with waste rubbers produced from various sources such as tires, shoes, and packaging articles.…”

Polystyrene (PS), as a commercial thermoplastic polymer, suffers from brittleness at low temperatures. Blending with elastomers can resolve this defect. In this regard, waste rubbers from tires, shoes, and other sources are promising candidates for some applications. This approach of waste rubber recycling is an environmental‐friendly and economical method to produce value‐added products. This work aims to comprehensively review all reported cases regarding PS (or high‐impact polystyrene, HIPS, and expanded polystyrene, EPS)/waste rubber blends. The influences of different parameters on the mechanical properties were carefully summarized, including mixing conditions (temperature, mixing time, rotor speed, and mixing sequence), rubber content, rubber particle size, compatibilizer addition, rubber devulcanization, and surface treatment of rubber. Some parameters had a negligible effect on the mechanical properties, such as the rotor speed in the mixing process, while significant influences were observed for some parameters, such as rubber content. The effect of some parameters was remarkable only at low or high rubber loading, such as particle size and solvent‐inducing surface treatment of rubber, respectively. Finally, the effects of aforementioned parameters on tensile and impact strengths were compared and recommendations for future research in this field were suggested.Highlights All reported research regarding PS/waste rubber blends was comprehensively reviewed. All different factors influencing mechanical properties were carefully summarized. The effects of different factors on tensile and impact strengths were compared.
