“…The results in Figure 10 show that whatever addition of rubber occurs, with Terminal Blend procedure, Asphalt Rubber, and also using other warm mix additives or SBS, the modification of the binder leads to an extension of the range of the suitable temperatures (PG) of the bitumen. Only in one case it has been found that the high temperature (HG) PG of CRM modified binder decreased in comparison with the neat binder [50]. The authors showed that the PG grades of TB binders decreased with the increase of crumb rubber percentage (5%, 10%, 15%, and 20%) and the PG grades that resulted were lower than that of the traditional binder [50].…”

“…Principal acronyms of the modification process and technologies found in the literature that are useful for a better understanding of the results. CR + SBS + sulfur Crumb rubber modified binder with the further addition of SBS and sulfur [86] TB + SBS Terminal Blend modification of the binder with the further addition of SBS [50,78,88] TB + PPA Terminal Blend modification of the binder with the further addition of polyphosphoric acid [50] Figures 8-10 show the comparison between different CRM binders (TB, AR, CB, AR + WMA, DVR, CRM + RAP, RAP, CR + SBS, and CR + SBS + sulfur) and the traditional binder for certain standard properties. From Figure 8 it is possible to observe the comparison between different CRM binders with the traditional binder before the modification for different standard properties: viscosity, ductility, softening point and penetration.…”

“…Smaller particles facilitate degradation into the modified binder, nevertheless, the production of very fine particles is onerous and expensive. Therefore, the research has still focused on the use of bigger particles, eventually with the addition of additives (polymers and nanomaterials) for improving the binder properties [50,75,76]. See also Figure 6.…”

Tire rubber recycling for civil engineering applications and products is developing faster, achieving increasingly higher levels of maturation. The improvements in the material circle, where crumb rubber, generated as a by-product of the tire rubber making process, becomes the resource used for the construction of road asphalt pavement, is absolutely necessary for increasing the sustainability of the entire supply chain. The paper reports the results of an accurate data analysis derived from an extensive literature review of existing processes, technologies, and materials within construction of infrastructure. The current position, the direction, and rate of progress of the scientific efforts towards the reuse and recycling of tire rubber worldwide have been shown. Furthermore, an in-depth analysis of a set of important properties of Crumb Rubber Modified Asphalt has been carried out—fabrication parameters, standard properties, high and low-temperature performance, and rheological properties. Statistics over a sample of selected publications have been presented to understand the main processes adopted, rubber particle size, temperatures, and possible further modifications of crumb rubber modified binder.

“…However, previous studies found that DR‐modified asphalt (DRMA) has a weak high‐temperature performance . Therefore, to overcome these problems and guarantee the high‐temperature rutting resistance of the TB binder, the addition of modifiers such as styrene–butadiene–styrene or styrene–butadiene rubber is recommended …”

Desulfurized rubber (DR) and low-density polyethylene (LDPE) were used to modify bitumen. The basic physical properties, rheological properties, chemical composition, thermogravimetric behavior, and morphological characteristics were determined and evaluated to analyze the performance and mechanism of DR and LDPE compound-modified asphalt. A series of experiments (e.g., conventional test methods, rotational viscosity, storage stability, and dynamic shear rheometer tests), Fourier transform infrared spectroscopy, thermogravimetric analysis-differential scanning calorimetry, fluorescence microscopy, and atomic force microscopy were conducted. The results revealed that DR-modified asphalt (DRMA) had increases in the penetration, ductility, softening point, and penetration index by 30.2, 22.3, 3.5, and 11.1%, respectively, over the crumb rubber-modified asphalt (CRMA). The compatibility between the asphalt and modifier is better for DRMA than for CRMA. These findings indicate that DRMA has a better pavement performance than CRMA. Furthermore, compared with DR-modified bitumen, LDPE inclusions increased the value of G*/sin δ by at least 75.9% and improved the thermal properties. Morphological observations confirmed that the DR/LDPE additives were better dispersed than crumb rubber and formed a more homogeneous phase separation in the asphalt.
