“…The asphalt binder was first heated in a container until it became fluid, and then when it reached 170-190°C the SBR1502 and LDPE were added. The mixing time was 60 min and the mixing speed was 4,000 rpm in the laboratory (Kim, Mazumder, Lee & Lee, 2018;Mazumder et al, 2020;Liang et al, 2021).…”

“…: styrene isoprene styrene (SIS), styrene butadiene styrene (SBS), and plastomers, e.g. : ethylene-butyl acrylate (EBA) and polypropylene (PP) polyethylene (PE) (Al-Hadidy & Yi-Qiu, 2009;Mazumder, Siddique, Ahmed, Lee & Lee, 2020;Alghrafy, El-Badawy & Abd Alla, 2021;Babagoli, 2021;Che et al, 2022). According to various research, the mixing temperature for a homogeneous blend should range from 150° to 230°C, with a typical range of 175-200°C, for a period of 30 min to 4 h. The temperature at which the blend becomes a homogeneous polymer with asphalt solution is directly related to the asphalt binder's polymer concentration and asphaltenes content (Ahmed & Al-Harbi, 2014;Babagoli, 2021).…”

The influence of styrene butadiene rubber (SBR) or low-density polyethylene (LDPE) polymers on the characteristics of local asphalt binder was analyzed to characterize the rheological properties. The results indicated that the SBR or LDPE increased the softening point. The softening point was enhanced by around 35% when 9% of SBR was used in comparison to the unmodified asphalt, while there was a 15% increment when LDPE was used. The results also indicated that the SBR or LDPE decreased the penetration rate. The penetration decreases by around 36% when 9% of SBR is used compared to the neat asphalt, while a significant increment was 89% when 9% of LDPE is used. Additionally, when 9% SBR was employed, the ductility of the asphalt binder rose by roughly 73%, but 64% less ductility was seen when 9% LDPE was utilized. Finally, the addition of the additive has improved the penetration index, thus reducing the temperature sensitivity. Due to said above, SBR and LDPE are practical and promising modifiers that will be useful in enhancing the performance of the asphalt binder straightforwardly and efficiently.

“…As a modifier, SIS increases the viscosity and improves the rutting resistance of asphalt binder [10,11]. Due to the increase in viscosity, the stiffness of SIS-modified asphalt binders consequently increases, which may cause thermal and fatigue cracking [12].…”

Characterization of Sustainable Asphalt Binders Modified with Styrene–Isoprene–Styrene (SIS) and Processed Oil

The current study aims to evaluate the viscosity and rheological properties of PG 64-22 modified with Styrene–Isoprene–Styrene (SIS) and Processed Oil (PO) to enhance asphalt binder properties. Performance properties were measured at high, intermediate, and low temperatures. PG 64-22 was blended with SIS and Processed Oil at three levels (5%, 10%, and 15% by weight of binder) and two concentrations (6% and 12% by weight of binder), respectively. Modified binders underwent two short and long artificial aging processes, through the spinning of the thin film in an RTFO oven and a pressure aging vessel (PAV). The Superpave binder evaluations were carried out using a rotational viscometer (RV), dynamic shear rheometer (DSR), and bending beam rheometer (BBR). According to the findings of the research, the addition of SIS caused higher values of viscosity, but when co-modified with processed oil, there was a substantial decrease in viscosity values. As a result, workability was improved. (1) It was observed that a greater reduction in viscosity was achieved when the processed oil was present at a higher concentration at 135 °C compared to a lower concentration. (2) The study showed that the incorporation of processed oil led to a reduction in rutting performance of the asphalt binder. However, the addition of SIS resulted in a notable enhancement of rutting resistance. (3) The role of processed oil as co-modifier at concentrations of 6% and 12% caused significant decreases in G*sin δ, based on the susceptibility of asphalt molecules to accept oil molecules in their network links. (4) The extracted measurements from the BBR tests indicated that modification with SIS and PO improved the low-temperature cracking resistance significantly. Comparison of asphalt binders modified with 6% and 12% PO and the same SIS content showed significant changes in modification with 12% PO rather than 6%.

“…In fact, it has been successfully proven that polymer-modified asphalts (PMAs) can greatly boost the road pavement's performance. Several types of polymers have been favored, including random copolymers (e.g., ethylene-vinyl acetate (EVA) copolymers [3] and styrene-butadiene random (SBR) copolymers) [4], homopolymers (e.g., ethylenepropylene-diene (EPDM) [5], high-density polyethylene (HDPE) [6], low-density polyethylene (LDPE) [7], and polyisobutylene (PIB)) [8], and triblock copolymers (e.g., styreneisoprene-styrene (SIS) [9], styrene-butadiene-styrene (SBS) [10], and their hydrogenated forms). PMA cannot only decrease damask and thermal sensitivity, but also increase the resistance against rutting, fatigue, and cryogenic cracks.…”

From Street to Road: An Innovative Approach to Explore Discarded Chewing Gum as a Performance-Enhancing Modifier for Road Pavement Applications

2021

To uncover the potential benefits of discarded chewing gum (DCG) as a performance-enhancing modifier for road pavement applications, its influence on the asphalt binder’s attributes was profoundly examined. The base AP-5 asphalt along with its specimens dosed with various fractions of DCG (e.g., 3, 6, and 9 wt%) were analyzed by Fourier transform-infrared spectroscopy (FT-IR), X-ray diffraction (XRD), thin-layer chromatography-flame ionization detection (TLC-FID), scanning electron microscopy (SEM), atomic force microscopy (AFM), thermogravimetric analysis (TGA), and differential scanning calorimetry (DSC). Brookfield viscometer, ring and ball softening point, needle penetration, and dynamic shear rheometer (DSR) tests were adopted to inspect the physical and rheological changes of asphalt cement after DCG incorporation. FT-IR disclosed that the asphalt-gum interaction was not chemical but physical in nature, whilst XRD demonstrated the existence of talc filler in DCG, which may confer the bituminous mixes with exceptional engineering properties. Iatroscan analysis evinced that the gum treatment particularly altered the aromatic and resin fractions; meanwhile, the content of saturates and asphaltenes remained relatively unchanged. SEM divulged that the DCG has a complete dissolution within the bitumen matrix, which becomes rougher due to higher dose administration. AFM revealed that the steady gum introduction amplified the size of bee-like structures, shrunk their peri-phase domains, and wiped out the para-phase domains entirely. TGA/DTGA/DSC data highlighted that the high-temperature-stable additive slightly affected the thermal properties of blends. DSR and empirical rheological tests showed that the waste gum made the bitumen less vulnerable to heat and tender, thereby boosting its resistance against fatigue cracking at intermediate service temperatures. On top of that, DCG widened the thermal window of bitumen performance grade (PG), and preserved its viscosity at standard temperatures, leading to maintaining an appropriate workability for asphalt mix. In brief, the use of discarded chewing gum as an asphalt modifier is feasible and could mitigate plastic pollution and provide durable roadways by delivering superior performance.
