This paper investigated the rheological performance of the combination of ethylene methyl acrylate and glycidyl methacrylate—EMA-GMA (reactive polymer)—and high-density polyethylene (HDPE) associated with polyphosphoric acid (PPA116%) in the modification of an asphalt binder (PG 64-XX). Tests such as performance grade (PG), multiple stress creep and recovery (MSCR), linear amplitude sweep (LAS), and master curve vary the EMA-GMA and PPA116% contents to obtain an ideal composition to provide a high-performance asphalt binder and thus compare with an unmodified asphalt binder and a styrene-butadiene-styrene (SBS) modified asphalt binder. The results showed that the asphalt binder stiffness improved as the EMA-GMA and PPA116% content increased. The PG temperature increased with the addition of PPA116% content in the asphalt binder samples, being most significant with the use of 1.8% of EMA-GMA. The addition of the combined polymers decreased the susceptibility to rut and improved the elastic recovery of the asphalt binder PG 64-XX, but only the samples with 1.8% EMA-GMA showed higher elastic recovery than the SBS-modified binder. PPA116% provided benefits in damage resistance at all strain levels; however, more was observed in samples subject to minor strains. The incorporation of 1.8% EMA-GMA, 0.3% HDPE, and 0.5% PPA116% was the one that presented the most improvements, without presenting gelation, in the performance of the asphalt binder in relation to stiffness and elasticity with increasing temperature. Thus, the use of these polymers in this composition can be a good alternative to regions with high temperatures, such as the northeast region of Brazil.

“…As seen in this study, each performance test and binder characteristic showed a different ranking of binders and there is no clear method in identifying a recommended rejuvenator combination. Recent literature has used performance diagrams to identify better performing asphalt binders (50,51). Performance diagrams include several different parameters that are plotted simultaneously.…”

“…The performance diagram in this study contained eight parameters—R-value, crossover temperature, G-R, LPG Cont , HPG Cont , ΔT c , carbonyl index, and sulfoxide index—as the goal of this study was to assess the susceptibility of rejuvenated RAP binders to aging. Therefore, all parameters, except HPG Cont and LPG Cont , were taken as the change in performance between the RTFO and PAV40 aging levels, which is similar to methods used to assess aging in literature ( 50 ). As mentioned previously, all the combinations were scaled to be values between 0.0 and 1.0 following Equation 3.…”

Rejuvenators are used in the asphalt industry to improve the performance and durability of aged binders and facilitate the use of recycled asphalt materials. The purpose of this study was to evaluate the impact of rejuvenator type and dose on the laboratory performance of asphalt binders. For this study, recycled asphalt pavement (RAP) and extracted RAP binder were obtained from an airfield reconstruction project located in Atlantic City, NJ. One petroleum-based (aromatic extract) and three organic-based (corn oil, tall oil, and modified vegetable oil) rejuvenators were evaluated in this study. Each rejuvenator was used at two different rejuvenator doses (6% and 12% by total RAP binder weight) and was aged at three different levels. Performance grade testing, frequency sweep tests, critical temperature differential (ΔTc ), and Fourier transform infrared spectroscopy (FTIR) tests were conducted. Results showed that the use of rejuvenators lowered the high and low performance grade of extracted RAP binders, in particular organic-based rejuvenators had a greater impact on the performance grade. ΔT c was also improved through the use of rejuvenators. In fact, the extracted RAP binder exceeded the high severity ΔTc threshold (−5°C), whereas the rejuvenated RAP binders improved ΔT c to values greater than the low severity threshold (−2.5°C). Similar findings were observed from the Glover-Rowe parameter as well, in which rejuvenated RAP binders improved the cracking resistance of the extracted RAP binder. When assessing the aging susceptibility, modified vegetable oil and corn oil rejuvenators showed the smallest change in performance between aging levels.

“…Many studies available investigated the effects of modified asphalt containing waste plastics at various dosages on its properties and pavement performance. The dosage range of common polymer-modified asphalt is between 2.5 wt% and 3.5 wt%, with a higher dose range greater than 7 wt% being referred to as highly modified asphalt [ 115 ]. Mashaan et al [ 28 ] reported that the ideal content of waste plastic is 6–8 wt% to improve the rutting and aging resistances of modified asphalt.…”

The use of waste products in the production of asphalt binders and asphalt mixtures has become widespread due to economic and environmental benefits. In particular, the use of recycled waste plastic in asphalt binders and mixtures is gaining more attention. This review presents analyses and comparisons of various forms of waste plastic used in asphalt modification, and approaches to incorporating waste plastic into asphalt mixtures, both for single and composite modifications. It focuses on the properties of waste plastics, asphalt binders, and asphalt mixtures. Overall, the incorporation of plastic waste into asphalt mixtures can significantly improve high-temperature performance and has potential economic and environmental benefits. The performance of modified asphalt is highly dependent on multiple factors, such as waste sources, waste plastic dosages, blending conditions, and the pretreatment methods for waste plastic. There are different ways to apply waste plastics to blend into a mixture. In addition, this paper discusses the current challenges for waste plastic-modified asphalt, including the stability, low-temperature performance, modification mechanism, and laboratory problems of the blends. The use of chemical methods, such as additives and functionalization, is considered an effective way to achieve better interactions between waste plastics and the binder, as well as achieving a higher sufficiency utilization rate of waste plastics. Although both methods provide alternative options to produce waste plastic-modified asphalt with stability and high performance, the optimal proportion of materials used in the blends and the microcosmic mechanism of composite modified asphalt are not clear, and should be explored further.
