“…However, in the last decades, 5-6% polymer amounts have become more common (Kalantar, Karim, & Mahrez, 2012). However, in the case of crumb rubber, it is possible to add higher amounts (up to about 20%) in the modification process (Kök & Çolak, 2011;Lo Presti, 2013;Sarang, Lekha, Krishna, & Ravi Shankar, 2016). Based on these references, the main range of polymer contents was defined, and different motor oil contents were evaluated.…”

The reuse of waste materials in asphalt mixtures has been recently investigated, in order to develop new sustainable solutions for the road-paving industry. Such materials should improve the mechanical performance and provide safe/comfortable pavement surface courses for road users, without compromising their environmental performance. Thus, the aim of this study is to evaluate the mechanical, surface and environmental properties of stone mastic asphalt (SMA) mixtures produced with forward-looking asphalt binders incorporating waste materials. These binders were designed to maximise the waste material content using motor oil, high-density polyethylene, styrene-butadiene-styrene and crumb rubber, while performing so well as a commercial modified bitumen. Finally, the overall performance of the SMA mixtures produced with the selected binders was evaluated. It was concluded that these mixtures improve the water sensitivity, fatigue cracking and permanent deformation performance. The requirements for macrotexture, skid resistance and presence of heavy metals in leachates of these mixtures were similarly fulfilled. Thus, this work shows that new asphalt mixtures with waste materials can be used in road-paving works to improve the performance without compromising human and environmental safety.

“…Aggregates of approximately 1200 g were for that reason used in the preparation of this specimen which was 101.6 mm in diameter with the breadth of around 63.5 mm of unadulterated bitumen. Moreover, the average amount of bitumen relevant in the preparation of the mixture was ascertained by this method [7]. It is equally imperative to note that the Marshall Stability was utilized in the prediction of the performance degree of stability of the mixture, the capacity of weight carrying as well as the permanent deformation resistance.…”

This study focuses on evaluating the resistance of polymer modified asphalt mixes and the role played by asphalt in the realm of construction is undeniably important. Addition of polymers(PB) as additives to asphalt helps to improve the strength and water repellent property of the mix and as well as helps environment in various ways and at the same time, analyzing its lower maintenance activities and service life is most important. The use of inexpensive polymers, in this case, waste polymers has without any doubt proven to be the most convenient way of reducing the cost of construction and at the same time maintaining quality. The main resolve for this research was to establish the effects of the use of plastic bottles on hot asphalt and its mixtures. In order to put this into perspective, varying percentages of asphalt mixtures were calculated and subjected to laboratory tests. The two-factor variance analysis (ANOVA) was conducted to determine the significance at various confidence limits. The results indicate that the inclusion of Polyethylene Terephthalate (PET) had a particularly substantial effect on the properties of asphalt. Consequently, it can encourage the re-utilization of waste in the manufacturing industry in an ecologically friendly and cost-effective way.

“…The SGC method is popular because the samples formed by gyratory compaction are well correlated with the field core. Sarang et al [7] formed SMA mixtures with shredded waste plastics by the SGC method, and studied their road performance. Muniandy et al [8] introduced a new type of automatic rotary compactor and evaluated its ability to compact SMA.…”

In this study, stone mastic asphalt (SMA-13) mixtures were designed using three methods, namely the vertical-vibration testing method (VVTM), Marshall method, and superpave gyratory compactor method (SGC). The performances of SMA-13 designed by all three methods were measured and compared. Results show that the optimal asphalt content of the asphalt mixture was 5% lower in the VVTM-designed SMA-13 than in the Marshall-designed and SGC-designed asphalts mixture. In comparison with the Marshall- and SGC-designed asphalts mixture, the VVTM-designed SMA-13 exhibited higher density (2.4% and 2.2% increase, respectively), mechanical properties (32% and 13% increase, respectively), high-temperature rut resistance (30% and 8% increase, respectively), low-temperature crack resistance (20% and 17% increase, respectively), water stability (4% and 3% increase, respectively), and fatigue life (at least 33% and 9% increase, respectively). The VVTM-designed SMA-13 exhibited a deeper short-term aging degree than the other SMA-13 specimens, but a smaller long-term aging degree. In summary, the SMA-13 mixture designed by the VVTM method delivered a better road performance and durability than the traditional design method, enabling improved designs of SMA mixtures.
