“…Another finding was that the amount of VA fraction in EVA contributed to the difference in the behaviour of a modified binder. Several reports have indicated the shift from a more thermoplastic to elastomeric behaviour due to the increase in VA content, which alters binder stiffness and softening point, as well as improves its elongation capacity [23]- [25]. All these effects can be explained by looking at the reaction mechanism inside the modified binder, where the polymer will absorb the lighter maltene fraction from the bitumen to form a polymer-rich phase.…”

The application of polymer in an asphalt concrete (AC) mixture has reached wide popularity lately to deal with the increasing demand for higher quality roads with heavier traffic loading. Ethylene-vinyl acetate (EVA), classified as a thermoplastic, is currently one of the most popular polymers employed. This research attempts to evaluate the effect of adding EVA by means of the dry method, namely by pouring the additive directly into the mixture, which produces both hot and warm Polymer-Modified Asphalt Concrete (PMAC) mix. FTIR result indicates the polymer as a thermoplastic material. Moreover, the volumetric and mechanical properties of the mixture were examined through the density and semi-circular bending (SCB) tests. The outcomes show that the inclusion of the polymer could slightly modify the density and VMA of the AC mix. Meanwhile, the tensile strength, fracture energy, crack resistance index (CRI), and flexibility index (FI) results describe substantial enhancement brought by the polymer, with a generally increasing trend up 200% of the control mix. Conclusively, the application of polymer could enhance the physical and mechanical properties of hot and warm AC mixes with the optimum dosages of 5 and 6%. Additionally, the properties of warm PMA are somewhat comparable to the regular hot AC mix.

“…Se considera que la capa es el principal origen de la formación de los surcos, su susceptibilidad también está influenciada por las interacciones de agregado-asfalto y la proporción de vacíos en los agregados minerales (Rahi, Fini, Hajikarimi, y Nejad, 2015). Razón por la cual, las superficies de asfaltos a base solo de betún no pueden proporcionar las propiedades físicas y mecánicas necesarias para su durabilidad (Yadykina, Navolokina, y Gridchin, 2020). Por ello frente a este problema los ingenieros se han centrado en mejorar el rendimiento del asfalto mediante la adición de polímeros (Celauro, Bosurgi, Sollazzo, y Ranieri, 2019).…”

En los últimos años se ha visto afectada la infraestructura vial debido al incremento del tráfico y las variaciones de temperatura, esto ha ocasionado la aparición de surcos y grietas. El presente trabajo tiene como objetivo realizar una revisión sistemática de la literatura sobre el uso de etileno vinil acetato (EVA) en mezclas asfálticas. Se realizó una revisión de 50 artículos científicos indexados entre los años 2015 al 2021, recopilados de distintas de datos obtenidas de Scopus, Sciencedirect, ProQuest, IOP Science y Ebsco. Sobre la revisión se encontraron investigaciones de la influencia de EVA en las propiedades del asfalto. Se examinó el proceso de selección de contenido óptimo, los cambios en las propiedades y los resultados obtenidos. Se pudo concluir que la adición de EVA mejora las propiedades, incrementa la estabilidad, disminuye la formación de los surcos y las deformaciones.

“…В предыдущих исследованиях авторов [8] для повышения качества вяжущего был использован сэвилен (СЭВА), содержащий 14-29% винилацетата (ВА). Наилучшие результаты получены при введении в битум СЭВА с 22% ВА, но полученное полимерно-модифицированное вяжущее не удовлетворяло требованиям ГОСТ по показателю растяжимости.…”

Rutting is an important problem in Russia today. One of the ways to improve the properties of asphalt concrete mixtures and reduce wear on road surfaces is to modify the binder with polymer additives. The aim of the work was to test the selected compositions of MMAC mixtures containing bitumen modified with the addition of sevilene and rubber for rutting resistance, which make it possible to predict the formation of plastic rut. It was revealed that when using sevilen in its composition, with an increase in the concentration of vinyl acetate, the depth of the track increases in comparison with the industrial polymer-bitumen binder. It is shown that with the introduction of a complex additive based on sevilen and rubber into the binder composition, its rutting decreases and the service life of the road surface increases, which indicates a high elasticity of the complex-modified binder. In this work, the calculation of the service life of the coating before the formation of a critical rut requiring repair of the coating is carried out. It was found that in terms of the slope of the rutting curve and the proportional depth of the rut, the compositions with sevilene and rubber are not inferior to traditional industrial PBB.
