description This study evaluated the antioxidant properties of red grape pomace and its benefits as an additive for asphalt binder. The samples were modified using red grape pomace as an antioxidant agent in concentrations of 1%, 2% and 3%. These samples were left outdoors to undergo natural oxidation for 12 weeks. Another set of samples were aged in an ultraviolet radiation (UV) chamber to compare the results between both oxidation methods. Three functional groups were taken in consideration to measure the degree of oxidation: the carbonyl, the carbon-carbon double bond and the sulfoxide indexes. The asphalt modified with 3% red grape pomace had the lowest increase in carbonyl index, showing that the additive works as an agent to delay the oxidation process in asphalt. The indexes obtained for the field aged samples were significantly larger than the ones associated to the UV chamber, consequently aging in a UV chamber did not properly emulate environmental conditions. Further research analyzing higher percentages of red grape pomace (greater than 3%) to understand the effect of larger contents of additive is recommended.

Se modificó asfalto con orujo de uva roja en porcentajes de 1%, 2% y 3% como agente antioxidante. Las muestras preparadas se expusieron a oxidación natural a la intemperie durante 12 semanas. Adicionalmente, las muestras se envejecieron en un horno de radiación ultravioleta (UV) para comparar con el envejecimiento experimentado a la intemperie. El grado de oxidación se estimó a partir de espectroscopía infrarroja, tomándose tres grupos funcionales como parámetros de referencia: índice de carbonilos, índice de dobles enlaces carbono-carbono e índice de sulfóxidos. El asfalto modificado con 3% de orujo tuvo el menor incremento del índice de carbonilos con respecto a los otros asfaltos, indicando que este porcentaje logra retardar la oxidación en comparación con el asfalto sin modificar. Los índices asociados al material colocado en la intemperie resultan ser mayores que los obtenidos en el horno UV, por lo que se concluye que este método aún no simula correctamente la oxidación en la intemperie. Por estos motivos, se recomienda realizar una investigación con porcentajes de orujo mayores al 3% para determinar el efecto del aditivo a mayores concentraciones y realizar modificaciones el método de oxidación con radiación UV en laboratorio.UCR2021-01-25info:eu-repo/semantics/publishedVersionArticleartículo originalhttp://purl.org/coar/resource_type/c_2df8fbb1info:eu-repo/semantics/articleapplication/pdftext/htmlhttps://revistas.ucr.ac.cr/index.php/vial/article/view/4441910.15517/iv.v23i41.44419Infraestructura Vial; Vol. 23 No. 41 (2021): Issue 41, February-June 2021; 1-10Infraestructura Vial; Vol. 23 Núm. 41 (2021): Revista 41, Febrero-Junio 2021; 1-10Infraestructura Vial; Vol. 23 N.º 41 (2021): Revista 41, Febrero-Junio 2021; 1-102215-37051409-404510.15517/iv.v23i41reponame:Portal de Revistas UCRinstname:Universidad de Costa Ricainstacron:UCRspahttps://revistas.ucr.ac.cr/index.php/vial/article/view/44419/45864https://revistas.ucr.ac.cr/index.php/vial/article/view/44419/45903Derechos de autor 2021 Rojas, Aguiar-Moya, Arias-Barrantes, Baldiacceso abiertohttp://purl.org/coar/access_right/c_abf2info:eu-repo/semantics/openAccess2021-06-09T19:43:42Zoai:portal.ucr.ac.cr:article/44419Portal de revistashttps://revistas.ucr.ac.cr/Universidadhttp://www.ucr.ac.crhttps://revistas.ucr.ac.cr/index.php/index/oaijorge.polanco@ucr.ac.crCosta RicaNo aplicaNo aplicaNo aplicaopendoar:2025-08-13T10:30:54.337Portal de Revistas UCR - Universidad de Costa Ricafalse
