Adhesion Multiphysics of Rubberised Asphalt Binders

Descripción del proyecto

Estudio de los mecanismos de adhesión de aglutinantes modificados con caucho

El uso de aglutinantes modificados con caucho triturado contribuye a mejorar las propiedades de adhesión y cohesión del betún asfáltico de grado estándar. En el proyecto AMRAB, financiado por las Acciones Marie Skłodowska-Curie, se modelizará la adhesión en la zona interfacial entre estos aglutinantes y agregados minerales en diferentes condiciones ambientales. Sus investigadores se proponen desarrollar un marco de predicción preciso y un protocolo de evaluación de las propiedades adhesivas de los aglutinantes modificados con caucho triturado, además de aplicar promotores de adhesión industriales al betún asfáltico cauchutado. Se espera que el uso de promotores y tecnologías de adherencia prolonguen la vida útil de las carreteras, aumenten la tasa de reciclaje de neumáticos de desecho y, en último término, reduzcan las emisiones nocivas relacionadas con la producción de betún asfáltico a partir de derivados de combustibles fósiles.

Objetivo

AMRAB aims to train a talented research Fellow through an interdisciplinary project focused on modelling the coupled adhesion multiphysics in the interfacial zone between crumb rubber modified binders (CRMB) and mineral aggregates under various environmental conditions. The primary deliverables of the project include a fundamental understanding of adhesion mechanisms, an accurate prediction framework and evaluation protocol for the adhesive properties of CRMB, and an implementation of industrial adhesion promoters and technologies in rubberised road construction. The Fellow will receive intensive technical training from both academic and industrial hosts, which will substantially extend his expertise from construction asphalt materials to a multidisciplinary field of chemistry (UoN), mechanics and computational modelling (Aston and KTH), experimental characterisation (UoN and RWTH) and road engineering applications (Total and AI). The Fellow will also receive inter-sectoral and professional skills training in project management, outreach, networking, and intellectual property protection. The benefits brought by AMRAB is represented by strengthening the EU industry leadership in adhesive material innovation and aiding the EU engineers in rubberised asphalt material selections, road structural design, and techno-economic analysis. The implementation of adhesion promoters and technologies for CRMB in rubberised road infrastructures will extend the road service life, increase the recycling of waste tires, and ultimately reduce the greenhouse gas emissions and consumption of petroleum bitumen. Uniquely, the project will enable the Fellow to obtain interdisciplinary knowledge and inter-sectoral complementary skills by building a new and exciting research field, which will pave a solid foundation for the Fellow towards his career of being an independent expert researcher in the areas of infrastructure sustainability and construction materials at a top European university.
