Self-healing of bituminous materials using renewable resource-based microcapsules

Grant: FONDECYT Regular Research Project 1190027

Funding Agency: National Research and Development Agency (ANID), Chile

Principal Investigator: Jose Norambuena-Contreras (UBB)

Co-principal Investigators: Gonzalo Valdés Vidal (UFRO) & Luis E. Arteaga-Perez (UBB)

Project duration: 2019 to 2023 (48 months)

This project explores the use of more sustainable and economically viable solutions to repair cracked asphalt pavements by the action of biopolymeric microcapsules, where different renewable resource-based polymers are obtained from marine and lignocellulosic biomass waste, will be used as encapsulation materials for virgin and recycled rejuvenating agents. The adopted methodology will be experimental and numerical, combining material characterisation techniques with multi-scale modelling, as well as Life Cycle Assessments and Life Cycle Cost Analysis to the bottom-up design of the materials, fully characterising them and evaluating their actual production.
