Crack-healing cycle via microwave heating. Research Project FONDEF VIU 20P0022 on self-healing asphalt mixture using metal dust waste and induction heating technology. This project aims to develop and validate a self-healing asphalt mixture demonstrator prototype in the laboratory using blast furnace dust and electromagnetic induction heating tests.

Self-healing process of a microcrack into an aged bitumen by the action of biobased spore microcapsules. Research published in “Biobased spore microcapsules for asphalt self-healing, ACS Applied Materials & Interfaces, 2022 14 (27), 31296-31311”. This paper proposes the use of extremely resistant biobased spores for the encapsulation of recycled oil-based rejuvenators to produce more resilient self-healing asphalt pavements.

Interview in CNN Chile about our FONDECYT Regular Research Project 1190027 on self-healing of bituminous materials using renewable resource-based microcapsules. 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 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 bottom-up design the materials, fully characterising them and evaluating their actual production.
