PROOF OF CONCEPT OF A NOISE-REDUCING BIOASPHALT FOR URBAN ROADS
PDC2025-165400-I00
Funded by MICIU/AEI /10.13039/501100011033
The URBIFALT project aims to validate, under real-world conditions, the low-noise bio-asphalt mixture previously developed within the Low3Roads project, progressing from laboratory-scale development to its implementation in a pilot road section. To this end, its long-term ageing behaviour will be investigated, its durability and functional performance under in-service conditions will be assessed, and the challenges associated with industrial scale-up will be analysed.
Furthermore, the project will quantify the environmental and economic benefits of this solution, laying the groundwork for its future implementation as a sustainable alternative for creating healthier and more resilient urban environments.
Development of an accelerated ageing method specifically tailored to bio-binders, incorporating real environmental factors such as UV radiation and moisture to more accurately reproduce their long-term behaviour.
Assessment of the durability and mechanical performance of the low-noise bio-asphalt mixture through accelerated testing using GITECO's Circular Road Simulator (CRS). The results will enable the estimation of its service life and comparison with conventional asphalt mixtures.
Construction of a pilot road section under real-world conditions to validate the technology's performance, assess its traffic noise reduction potential, and identify potential barriers and risks associated with its production and implementation at an industrial scale.
Conducting a Life Cycle Assessment (LCA) and a cost-benefit analysis to quantify the environmental and economic advantages of the proposed solution compared with conventional road pavements, while also considering its benefits for public health and well-being.
Development of activities aimed at exploiting project results, including market assessments, business models, and SWOT analysis, with the active involvement of public authorities, road managers, and industry stakeholders to facilitate the adoption of the technology.
TheURBIFALT project participated in the European Researchers’ Night, a science outreach initiative that brings research and innovation closer to society through activities, demonstrations and workshops. During the event, the project team presented its objectives and explained how the development of new materials and technologies can contribute to more sustainable roads.
