This case study will focus on the technological developments for recovery of pure concrete fractions and their ultimate use as raw material in the maintenance of road infrastructure (for example in the application of concrete overlays).
The overall objective of this case study is to assess and demonstrate the technical feasibility, economic viability and environmental sustainability of the innovative concrete recycling routes developed at TU Delft, which are in alignment with RE & CE principles, allowing for the validation and refinement of the model developed in WP3.
