These CERCOM case studies will test the validity of the risk-based approach developed in WP3 over a range of technical areas (new material applications, recycling, and innovative technologies) at different levels of development and maturity.

A sensitivity analysis will be undertaken to evaluate the robustness of the model results, identify the model boundaries (sensitivity to uncertain parameters), and assess the availability and reliability of the input data. The analysis of the case studies will uncover the difficulties and highlight the opportunities for the implementation of RE & CE principles.

Case study I: Maintenance options for asphalt pavements

This case study aims to assess the technical, economic and long-term environmental viability of several technologies that align with the principles of RE & CE.

Case study III: Decarbonising pavement maintenance

A key element of the sustainability goals underpinning the highways sector is the need to reduce emissions from road construction and maintenance. This case study will focus on the role of decarbonising road maintenance in the transition to a circular economy.
