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 (such as preservation techniques to service lifetime extension, use of asphalt containing high-recycled content, secondary resources and/or alternative materials) and are used in pavement rehabilitation and maintenance operations.
This work will make it possible to compare and contrast the efficacy of the model developed in WP3 in the context of asphalt pavements. It will also assess the extent to which the application of innovative approaches to asphalt technology brings about circularity in the road infrastructure maintenance sector. Different approaches to CE will be compared in the context of road construction and maintenance.
