Structural Pavement Rehabilitation with Recycled Materials in a Circular Economy Approach

The construction sector accounts for about 34% of the total waste produced in the European Union (EU), with the transportation infrastructure sector, namely the road construction, having a huge impact on waste generation. Asphalt pavements stand for more than 80% of EU’s road network with about 950 billion tons of asphalt being used. A great investment is made every year in maintenance and rehabilitation (M&R) with a view to maintain the minimum levels of service. Being aware that pavement materials are non-renewable resources, it is urgent to ensure cost-effective M&R solutions that promote the transition to new economic models. The overall increase in the use of recycled materials is a main goal for achieving a better efficiency in the technical, economic and environmental management of pavement materials, by making it possible to preserve natural resources for the generations to come and to reduce waste disposal. This approach aims to promote a circular economy, as opposed to a linear economy, by changing the material consumption pattern. The main objectives of this paper are to analyze and compare approaches regarding the different methodologies proposed for structural pavement rehabilitation with recycled materials, by considering the implementation of recycling processes in M&R activities during the asphalt pavement life cycle. The potential application of rehabilitation methodologies using recycled materials will be assessed in terms of production quantities and costs, in comparison with traditional M&R solutions using primary raw materials.
