Abstract |
The principles of the circular economy are the basic determinants of the sustainable development of road construction. This paper presents a field study with a new concept of asphalt pavement structure with ecologically oriented attributes, significantly reducing the asphalt pavement carbon footprint while achieving a level of long-term performance comparable or greater than that of conventional pavement structures. The sustainable pavement consists of the introduction of a BIO-additive that allows for the integration of higher percentage of reclaimed asphalt pavement (RAP) as an alternative to the traditional asphalt mixtures. In the sub-base the use of construction and demolition waste was adopted. The results were obtained from a full-sized test section of the road structure divided for reference and eco-innovative cases. Mechanistic analyses were performed for materials and pavement structure based on laboratory tests and on-site assessment. The new eco-design solution was subjected to a comprehensive LCA and LCCA analysis and summarised by SWOT assessment. |
