Abstract

In the civil engineering sector and in particular in road construction, attention is increasingly being focused on the need for "sustainable development", which reflects the growing trend, on the one hand, to reduce the amount of materials taken to landfills and, on the other hand, to conserve and reuse non-renewable resources (suitably treated) instead of raw materials that should be preserved in nature. The aim of this thesis was to enhance the conservation of local natural resources by reusing secondary raw materials such as Reclaimed Asphalt Pavement (RAP), Jet grouting waste (JW) and plastic waste (PW) in the construction of sustainable infrastructures. The different sizes of each material have led to investigate the mechanical behaviour of different scales of the mixture; in particular, laboratory tests have focused on the rheological behaviour of bituminous mastics when JW and PW are adopted as filler, while static and dynamic tests focused on hot and cold bituminous mixtures when JW and RAP are used as aggregates. With the aim to create a complete procedure supporting the decision makers in the comparative analysis of the designed bituminous mixtures as base layer of a flexible pavement, taking into account not only the mechanical variables linked to the performance of the mixtures, but also in terms of environmental sustainability, an LCA was developed. Finally, to identify the most appropriate bituminous mixture solution, a sensitivity analysis was implemented.
