General principles of assessment and characterization of excavated soil and rocks

PRIU IC: General principles of assessment and characterization of excavated soil and rocks and demolition materials for an economically and environmentally sustainable reuse in the structures and infrastructures of the San Marino territory

The project represents the answer to the need for a radical change in production processes aimed at the construction sector in favor of eco-sustainable techniques and a circular economy in which waste becomes a resource again and actual waste is reduced to a minimum. This process is essential to create a system increasingly oriented towards ecological transition, which aims to safeguard the planet.

Learning outcomes

As part of this project, which brings together skills from various sectors, specific aspects of the San Marino territory will be analysed and evaluated with the aim of optimising the recovery of both demolition materials and excavated earth and rocks and of directing future generations towards a sustainable built environment and starting a system based on the circular economy.

Expected results

The project results will focus on the following aspects:

• Analysis of the territory of the Republic of San Marino from a geolitological and hydrogeological point of view in order to identify the prevalent lithotypes and any environmental characteristics that may influence possible intervention and excavation approaches.
• General analysis of representative lithotypes from a geotechnical and geomechanical point of view.
• Creation of an information tool to define a rough zoning, useful for framing the prevalent types of soils and rocks present in the territory as well as the potential interferences with local hydrogeological structures and to direct the choice of a potential sustainable reuse in a local context.
• Reflections, in light of the main national and international regulations, for the optimization of characterization and assessment investigations of excavated soil and rocks in the Sammarinese territory.
• Identification of geometric and physical tests to be carried out on demolition materials and recovered bituminous conglomerate for recycling in the road sector.
• Identification of modelling techniques used for eco-sustainable materials and development of mathematical analysis methods suitable for treating innovative constituents introduced to improve their behaviour
