Abstract
As well known, since the early years of the 20th century, the arbitrary use of metals, irreversibly damaged most of the monuments belonging to the Ancient Mediterraneum historical and archaeological heritage. In fact, several archaeological sites in the southern of Italy and in Sicily are actually passing an arduous phase of de-restoration, dictated from the necessity to remove all these ineffective and obsolete interventions, which have, over time, further damaged monuments, altering their originally static functioning. Studies about anastylosis in Italy are rather delayed, in the face of the important results obtained by researches treated in Greece by highly qualified institutions like the YSMA (The Acropolis Restoration Service) which bore witness of the thirtyyears restoration experience of the Athens ’Acropolis. Since 2010, DICAR's research has tested anastylosis and its problems, thanks to the collaboration of specialized companies, including Pi.Mar, a leading company in Puglia in the production of stone, which was a partner of this experimentation which aims to reproduce elements architectural elaborated thanks to Cad / Cam, a computer assisted technology. The present integrated research develops starting from an experimentation on numerical control prototyping (CAD / CAM) of stone elements for the integration of multiple architectural artefacts: it started in 2010 and is still ongoing, given the collaboration between the Polytechnic of Bari and Pi .mar srl, a leading company in the numerical control prototyping sector. The combined use of innovative systems, such as technical research on the 3D laser system and the CAM / CAD machine based on numerical control, has allowed the optimization of the processing phases. In addition to the definition of a detailed analytical methodology, a contextual finite element analysis (FEA) was planned simultaneously with the pre-primary phase of prototyping, to evaluate the interaction between the components of the original architectural elements and the new additions. The experimentation resulted in a pilot project that led to the anastylosis of the portico of the Roman temple in the park of the Valley of the Temples in Agrigento. The replication of numerous fragments for the compensation of the missing parts with the same original material, the study of the compatible fixing system, have been addressed on a full scale, in order to avoid the alteration of the ancient static system and to guarantee integrity structural element.
