New procedures and materials for improving protection of archaeological areas (original) (raw)

This paper explains the role of nondestructive testing (NDT) in the protection of archaeological sites, as well as research activity and a pilot project in Sardinia, an island region of Italy. Microclimate, surface temperature and sun irradiation, as well as wind direction and speed were monitored for two years by means of infrared thermography, psychrometry and probes to determine requirements for a new shelter. In addition, several technical aspects were analyzed, highlighting how traditional covering solutions can often contribute to damage instead of offering protection. To overcome the limits of typical protective building systems, the project for new shelters needed to combine the requirements for preservation (compatibility and reversibility of new materials, as well as protection from environmental aggression) and new issues for use (flexibility, feasibility, lowest maintenance and easy deconstruction to allow reuse of the shelter in different locations and/or seasons).
