A micro- and macro-scale investigation of the geotechnical properties of a pyroclastic flow deposit of the Colli Albani

© 2016 Taylor & Francis Group, London. The paper presents the results of a recent investigation of the geotechnical properties of a pyroclastic flow deposit of the Colli Albani volcanic complex, locally known as Pozzolanelle. The investigation focused on the micro-structural features of the material, as observed in thin sections and SEM micrographs, on its physical and mechanical properties at the scale of the laboratory sample, and on its macro-structural features at the scale of the in situ deposit.
