Calibration of the comprimeter for compaction control


Saint-Gobain Weber Portugal, S.A. and the National Laboratory for Civil Engineering (Laboratório Nacional de Engenharia Civil – LNEC) in cooperation with the Instituto Superior Técnico (IST), signed a protocol, in 18th of March of 2010, aiming the study of a control method of the construction of embankments with light expanded clay aggregates. A set of checking and calibration tests, at the laboratory, using the comprimeter, was defined for the evaluation of the compaction conditions of theses materials. This document presents the preparations conditions, the results and interpretation of the tests after the conclusion of the experimental program at the laboratory.
