Greek compaction

摘要

Caterpillar soil compactor using the new machine-integrated soil compaction measurement technology Machine Drive Power (MDP) is said to have drastically reduced the number of passes needed on a dam jobsite near Triantafullia in northern Greece. Tena, one of the largest construction companies in northern Greece, was responsible for placing 42m of compacted materials on an existing embankment of 33m. The earthmoving volume for the massive earthen dam exceeded 350,000m3. The material had to be applied in 200mm layers, and compacted to 150mm-at a length of 364m and a width of 18m. Volume was only part of the challenge. George Nathanailidis, president and chief executive officer of Tena, said that because the work was in sandy clay, achieving uniform compaction would have proved difficult, while monitoring densities would be challenging and less than comprehensive.
