Project Description

Graphical representation of PI, LL estimates of resulting soil mixtures

Project DescriptionEarthworks aggregate excavation volume 2,000,000m3 andembankment fills volume 1,700,000m3 (out of which animportant portion consists of upgrading the existing alignmentthrough lateral extension to a four lanes motorway)Embankments mainly low in heightMax. embankment height: 8m

Geology Trial embankment (H=8m) cross sectionAlignment crossing plains featured with alluvial deposits(consisting of clays, silts and sands and mixtures) and hills ofweathered peridotites

Our Services• Evaluation of available laboratory tests on the parent

(“unsuitable”) soil materials for embankment’s fill use• Evaluation of available laboratory tests on the potential

“borrow” materials for embankment’s fill use

Trial embankment (H 8m) cross section

borrow materials for embankment s fill use• Substantiated design, for mechanical mixing of the

“unsuitable” materials of the project with the “borrow”materials (mixing proportions, laboratory tests, field trials etc.)

• Substantiated design for the construction of two (2) testembankments and monitoring instrumentation program

• Interpretation of the monitoring results of the two testembankments
