Abstract
Increasing demand for infrastructures requires innovative, cheap and environmental sustainable practices in construction. The soils which are available on site for linear embankments often need to be improved to satisfy the necessary performance and strength requirements. A bio-improvement is evaluated here, for use in compacted earth construction. To the aim of sustainability and cost reduction, a soft technique was chosen by the industrial party, which consisted in adding bacteria to a superfi...
