Session: 48, Room:
The paper focuses on emerging (bio-) chemical techniques used to improve engineering properties of two problematic earthwork materials of the UK rail network to address transport earthwork infrastructure resilience in view of climate change. Studied techniques include novel cementing agents (e.g. alkali-activated cements), and/or soil cementation through calcite precipitation mediated by screened and isolated non-pathogenic indigenous bacteria, enhanced by bioaugmentation and electrokinetic treatment. The proposed treatments were evaluated based on unconfined compressive strength (UCS).
