Three existing landfills for wastes from Carter Holt Harvey Pulp & Paper, Tasman have or are reaching the end of their lives. These landfills receive primary solids (boiler fly-ash, wood fibre and lime mud – dewatered to 25-30%), secondary solids (slurry of dewatered dredgings from wastewater treatment plant…
Biosolids are a mixture of water and organic material, which are a by-product from domestic and industrial sewage treatment processes. Biosolids for this research were obtained from a wastewater treatment plant located in west of Melbourne, Australia. As part of this research, an extensive suite of geotechnical tests…
In Australia, over 300,000 dry tonnes of biosolids are produced and millions of dollars expended for their management annually. Biosolids are the end product and the main solid component collected from the wastewater treatment process. In this study, some of the geotechnical properties of two biosolids samples from…
Field inspection of steep slopes adjacent to transport corridors can pose serious safety hazards. An accident that occurred on one such project highlights the risks and safety considerations posed for geotechnical fieldwork. Geomorphic evaluation of slopes was undertaken in the Waioeka Gorge to assess the risk to the…
Explorations of the ground for geotechnical purposes entail a risk of striking buried services. Without mitigation the risk of striking a buried service is greater especially in urban areas where the number of buried services is increasing plus a larger proportion of exploration is undertaken and value…
Sydney Ports Corporation completed in 2013 the construction of the new Bulk Liquids Berth (BLB2) at Port Botany, NSW. (The BLB2 LP was transferred to NSW Ports on 1 June 2013 as part of the 99 year lease for Port Botany and Port Kembla). The berth construction…
Geotechnical engineering is an experience-driven discipline. Field observations are particularly important because it is difficult to replicate in the laboratory the characteristics and response of soil deposits built by nature over thousands of years. Furthermore, much of the data generated by a major disaster is…
