Development of advanced deterioration model for the design of stabilised pavement bases. The Australian road network is a lifeline infrastructure that underpins the nation's living standards and economy. Much of these roads have deteriorated and require rehabilitation to get a new lease of life. This project intends to develop advanced methods to extend the lives of these pavements using in-situ recycling of old pavement materials.

This project aims to develop an innovative composite panel system using aerated geopolymer and a thin high strength steel casing. The new panel system aims to have a number of significant enhancements compared to traditional panels in terms of load resistance, much lower carbon footprint and life-cycle costs. It aims to offer desirable properties, such as being light-weight, easy to construct, economical, recyclable and reusable. A significant gap in knowledge exists in the material and system behaviour of the aerated geopolymer and its fire performance. It is intended that a comprehensive research program will be carried out to address those challenges and to provide design guidelines to rapidly progress these technologies in Australia and overseas.Read moreRead less
Development of next generation fire-resistant composite columns. This project aims to develop a new generation of concrete-filled steel tubular (CFST) columns free from reinforcement by using fly ash-based fire-resistant concrete. In Australia, existing CFST columns use a large amount of internal reinforcement to maintain the structural integrity under fire attack. Through the generation of CFST columns with superior fire resistance rating and associated design rules to enable innovative and saf ....Development of next generation fire-resistant composite columns. This project aims to develop a new generation of concrete-filled steel tubular (CFST) columns free from reinforcement by using fly ash-based fire-resistant concrete. In Australia, existing CFST columns use a large amount of internal reinforcement to maintain the structural integrity under fire attack. Through the generation of CFST columns with superior fire resistance rating and associated design rules to enable innovative and safe applications of these columns in the construction of resilient and sustainable infrastructure, the project will enable expansion of the domestic and worldwide market for Australian producers of geo-polymer concrete and fly ash aggregates.Read moreRead less
Understanding mud pumping in heavy haul railroads. This project aims to examine the factors that cause mud pumping and evaluate the effectiveness of sub-surface drainage to prevent rail track instability. Fast heavy haul operations (such as loads used in mining and agriculture) impart repeated loads on the natural formation that can result in mud pumping. If the build-up of water pressure becomes excessive this can cause track failure. Through an experimental program and field study, the mechani ....Understanding mud pumping in heavy haul railroads. This project aims to examine the factors that cause mud pumping and evaluate the effectiveness of sub-surface drainage to prevent rail track instability. Fast heavy haul operations (such as loads used in mining and agriculture) impart repeated loads on the natural formation that can result in mud pumping. If the build-up of water pressure becomes excessive this can cause track failure. Through an experimental program and field study, the mechanisms of mud pumping, incorporating train loads and frequencies, will be studied, and the role of vertically installed drains will be quantified for improved practical design. The project aims to contribute to improved track longevity and reduced maintenance costs, with a corresponding boost in rail productivity.Read moreRead less

This project aims to address durability and sustainability issues with traditional lime-based methods used to stabilize expansive soils by alternatively advancing an alkali-activation approach. It expects to generate new knowledge in using alkali-activation to suppress the swelling potential of expansive soils which have been deleterious to roads, pavements and overlying structures. Expected outcomes of this project include development of a long-term durable treatment with reduced carbon footprint and use of waste materials. This should provide significant benefits commercially and critical insights to overcome expansive soils which cover approximately one-fifth of Australia’s surface area and six out of eight of its largest cities.Read moreRead less
Geotechnical properties and compaction characteristics of granular wastes as potential port reclamation fill. In moving towards sustainable waste management, the Australian mining and steel industry is proactively seeking large scale recycling schemes for coal wash and slag.

In moving towards sustainable waste management, the Australian mining and steel industry is proactively seeking large scale recycling schemes for coal wash and slag. If the construction potential of these wastes is favourable for reclamation, then the environmental and socio-economic benefits will be substantial due to less quarrying of fresh rock and reduced volume of waste tips on otherwise usable land. The research outcomes will be published in peer-reviewed journals and conferences, raising Australia's scientific profile in granular waste management. The geotechnical community will benefit through the rigorous training of professionals, while industry hosted seminars will promote the dissemination of knowledge gained to practitioners.Read moreRead less
