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

The ARC Training Centre for Advanced Technologies in Rail Track Infrastructure aims to transform Australia’s rail construction and maintenance technologies through specialist training of industry-focused researchers. Generation of new knowledge and close collaboration with companies within the rail supply chain will result in enhanced rail capacity and supply chain efficiency across the rail network. This will include increased axle loads and higher speeds, greater safety margins, reduced construction and maintenance costs, and a body of competent railway professionals in the nation’s work force.Read moreRead less
Optimisation of shallow geothermal systems for Australian schools. This project aims to increase energy efficiency and reduce greenhouse gas emissions by optimising shallow geothermal systems in Australian schools. Shallow geothermal systems use the ground as a heat source and sink for heating and cooling. Their application to schools has the potential to harness energy from untapped resources such as sport grounds, reduce energy consumption by up to 75% and increase comfort and productivity of ....Optimisation of shallow geothermal systems for Australian schools. This project aims to increase energy efficiency and reduce greenhouse gas emissions by optimising shallow geothermal systems in Australian schools. Shallow geothermal systems use the ground as a heat source and sink for heating and cooling. Their application to schools has the potential to harness energy from untapped resources such as sport grounds, reduce energy consumption by up to 75% and increase comfort and productivity of our children at school. An expected outcome of this project is to create a full scale physical model along advanced optimisation models which will allow better understanding of energy efficiency gains, and lead towards improving geothermal design techniques tailored to educational buildings.Read moreRead less
Paving the way to greener roads and healthier waterways. Waste tyre permeable pavement is emerging as an effective stormwater surge mitigation solution. Yet, its behaviour under traffic loads and varied environmental conditions are not fully understood which undermines industry confidence in this technology. This project aims to advance the engineering of waste tyre permeable pavements by creating new knowledge on their mechanical and hydrological performance. The project will develop design gui ....Paving the way to greener roads and healthier waterways. Waste tyre permeable pavement is emerging as an effective stormwater surge mitigation solution. Yet, its behaviour under traffic loads and varied environmental conditions are not fully understood which undermines industry confidence in this technology. This project aims to advance the engineering of waste tyre permeable pavements by creating new knowledge on their mechanical and hydrological performance. The project will develop design guidelines, identify the governing mechanisms and develop a performance prediction framework based on laboratory and field tests, and advanced numerical modelling. The mechanisms of performance from micro to macro level will be identified, generating knowledge for industry to support widespread uptake.Read moreRead less
A novel quantitative risk assessment framework for fractured rock slopes. Rock slope instabilities present grave risks to life and to the serviceability of major Australian infrastructure such as mines, roads and railways, and to coastal recreation areas. This project aims at developing tools for the quantitative risk assessment of fractured rock slopes based on rigorous rock mechanics, numerical methods and probabilistic methods.
The research outcomes will improve our understanding of natural ....A novel quantitative risk assessment framework for fractured rock slopes. Rock slope instabilities present grave risks to life and to the serviceability of major Australian infrastructure such as mines, roads and railways, and to coastal recreation areas. This project aims at developing tools for the quantitative risk assessment of fractured rock slopes based on rigorous rock mechanics, numerical methods and probabilistic methods.
The research outcomes will improve our understanding of natural and engineering rock slopes, reduce the uncertainties in the prediction of the safety of infrastructures, and thus minimize the loss and damage. The research outcomes can also be used to maintain workplace safety in mining environments and avoid disruptions to production.

Erosion of embankment dams and dam spillways. In excess of $250M is spent annually to maintain, upgrade, improve safety and monitor performance of Australian dams. Improved methods for assessing both spillway and internal erosion, the cause of 50 per cent of embankment dam failures and incidents requiring repairs, will be developed, maximising dam safety and minimising maintenance expenditure.
