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

Mitigating the Severity of Level Crossing Accidents and Derailments. Ongoing increases in the number of level crossings and heavy road vehicles cause more frequent and severe level crossing accidents and derailments. Despite the use of active warning systems, each year, on average, 100 level crossing accidents occur in Australia. With a view to mitigating these crashes, this research aims to formulate theories for reduction in crash energy and effective wheel constraints to prevent derailment by ....Mitigating the Severity of Level Crossing Accidents and Derailments. Ongoing increases in the number of level crossings and heavy road vehicles cause more frequent and severe level crossing accidents and derailments. Despite the use of active warning systems, each year, on average, 100 level crossing accidents occur in Australia. With a view to mitigating these crashes, this research aims to formulate theories for reduction in crash energy and effective wheel constraints to prevent derailment by modifying the levels of road and rail crossings and providing guard rails in the recesses of these modified level crossings. The theories are intended be developed using nonlinear dynamic computational methods and laboratory experiments. The outcomes are expected to enable reduction in the severity of level crossing accidents and hence save lives and costs of derailment.Read moreRead less
Multi-functional nano-modified cementitious materials for well cementing. By incorporating different nano-materials in well cements, this project aims to develop multi-functional cementitious materials with self-sensing properties and greater strength and durability under extreme conditions including high/low temperatures, high pressure and corrosive environments. The integrity and longevity of well cement are paramount for the safe, efficient, environmentally sustainable production of oil and n ....Multi-functional nano-modified cementitious materials for well cementing. By incorporating different nano-materials in well cements, this project aims to develop multi-functional cementitious materials with self-sensing properties and greater strength and durability under extreme conditions including high/low temperatures, high pressure and corrosive environments. The integrity and longevity of well cement are paramount for the safe, efficient, environmentally sustainable production of oil and natural gas resources. Cementing problems are the main factor contributing to incidents during drilling and completion of wells, necessitating costly remediation. It is expected that the novel cement developed in the project will produce safer wells with fewer (gas) environmental emission risks.Read moreRead less
Rock Physics: A study of micromechanics of rocks and granulated materials. This proposal will provide an understanding of the micro mechanics of granular materials and of changes at the grain scale when a granular pack undergoes mechanical stress or compaction. Sedimentary rocks, as a natural form of compact granular materials, are abundant in nature and often provide the bed for underground hydrocarbon reserves. This project will answer some of the fundamental questions in petroleum engineering ....Rock Physics: A study of micromechanics of rocks and granulated materials. This proposal will provide an understanding of the micro mechanics of granular materials and of changes at the grain scale when a granular pack undergoes mechanical stress or compaction. Sedimentary rocks, as a natural form of compact granular materials, are abundant in nature and often provide the bed for underground hydrocarbon reserves. This project will answer some of the fundamental questions in petroleum engineering, explaining how and why a sedimentary oil reservoir compacts during oil extraction. The knowledge gained from this project has also important applications in the construction industries and ground water management.Read moreRead less
Global trends in oceanic wind speed and wave height. This project will determine whether winds and waves over the world's oceans have changed over the past 30 years. Such information is critically important in understanding global climate change, evaporation, air-sea interaction and to safely design and operate coastal and offshore facilities.
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.
Reinforced crumbed rubber concrete for residential construction. Reinforced crumbed rubber concrete for residential construction. This project aims to use crumb rubber from used tyres to replace natural sand aggregate in concrete used in housing construction. Globally, very few of the millions of tyres discarded annually are recycled, while natural sand used in concrete is being depleted. This project intends to provide the tyre industry with a viable market for end of life tyres, and the premix ....Reinforced crumbed rubber concrete for residential construction. Reinforced crumbed rubber concrete for residential construction. This project aims to use crumb rubber from used tyres to replace natural sand aggregate in concrete used in housing construction. Globally, very few of the millions of tyres discarded annually are recycled, while natural sand used in concrete is being depleted. This project intends to provide the tyre industry with a viable market for end of life tyres, and the premix concrete industry with a “green” product for the residential construction market. Expected benefits include the increased use of a waste resource (used tyres), reduced use of a scarce natural resource (sand), and the development of an economic but green alternative concrete option for residential builders and owners.Read moreRead less
New Biomimetic Nanostructured Coatings for Hip Implants. Over 30,000 hip implants operations take place in Australia each year, due largely to a significant and growing proportion of the population suffering from conditions such as osteoporosis. The coating on the implants, required to cause good bone ingrowth and adhesion between bone and implant, is far from perfect. We propose to spray coatings which mimic the structure of bone, and thus offer improved mechanical properties such as appropriat ....New Biomimetic Nanostructured Coatings for Hip Implants. Over 30,000 hip implants operations take place in Australia each year, due largely to a significant and growing proportion of the population suffering from conditions such as osteoporosis. The coating on the implants, required to cause good bone ingrowth and adhesion between bone and implant, is far from perfect. We propose to spray coatings which mimic the structure of bone, and thus offer improved mechanical properties such as appropriate rigidity and toughness, and stimulate better bone growth at the interface. In this way the implant should be much longer lasting and the need for undesirable revision surgery reduced. The processing technique proposed could also be a useful platform coating technology in a number of other industries.Read moreRead less
