Anisotropic behaviour of natural soft soils. This project aims to improve current engineering analysis methods, which often fail to predict the performance of infrastructure built on natural soft soils. This project expects to develop a theoretical and mathematical framework to describe the response of soft soils to complex loading patterns imposed by transport and energy infrastructure. This will be informed by advanced laboratory experiments that transcend the capabilities of routine testing m ....Anisotropic behaviour of natural soft soils. This project aims to improve current engineering analysis methods, which often fail to predict the performance of infrastructure built on natural soft soils. This project expects to develop a theoretical and mathematical framework to describe the response of soft soils to complex loading patterns imposed by transport and energy infrastructure. This will be informed by advanced laboratory experiments that transcend the capabilities of routine testing methods. The expected outcome of the project is a series of tools for the engineering analysis of earthworks and foundations built on soft soils that will underpin the construction of civil infrastructure on ground often too poor to be considered for other use.Read moreRead less
A novel design approach for sustainable and resilient railway formations. The project aims to validate a novel design approach for more sustainable and resilient railway formations. The railway network underpins the Australian economy and its maintenance costs tens of millions of dollars every year. This cost will increase with the growing frequency and intensity of climatic events. The research will advance the knowledge on the effect of water on the performance of railway formations and will d ....A novel design approach for sustainable and resilient railway formations. The project aims to validate a novel design approach for more sustainable and resilient railway formations. The railway network underpins the Australian economy and its maintenance costs tens of millions of dollars every year. This cost will increase with the growing frequency and intensity of climatic events. The research will advance the knowledge on the effect of water on the performance of railway formations and will deliver a novel design tool for end-users that will allow engineers to recycle fouled ballast in formations . The project will yield significant financial benefits for Australia, will strengthen links between Academia and industry partners, and will address environmental and sustainability issues linked to fouled ballast.

Hybrid Pile-Drain System to Stabilise Railways Built on Soft Soils. Australian coastal soils often pose significant challenges in the design and construction of railways. The project aims to develop a novel hybrid system of pipe piles & prefabricated vertical drains installed to prevent soft foundation soil (subgrade) from excessive yielding under prolonged cyclic loading by heavy-haul trains. Using large-scale physical model simulations and field trials supported by numerical analysis of soil-p ....Hybrid Pile-Drain System to Stabilise Railways Built on Soft Soils. Australian coastal soils often pose significant challenges in the design and construction of railways. The project aims to develop a novel hybrid system of pipe piles & prefabricated vertical drains installed to prevent soft foundation soil (subgrade) from excessive yielding under prolonged cyclic loading by heavy-haul trains. Using large-scale physical model simulations and field trials supported by numerical analysis of soil-pile-drain interaction mechanisms, this innovative concept will be examined to establish a user-friendly design methodology. For rail operators, the outcomes will generate substantially reduced maintenance costs, while extending the longevity of track infrastructure to ensure faster and heavier trains of the future.

Novel test and design methods for base course reinforced flexible pavements. This project aims to develop the mechanics of geosynthetic-reinforced flexible pavements as an urgent need for the Australian pavement industry to build more sustainable and economical roads. Novel laboratory test apparatus and in-situ test programs, and mathematical models will be developed, for the first time, to capture the responses of reinforced base courses in a complete and optimised way to determine the paramete ....Novel test and design methods for base course reinforced flexible pavements. This project aims to develop the mechanics of geosynthetic-reinforced flexible pavements as an urgent need for the Australian pavement industry to build more sustainable and economical roads. Novel laboratory test apparatus and in-situ test programs, and mathematical models will be developed, for the first time, to capture the responses of reinforced base courses in a complete and optimised way to determine the parameters for pavement design and performance evaluation. The outcomes will enable reliable prediction of reinforced pavement behaviour, leading to better-performing geosynthetic products and more resilient pavements, reduced material usage and damage in pavements, and less environmental impact and maintenance cost.Read moreRead less

Summary
Stabilising soil foundation with biopolymer for enhanced rail transport. This project aims to develop a novel cost-effective and eco-friendly method to stabilise soil foundation for faster and heavier rail transport. The scientific knowledge of cyclic behaviour capturing localised and microscale evolutions of railway foundation will be advanced significantly via innovative physical modelling using iconic facilities with state-of-the-art sensors, and sophisticated numerical modelling.

This project aims to develop a novel cost-effective and eco-friendly method to stabilise soil foundation for faster and heavier rail transport. The scientific knowledge of cyclic behaviour capturing localised and microscale evolutions of railway foundation will be advanced significantly via innovative physical modelling using iconic facilities with state-of-the-art sensors, and sophisticated numerical modelling. The project will yield a natural biopolymer-based solution for mud pumping railways, i.e., a critical issue causing substantial annual maintenance cost and poor transport efficiency in Australia and worldwide. The outcomes will greatly benefit transport infrastructure, mining, agriculture, environment and climate change remediation.Read moreRead less
