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.

Accurate Prediction of Safe Life of Buried Pipelines. Failures of buried pipes are disastrous, causing severe consequences and disruptions. They often reoccur because the fundamental cause-effect relation for pipe failures has not been fully understood and hence the safe life of pipelines cannot be reliably predicted. The aim of this research is to develop a new theory to predict pipe failures, based on a fundamental analysis of pipe behaviour and failure mechanisms and a reliability approach.

They often reoccur because the fundamental cause-effect relation for pipe failures has not been fully understood and hence the safe life of pipelines cannot be reliably predicted. The aim of this research is to develop a new theory to predict pipe failures, based on a fundamental analysis of pipe behaviour and failure mechanisms and a reliability approach. The outcomes will be a suite of models and solutions that will advance knowledge in deterioration science and failure theory. They will provide a sustainable solution to the intelligent management of buried pipelines throughout the world.Read moreRead less

This project aims to develop a technique to accurately predict the remaining safe life of deteriorated buried stormwater pipelines, thereby preventing their catastrophic failure. The research also aims to advance knowledge in deterioration science of reinforced concrete and failure theory of buried pipes. The outcomes are anticipated to be a suite of rational, practical and validated models for pipe deterioration as measured by crack growth and residual strength which are integrated in a time-dependent reliability method and coded as a computer program ready for take-up by end-users. Preventing catastrophic failures of buried pipes should deliver economic, environmental and social benefits.Read moreRead less

The development of knowledge of HCTCRB, an advanced material in the pavement engineering discipline, will underpin growth in the highway and road construction industry. The key outcomes of this study will enhance and change highway and road organisations, contractors, engineers and others interested in the use and design of pavement materials. This is particularly so in light of the recent change to a new era of analytical approaches, rather than the empirical approach of the past. When the outcomes of this project are applied, they will result in an improvement in overall road and highway quality. Read moreRead less

This project aims to use advanced image analysis and cloud computing technologies to replace manual, time-consuming and subjective geotechnical engineering practices with a rapid, automated, and more rational approach. A new geo-materials testing system based on the existing triaxial apparatus will be developed that employs three-dimensional image capture hardware and advanced image analysis techniques. The data measured over the entire sample surface will feed into an automated, intelligent parameter selection procedure combining finite element analysis with numerical optimisation techniques. Application of the proposal’s findings will allow more accurate and efficient engineering design of transport and energy infrastructure that supports modern economies.Read moreRead less
Effect of geopolymer cement stabilisation on the fatigue life of pavement sub-bases with recycled demolition aggregates. Road sub-base construction with demolition wastes using geopolymer stabilisation will be researched as Australian stockpiles of demolition wastes, such as concrete and bricks, are growing at 15 million tons per annum. Current sub-base design methods are intended for virgin materials, hence new research is required for waste materials in sub-bases.
Measuring and modelling the mechanical response of soils incorporating recycled tyres. Civil engineers use backfill to refill excavated areas around new structures. They have found recently that rubber chips and shredded rubber make excellent backfill when combined with a small percentage of cement to make ‘rubber soil’. The widespread use of rubber soil therefore offers a tremendous opportunity to make use of a serious waste product to achieve important engineering outcomes. However, too little ....Measuring and modelling the mechanical response of soils incorporating recycled tyres. Civil engineers use backfill to refill excavated areas around new structures. They have found recently that rubber chips and shredded rubber make excellent backfill when combined with a small percentage of cement to make ‘rubber soil’. The widespread use of rubber soil therefore offers a tremendous opportunity to make use of a serious waste product to achieve important engineering outcomes. However, too little is known about the technology. This project will model the behaviour of rubber soil in order to introduce it as an environmentally sustainable, cost-effective and technically sound choice of geomaterial for both standard and non-standard geotechnical structures.Read moreRead less

Land reclamation is a multi-billion dollar industry that is most often carried out in coastal regions by reclaiming seabed foundations of marine clay using dredged waste. This project will develop an analytical framework for predicting the rate of settlements in the resulting multi-layer system which will incorporate a variety of factors known to directly influence the rate of consolidation. After validation using experimental data and numerical simulations, the proposed analytical model can be used to mimic soil behaviour more closely than traditional models, thereby leading to more realistic settlement predictions.Read moreRead less
