Research Expertise
Research expertise is mostly centered around field study and laboratory testing of geomaterials including unsaturated soils, expansive clay soils, silica sands, soft clays and weak sedimentary rocks. This work has extended to include the formulation and development of site condition models for different geological environments and behavioural models for geomaterials. Research has focused more on practical application than on theoretical developments. It is also intentionally cross-disciplinary, aimed at enhancing the state of knowledge in the different disciplines by combining it with what is known from other disciplines. Specific contexts include better prediction models for predicting foundation movements in expansive soils, better characterisation of expansive soils, mechanisms of slope stability related to geological structure, the structure and properties of soft soils in estuarine environments, the geotechnics of minespoil and failure mechanisms of plate anchors in sand.

Teaching Expertise
Teaching expertise includes a wide range of topics within civil and geotechnical engineering. Teaching in Transportation Engineering includes topics such as pavement engineering, pavement materials, geometric design, traffic analysis and traffic control. Teaching in soil mechanics includes soil classification, the fundamentals of stress, pore pressure and permeability, consolidation, laboratory testing and application to practice. Teaching in Geotechnical engineering includes applied design methods such as deep and shallow foundations, pile design, retaining wall design, in situ testing, site investigation and contaminated site assessment. Teaching in Engineering Geology includes basic rock types and description, fundamental geological processes, geological structures, weathering and geological mapping. Teaching in geotechnical engineering involves simulated integrated design exercises across all aspects of the discipline with emphasis on professional practice. Teaching in unsaturated soils involves fundamentals of soil particles and soil structure, soil suction and its measurement and basic unsaturated soil behaviour.

Administrative Expertise
Currently: Director of NUsport (Newcastle University Sport), Civil Engineering Program Convenor, Committee member of Newcastle Chapter of the Australian Geomechanics Society. Formerly: representative on Academic Senate and Deputy President, Head od Discipline (Civil, Surveying and Engvironmental Engineering), member of the University of Newcastle Industry Scholarship Scheme (UNISS) Executive group, coordinator of UNISS scholarships in Civil Engineering, formal liaison with Civil Engineering laboratory staff, participant in the Science and Engineering Challenge.

This paper documents a rock fall in the Hawkesbury Sandstone. Two distinct phases, preceding the ultimate rock fall event have been identified and documented; a creep-loading phase and a rock fracture phase. Water is identified as playing a significant role in the creep-loading phase. Over the long term, peak water pressures from intermittent heavy rainfall events have contributed to the slow, creeping movement of the overlying, joint-bounded block resulting in the progressive loading of the underlying rock mass. The rock fracture phase was extremely rapid and overlaps with the rock fall event. The kinematics of the rock fall has been interpreted from broken surfaces, scratches and positions of debris. From the timing of events, it is likely that wetting/saturation of the intact sandstone from sustained rainfall in the weeks preceding the rock fall would have significantly reduced the intact rock strength. Based on the site investigation and reconstruction of the failure mechanism, the rock fall is classified, in the Crunden and Varnes (1996) scheme, as a complex extremely rapid rock fall and rapid dry debris slide.

From a consideration of the concepts of geological weathering and structure, it can be expected that rockfall hazards should be characteristically different in different geological environments. This paper tests this idea by looking at the geometric characteristics of rock fragments formed on natural slopes in four different geological environments in Eastern Australia, where rockfall phenomena are often characterised by rolling of pre-detached debris. By measuring the three principle dimensions and making a systematic assessment of the shape characteristics of samples of rock debris in significant geological environments, it is found that the distributions of size and shape for the surface debris are statistically different. From the results, it is shown that the size and shape of debris is directly controlled by the rock type, its weathering characteristics and the structure of the parent rock mass. The severity of rockfall hazards is shown to be relatively lower in areas of Tertiary basalt, as the size of rolling fragments is limited by closely spaced fracturing inherited from its formation and the tendency to deteriorate further as it weathers deeply and rapidly. It is also lower in areas of Palaeozoic volcanics, since these tend to produce relatively angular fragments with higher proportions of fragments that are inherently more resistant to rolling. By contrast, thickly bedded sandstones form larger blocks with a larger proportion of shapes that are more prone to rolling. The size distribution of fragments is shown to be well approximated by a log-normal statistical distribution, and using the data provided in this study, it is possible to generate the size and shape data needed to undertake a stochastic assessment of rockfall trajectories in different geological environments. © 2013.

This work reveals an interesting feature of sand behaviour: the ratio of the minimum and the maximum dry density, D, is about constant. This statement is discussed here on the basis of the analysis of two databases: the database of the "Calibration Chamber" sands and the database of the Danube sands. Results show that although the D values are significantly and systematically different for the Calibration Chamber sands and the Danube sands, the coefficients of variation of the D values for each sample population is very small in each case. The difference in the characteristic D values in each case is explained in terms of differences in the experimental methods used and differences in the geological origin of the soils.

This paper presents a case study to illustrate the role played by geologic structures in the design and construction of major transportation infrastructure, in a setting of moderately deformed Paleozoic sedimentary rocks in eastern Australia. It describes a complex development of folding, faulting and jointing that has resulted in significant inclination of beds, juxtaposition of strata and affected the weathering characteristics of a wide range of rock types. The sequence, which displays an upward transition from marine to terrestrial sediments, comprises an interbedded succession of conglomerate, sandstone, shale and erratic volcanics and crystal tuff. Unfavorable relationships between major excavation faces, inclined beds and jointing have resulted in problems with the stability of road cuttings. Also, the presence of faults and dykes at various scales has had a significant effect on weathering and rock strength. The paper demonstrates the importance of the choice of alignment at design stage, and how a basis of good structural interpretation and geologic mapping can be used to avoid problems during construction and issues with ongoing maintenance. © 2007 Akadémiai Kiadó.

The grading entropy of a soil [S] is derived in terms of the more general concept of statistical entropy. It consists of two terms: the base entropy [So], arising from the difference in the width of the statistical cells in the conventional grading curve, and the entropy increment [¿S]. The goal of the research is to study which grading entropy plays the role of the "true" entropy in a thermodynamic sense (i.e. undergoes an increase during the crushing process being considered as an irreversible thermodynamic process): the entropy increment [¿S] or the sum of the base entropy and the entropy increment [S]. The soil samples are subjected to some crushing tests and direct shear test. The grading curve and the grading entropy are determined before and after each test. It is found that only the entropy increment [¿S] increases in the tests.

This paper investigates the factors affecting the shear strength of granular materials by means of the tilt box test. The test involves the titling of a specifically designed split-box and measuring the angle at which the upper half of the box slides off. This angle can be interpreted as the peak friction angle of the sample for a low stress state. Experimental tests and numerical analyses using the Discrete Element Method (DEM) are carried out and compared. The study is carried out for two different materials, a rounded and an angular aggregate. It is shown that rolling resistance is needed to match the experimental results if only spheres are used but this is not the case for non-spherical particles. © 2015 Taylor & Francis Group, London.

The solution of non-linear inverse problems and the reliability testing of the solution may be impeded by noise in the data. Three methods are presented for addressing these problems. The first method recognizes that some parameters can be eliminated from the solution through sub-minimization. In the second method - To "clean" the merit-function - The concept of the closest noise-free merit-function ('follower') is introduced, which can be approximated by the real-life merit-function on a part of the parameter domain, on the condition that the shape of the noise-free merit-function is 'model invariant' being known a priori. In the third method the first method is used and it is shown that if all parameters are eliminated except one, then the transformed merit-function (depending on only one parameter) can be used for reliability testing. The complementary methods are illustrated by the example of the modification of the shark secant method and by the evaluation of a basic geotechnical test. © 2015 Taylor & Francis Group, London.

The Hunter Expressway is a $1.7 billion road project in the Hunter Valley, NSW, Australia to provide a new east-west connection between Newcastle and the Lower Hunter. A large part of the materials encountered on site are expansive tuffaceous soils that would normally be discarded. However, because of increasing financial, environmental and space constraints, it is required to make use of these swelling materials in embankments. These materials include highly weathered claystone containing about 20% in mass of smectite. The highly plastic claystone is present in layers alternating with layers of nonplastic coal. Hence, when excavating the material, the claystone is mixed with the coal and it becomes relevant to consider the swelling potential of the mixture instead of that of the claystone alone. Some typical coal and claystone materials used in embankments were characterized by compaction curves and Atterburg limits. Then, a series of swelling tests were conducted on compacted specimens, of mixtures of coal and claystone, prepared in the laboratory with comparable initial conditions (suction and void ratio) so that any change in swelling potential could be solely attributed to the coal content. The results show that the addition of the coal has an effect in reducing the swelling potential of the claystone beyond a simple dilution effect. Some type of swell inhibition is implied. The addition of coal also significantly reduces the time taken for final swell strain to be reached. © 2014 Taylor & Francis Group, London.

In Australia there has been a significant increase in areas affected by dryland salinity over the 200 years since European settlement. As a result of land use and climatic changes this trend is expected to continue, with areas at high risk of dryland salinity predicted to more than double over the next 40 years. This presents a significant risk to road asset managers as concentration of salts within road pavements has been shown to cause damage to pavements and surfacings. The present study explores the impact of dryland salinity on road pavements by assessing the effect of naturally occurring salts on the tensile and shear strength of a sealed granular pavement. Tensile and shear strength testing was conducted on a granular pavement material at a range of salt concentrations. This testing confirmed that the presence of natural salts can have a positive effect on bitumen-sealed granular pavements in contrast to the negative impact salt crystallisation can have on bitumen surfacings. While in solution, salts were found to have a very small positive effect on tensile and shear strength, which is likely related to clay chemistry interactions. Upon crystallisation, salts were observed to form cubic bonds within the pores of the granular material which led to a significant increase in tensile strength. However, at interface between the surfacing and the granular material whisker-shaped crystals were observed to grow from the bitumen. The results suggest that increases in dryland salinity, while presenting a risk to the performance of road surfacings, may actually increase the tensile and shear strength of road pavement materials.

This paper presents the results from an extensive parametric sensitivity analysis of coupled consolidation and solute transport in composite landfill liner systems. Analyses investigate various model parameters including waste loading rate, initial void ratio, compression index, hydraulic conductivity and thickness of the clay liner. Identification of dimensionless quantities characterizing transport and consolidation behaviour allows representation and comparison of a large amount of numerical data in compact form. Utilizing this approach, we could identify the key determinants governing contaminant transport through liner systems. Numerical results reveal that in cases of high liner compressibility, an order of magnitude reduction in contaminant transit time relative to a diffusion analysis may arise due to coupling between solute transport and consolidation. The results suggest that use of coupled consolidation-contaminant transport model is required for conservative design of engineered landfill liner systems. Copyright ASCE 2008.
