Geothermal pavements: field observations, numerical modelling and long-term performance

Date: 09-2022
Abstract: Geothermal pavement systems are a novel type of energy geostructure. They use sub-surface structures to exchange heat with the ground and, thereby, provide thermal energy in addition to structural support. The thermo-activation of pavements has been largely overlooked in the literature. This research focuses on the development of a detailed three-dimensional (3D) finite-element (FE) model to explore the thermal performance of geothermal pavement systems. The 3D FE model developed was successfully validated with both data measured from a full-scale experiment undertaken in Adelaide, South Australia and other published data. The validated model is further employed to evaluate the long-term performance of a geothermal pavement system under both a traditional system configuration and a hybrid system. Furthermore, a life-cycle cost analysis is performed to explore the cost implication of such pavement systems. Results show that a geothermal pavement with total pipe length of 640 m, or a hybrid system (a geothermal pavement system with a pipe length of 320 m and an auxiliary system) can provide for sufficient space heating and cooling for a typical residential building in Australia. It is found that, compared with conventional heating and cooling systems, the geothermal pavement system is indeed a cost-effective solution. This research study indicates that this pavement technology can be successfully implemented in the field and accurately modelled using FE techniques.

DOI: 10.3390/SU13052463
Abstract: This research investigates the static and cyclic characteristics of recycled glass (RG) as a supplementary material with recycled concrete aggregate (RCA) in the rail track capping layer. RG was blended by-weight with RCA in 10% increments up to 50% RG content. A performance-based laboratory testing scheme was designed according to the field loading conditions of capping layers in rail tracks. Basic geotechnical properties of RG + RCA blends were evaluated through their particle size distribution, compaction properties, and California bearing ratio. Effect of flooding was assessed with one-dimensional static and cyclic compression tests. Multistage triaxial compression tests were performed to determine the effect of RG content on shear strength parameters. A new repeated loading triaxial testing protocol was introduced for railway capping layer materials to assess the stiffness of RG blends to cyclic loading. Long term performance of s les also was evaluated through multistage cyclic permanent deformation tests. The shakedown concept was used to assess the permanent deformation results of RG + RCA s les. Results indicated that RG can be used effectively as a supplementary geomaterial in construction of rail track substructure.
Nanoparticles in construction materials and other applications, and implications of nanoparticle use

DOI: 10.3390/MA12193052
Abstract: Nanoparticles are defined as ultrafine particles sized between 1 and 100 nanometres in diameter. In recent decades, there has been wide scientific research on the various uses of nanoparticles in construction, electronics, manufacturing, cosmetics, and medicine. The advantages of using nanoparticles in construction are immense, promising extraordinary physical and chemical properties for modified construction materials. Among the many different types of nanoparticles, titanium dioxide, carbon nanotubes, silica, copper, clay, and aluminium oxide are the most widely used nanoparticles in the construction sector. The promise of nanoparticles as observed in construction is reflected in other adoptive industries, driving the growth in demand and production quantity at an exorbitant rate. The objective of this study was to analyse the use of nanoparticles within the construction industry to exemplify the benefits of nanoparticle applications and to address the short-term and long-term effects of nanoparticles on the environment and human health within the microcosm of industry so that the findings may be generalised. The benefits of nanoparticle utilisation are demonstrated through specific applications in common materials, particularly in normal concrete, asphalt concrete, bricks, timber, and steel. In addition, the paper addresses the potential benefits and safety barriers for using nanomaterials, with consideration given to key areas of knowledge associated with exposure to nanoparticles that may have implications for health and environmental safety. The field of nanotechnology is considered rather young compared to established industries, thus limiting the time for research and risk analysis. Nevertheless, it is pertinent that research and regulation precede the widespread adoption of potentially harmful particles to mitigate undue risk.

Abstract: The select chemical and engineering characteristics of biosolids produced at a wastewater treatment plant in Eastern Australia were investigated to assess its suitability as structural fill material in road embankments. Results of comprehensive set of geotechnical experimentation including compaction, consolidation, creep, hydraulic conductivity and shear strength tests implied that biosolids demonstrate behavior similar to highly organic clays with a higher potential for consolidation and settlement. Results of chemical study including heavy metals, dichloro diphenyl trichloroethane (and derivatives) and organochlorine pesticides, indicate that biosolids s les are within the acceptable limits which allows their usage under certain guidelines. Results of tests on pathogens (bacteria, viruses or parasites) also indicated that biosolids were within the safe acceptable limits. Technical and management suggestions have been provided to minimize the possible environmental risks of using biosolids in road embankment fills.

DOI: 10.1680/WARM.2010.163.1.29
Abstract: Construction and demolition materials account for a major proportion of the waste materials present in landfills in Australia. Crushed brick and crushed rock are, however, viable substitute materials for natural resources used as construction materials in engineering applications. Crushed brick is one of the major components of demolition materials. The crushed rock used in this study originates from ‘basalt floaters’ or surface excavation rock (basalt), which commonly occurs near the surface to the north and west of Melbourne, Australia. The engineering characteristics of various proportions of crushed brick blends with crushed rock obtained from extensive laboratory testing are presented in this paper. The engineering properties obtained were compared with existing local road authority specifications for pavement sub-base or light-duty base material and backfill material for drainage systems to ascertain the potential use of crushed brick blends. The materials for the experimental works were collected from a recycling facility in Victoria, Australia.

Evaluation of interaction properties of uniaxial geogrids with waste foundry sand
Publisher: Thomas Telford Ltd.
Date: 04-2023
Abstract: The reuse of waste materials can help alleviate problems related to placing them in landfill and can also preserve fast dwindling natural granular materials. Waste foundry sand (WFS) can be a promising candidate as a backfill material in the construction of mechanically stabilised earth (MSE) walls. In the design of such MSE structures, the interaction properties between WFS and geogrid reinforcement are important input parameters. In the present study, the interaction properties of a wide range of different polyester (PET) uniaxial geogrids with WFS in two common modes – direct shear and pullout – were evaluated using large-size interface direct shear and pullout tests. In the pullout mode, the interaction of the geogrid embedded in WFS under axial and transverse pullout was studied. The direct shear interface coefficients of four PET geogrids with WFS were found to be in the range observed in conventional fill materials. Higher axial and transverse pullout resistance factors were observed for geogrids with higher tensile strength and higher opening area ratio. Empirical equations were proposed to estimate the axial and transverse pullout resistances of geogrids at two pullout displacements. Finally, sensitivity analyses were carried out to identify the parameters significantly influencing the axial and transverse pullout resistances of geogrids in WFS.

Environmental benefits and recycling options for Wood chips from furniture industries
Publisher: Thomas Telford Ltd.
Date: 05-2017
Abstract: Wood chips are generated from wood industries, particularly from furniture manufacturing. The general reuse options are, however, currently limited to low-value applications. Driven by the adverse impacts of climate change, with the aim of achieving more environmental sustainability through reducing waste and increasing reuse/recycle options, this study investigated the feasibility of using wood chips as a pipe backfilling and embankment fill material. A laboratory assessment undertaken in this research shows that wood chips are suitable as a non-structural embankment fill material, but not as a pipe backfilling material. This research also presents the environmental benefits of using wood chips in natural landscaping and the effects of filter depth in such applications. It is found that wood chips significantly trap total suspended solids (TSS) and total nitrogen (TN), contributing to increased total phosphorus (TP) concentration. As such the use of such material in urban landscaping should be subjective depending on the level of concerns for specific pollutant(s) (TSS, TN and TP). With regard to the effect of filter media depth on pollutants' removal efficiencies, it is found that the pollutants' removal efficiencies linearly vary with filter media depth.

Practical approach to predict the shear strength of fibre-reinforced clay
Publisher: Thomas Telford Ltd.
Date: 02-2018
Abstract: Carpet waste fibres have a higher volume to weight ratio and once discarded into landfills, these fibres occupy a larger volume than other materials of similar weight. This research evaluates the efficiency of two types of carpet waste fibre as sustainable soil reinforcing materials to improve the shear strength of clay. A series of consolidated undrained (CU) triaxial compression tests were carried out to study the shear strength of reinforced clays with 1% to 5% carpet waste fibres. The results indicated that carpet waste fibres significantly improve the effective shear stress ratio and deviator stress of the host soil. Addition of 1%, 3% and 5% carpet fibres could improve the effective shear stress ratio of the unreinforced soil by 17.6%, 53.5% and 70.6%, respectively at an initial effective consolidation stress of 200 kPa. In this study, a nonlinear regression model was developed based on a modified form of the hyperbolic model to predict the relationship between effective shear stress ratio, deviator stress and axial strain of fibre-reinforced soil s les with various fibre contents when subjected to various initial effective consolidation stresses. The proposed model was validated using the published experimental data, with predictions using this model found to be in excellent agreement.

Effect of fiber reinforcement on shear strength and void ratio of soft clay
Publisher: Thomas Telford Ltd.
Date: 08-2018
Abstract: In this study, a series of multi-stage drained reverse direct shear tests were carried out on soft clay s les reinforced with 0.25% and 0.50% polypropylene fibers of 6 mm, 10 mm and 19 mm in length. Tests were carried out at different normal effective stresses and cumulative horizontal shear displacement of 1.17 times of the s le width. Results showed an increase of the shear strength with the increase of fiber content and length. However, the rate of improvement was capped with the normal effective stress applied during the shearing stage. At a high normal effective stress, the shear strength of the fiber-reinforced soft clay approached that of the unreinforced clay regardless of the amount of fiber inclusion. The rate of shear strength improvement decayed with the number of shear cycles. Fiber reinforcement also resulted in a reduction of the compressibility of the soft clay at consecutive consolidation and shear stages. Although the effective internal friction angle of the soft clay was not altered significantly with the fiber reinforcement, the effective cohesion of the soft clay improved significantly as much as 6.4 and 8.5 times with the inclusion of 0.25% and 0.50% of 10 mm long fibers, respectively.

Thermoresponsive Copolymer/SiO2 Nanoparticles with Dual Functions of Thermally Controlled Drug Release and Simultaneous Carrier Decomposition
Publisher: Wiley
Date: 08-08-2014
Abstract: The preparation of thermoresponsive drug carriers with a self-destruction property is presented. These drug carriers were fabricated by incorporation of drug molecules and thermoresponsive copolymer, poly(N-isopropylacrylamide-co-acrylamide), into silica nanoparticles in a one-pot preparation process. The enhanced drug release was primarily attributed to faster molecule diffusion resulting from the particle decomposition triggered by phase transformation of the copolymer upon the temperature change. The decomposition of the drug carriers into small fragments should benefit their fast excretion from the body. In addition, the resulting drug-loaded nanoparticles showed faster drug release in an acidic environment (pH 5) than in a neutral one. The controlled drug release of methylene blue and doxorubicin hydrochloride and the self-decomposition of the drug carriers were successfully characterized by using TEM, UV/Vis spectroscopy, and confocal microscopy. Together with the nontoxicity and excellent biocompatibility of the copolymer/SiO2 composite, the features of controlled drug release and simultaneous carrier self-destruction provided a promising opportunity for designing various novel drug-delivery systems.

Amazing Types, Properties, and Applications of Fibres in Construction Materials
Publisher: MDPI AG
Date: 07-08-2019
DOI: 10.3390/MA12162513
Abstract: Fibres have been used in construction materials for a very long time. Through previous research and investigations, the use of natural and synthetic fibres have shown promising results, as their presence has demonstrated significant benefits in terms of the overall physical and mechanical properties of the composite material. When comparing fibre reinforcement to traditional reinforcement, the ratio of fibre required is significantly less, making fibre reinforcement both energy and economically efficient. More recently, waste fibres have been studied for their potential as reinforcement in construction materials. The build-up of waste materials all around the world is a known issue, as landfill space is limited, and the incineration process requires considerable energy and produces unwanted emissions. The utilisation of waste fibres in construction materials can alleviate these issues and promote environmentally friendly and sustainable solutions that work in the industry. This study reviews the types, properties, and applications of different fibres used in a wide range of materials in the construction industry, including concrete, asphalt concrete, soil, earth materials, blocks and bricks, composites, and other applications.
Impact of suffusion on the cyclic and post-cyclic behaviour of an internally unstable soil
Publisher: Thomas Telford Ltd.
Date: 09-2019
Abstract: Suffusion is defined as the migration of fine particles caused by seepage flow through pre-existing pores of a soil structure made of coarse particles. This particle transportation changes the fine particle content and its distribution, possibly impacting the mechanical behaviour of eroded soil. Although limited research has been conducted on the post-erosion mechanical consequences under monotonic shearing, little attention has been paid to the impact of suffusion on the cyclic resistance and liquefaction potential of internally unstable soils. This paper investigates the cyclic and post-cyclic behaviour of a gap-graded cohesionless soil using combined triaxial-erosion apparatus. An internally unstable soil was chosen for the erosion test and was subjected to different seepage flow velocities and durations followed by cyclic loading and post-cyclic shearing. During cyclic loading, the eroded specimens with different residual fine contents behaved in a similar manner to a soil specimen constructed only of coarse particles. Regardless of the seepage velocity and duration, the erosion of fine particles resulted in significant increase in cyclic resistance. It is understood that eroded specimens with lower intergranular void ratios show higher resistance during cyclic loading, highlighting the importance of the intergranular void ratio in understanding the post-erosion mechanical behaviour of soils.
Comparison of influenza vaccination coverage between immigrant and Australian-born adults

DOI: 10.1016/J.VACCINE.2016.10.012
Abstract: Australia has a large immigrant population but there are few data regarding whether influenza vaccine coverage in adults varies according to country of birth. We quantified and compared self-reported influenza vaccination coverage between Australian-born and immigrant residents aged ⩾49years enrolled in a large cohort (the 45 and Up Study), surveyed in 2012 and 2013. Estimated vaccine coverage was adjusted for age, sex and other factors known to be associated with vaccine uptake. Among 76,040 participants included in the analyses (mean age 66.2years), 21.6% were immigrants. In Australian-born adults aged 49-64 and 65+ years the age- and sex-adjusted estimates for influenza vaccination within the year prior to survey was 39.5% (95% CI 38.9-40.0) and 70.9% (70.4-71.5) respectively. The corresponding estimates in immigrants were significantly lower at 34.8% (33.7-35.8) and 64.4% (63.4-65.4) respectively. Among immigrants, coverage varied by region of birth, and was slightly lower among those who spoke a language other than English at home compared to those who only spoke English. Among immigrants there was no significant difference in coverage comparing those who migrated when they were children to those who migrated as adults and coverage did not differ significantly according to years lived in Australia. Programs to increase adult vaccination coverage should consider the needs of immigrants.

Abstract: Delineation of groundwater vulnerability zones based on a valid groundwater model is crucial towards an accurate design of management strategies. However, limited data often restrain the development of a robust groundwater model. This study presents a methodology to develop groundwater vulnerability zones in a data-scarce area. The Head-Guided Zonation (HGZ) method was applied on the recharge area of Oemau Spring in Rote Island, Indonesia, which is under potential risk of contamination from rapid land use changes. In this method the model domain is ided into zones of piecewise constant into which the values of subsurface properties are assigned in the parameterisation step. Using reverse particle-tracking simulation on the calibrated and validated groundwater model, the simulation results (travel time and pathline trajectory) were combined with the potential groundwater contamination risk from human activities (land use type and current practice) to develop three vulnerability zones. The corresponding preventive management strategies were proposed to protect the spring from contamination and to ensure provision of safe and good quality water from the spring.

Abstract: A comprehensive suite of geotechnical laboratory tests was undertaken on s les of recycled crushed glass produced in Victoria, Australia. Three types of recycled glass sources were tested being coarse, medium and fine sized glass. Laboratory testing results indicated that medium and fine sized recycled glass sources exhibit geotechnical behavior similar to natural aggregates. Coarse recycled glass was however found to be unsuitable for geotechnical engineering applications. Shear strength tests indicate that the fine and medium glass encompass shear strength parameters similar to that of natural sand and gravel mixtures comprising of angular particles. Environmental assessment tests indicated that the material meets the requirements of environmental protection authorities for fill material. The results were used to discuss potential usages of recycled glass as a construction material in geotechnical engineering applications particularly road works.

Evaluating the impact of grid cell properties in spatial discretization of groundwater model for a tropical karst catchment in Rote Island, Indonesia

Abstract: To assess the effect of three grid cell properties (size, mean slope of the surface and distance between centre of grid and observation well) on groundwater models' performances, a tropical karst catchment characterized by monsoonal season in Rote Island, Indonesia was selected. Here, MODFLOW was used to develop models with five different spatial discretization schemes: 10 × 10 m, 20 × 20 m, 30 × 30 m, 40 × 40 m and 50 × 50 m. Using parameter estimation method, hydraulic conductivity and specific yield values over a selection of pilot points were estimated. The trends of the performances were calculated at each observation well in order to recommend the most appropriate location for observation well placement in terms of topographical characteristic. It is confirmed that the deterioration of model performance is mainly controlled by the increase of distance between well and centre of the cell, and the mean slope of the surface. Results reveal that model performance increases substantially for areas of low slope (& %) and medium slope (3–10%) for a smaller grid cell size. Therefore, to improve model performance, it is recommended that the observations wells are placed in areas of low and medium slopes.

Wheel tracker testing of recycled concrete and tyre aggregates in Australia

Abstract: Due to the ever-increasing abundance of discarded by-products, it is imperative to develop innovative engineering applications of waste materials, to manage the capacity of landfills. The disposal and landfilling issues associated with tyre waste have necessitated Australian authorities to find innovative applications of tyre waste in pavement construction. In this research, to examine the efficiency of tyre-derived aggregates (TDAs) as a replacement material for quarry aggregates in pavement subbase applications, a series of repeated load triaxial (RLT) tests and wheel-tracker (WT) tests were undertaken on specimens made of proportioned recycled concrete aggregate (RCA) blended with small-sized TDA (TDA-S) and medium-sized TDA (TDA-M), thus merging these two waste materials into a valued pavement-construction material. The results from the RLT and WT tests confirmed that TDA–RCA blends are a suitable alternative for pavement base/subbase materials. Compared with TDA-S, TDA-M resulted in a lower rutting deformation and permanent deformation in WT and RLT tests, respectively. The resilient modulus (M r ) of the RCA + TDA-M mix was also found to be higher than that of the RCA + TDA-S mix, and it was almost comparable with the M r of the control RCA.
