Recovery and Restructuring of Fine and Coarse Soil Fractions as Earthen Construction Materials

Excessive consumption of natural resources to meet the growing demands of building and infrastructure projects has put enormous stress on these resources. On the other hand, a significant quantity of soil is excavated for development activities across the globe and is usually treated as waste material. This study explores the potential of excavated soils in the Brittany region of France for its reuse as earthen construction materials. Characterization of soil recovered from building sites was carried out to classify the soils and observe their suitability for earthen construction materials. These characteristics include mainly Atterberg limits, granulometry, organic matter and optimum moisture content. Soil samples were separated into fine and coarse particles through wet sieving. The percentage of fines (particles smaller than 0.063 mm) in studied soil samples range from 28% to 65%. The methylene blue value (MBV) for Lorient, Bruz and Polama soils is 1, 1.2 and 1.2 g/100 g, and French classification (Guide de terrassements des remblais et des couches de forme; GTR) of soil samples is A1, B5 and A1, respectively. The washing of soils with lower fine content helps to recover excellent-quality sand and gravel, which are a useful and precious resource. However, residual fine particles are a waste material. In this study, three soil formulations were used for manufacturing earth blocks. These formulations include raw soil, fines and restructured soil. In restructured soil, a fine fraction of soil smaller than 0.063 mm was mixed with 15% recycled sand. Restructuring of soil fine particles helps to improve soil matrix composition and suitability for earth bricks. Compressed-earth blocks of 4 × 4 × 16 cm were manufactured at a laboratory scale for flexural strength testing by using optimum molding moisture content and compaction through Proctor normal energy. Compressive strength tests were performed on cubic blocks of size 4 × 4 × 4 cm. Mechanical testing of bricks showed that bricks with raw soil had higher resistance with a maximum of 3.4 MPa for Lorient soil. Removal of coarse particles from soil decreased the strength of bricks considerably. Restructuring of fines with recycled sand improves their granular skeleton and increases the compressive strength and durability of bricks.

Colloid chemical aspects of paper formation in the presence of nanofibrillated cellulose and cationic starch

A series of experimental tests were carried out to examine colloidal-scale consequences of optional-ly treating nanofibrillated cellulose (NFC) with cationic starches of different charge density and dosage (0.5% or 2.0% by weight), adding that material to a furnish prepared from 100% recycled copy paper, and then subjecting the mixture to very different levels of hydrodynamic shear. Tests included optical microscopy, sediment volume tests, sediment velocity tests, and “percent fines” assessment by means of a fiber quality analyzer (FQA). In addition, the zeta potential and charge demand of the studied materials were evaluated. Optical imaging revealed that cationic starch treatment of the NFC tended to agglomerate it into multiparticle clusters, which sometimes could be mostly redispersed by hydrodynamic shear. Subsequent addition of the starch-treated NFC to the default furnish resulted in much of the colloidal material becoming attached to fibers. Subsequent shearing of the mixtures was at least partly effective in separating the clusters of NFC from the fiber surface, resulting in essentially a two-component mixture. Multiparticle NFC clusters coexisted with the fiber suspension, sometimes attached and sometimes not, depending on the details of treatments. Sediment volume tests showed that systems containing cationic starch-treated NFC tended to have a higher density after settling in comparison to untreated NFC; these findings are consistent with the cationic starch acting as a stabilizer on the solid surfaces, allowing them to slide past each other during the settling process. Application of intense hydrodynamic shear tended to result in denser sediment. Results of tests with the sediment velocity measurement and the FQA percent fines assessment did not correlate well with changes in test conditions considered in this study.

Complex Permittivity of Adobe Verses Frequency and Water Content

The complex permittivity of adobe is measured using a coaxial probe system verses frequency (500 MHz to 7 GHz) and water content (0% to 6%). Measurements are performed using adobe samples collected from abode bricks. The geotechnical properties of the compressed earth bricks are characterized by (1) percentage of gravel, sands, and fines; (2) Atterberg limits; and (3) grain-size distribution. The variation in adobe complex permittivity verses frequency is measured at discrete levels of water content using small adobe samples exposed to controlled levels of constant humidity in an environmental chamber. The typical water content profile verses depth for an adobe brick is also determined.

Petrography and geomechanical properties of some mine waste rocks from the Tarkwaian Group in Ghana: implications for their use as aggregates in general engineering works

This research investigated some mine waste rocks from the southwestern part of the Tarkwaian Group in Ghana to check their suitability for general engineering works using petrography and geomechanical characteristics of the rocks. The rocks were subjected to a total of ten (10) tests, including Aggregate impact value (AIV), Aggregate crushing value (ACV), Loss Angeles abrasion (LAA), Specific gravity (SG), and Water absorption (WA), as well as flakiness and elongation index, slake durability (SD), chloride test (CT), sulphate test (ST), and ten percent fines (TPF). The tests were carried out per the American Society for Testing and Materials guidelines (ASTM). The following average test results were obtained: AIV (7.12%), ACV (15.60%), LAA (23.16%), TPF (269.7 kN), sulphate (0.0215%), chloride (0.00123%), flakiness (39.5%) and elongation (39.4%). The mine waste rocks are dominated by quartz and sericite, according to the petrographic examination and thus, can be classified as quartzites. Except for the flakiness and elongation index tests, all the results were consistent with the ASTM standards. The analysis carried out on the selected mine waste rocks from the southwestern part of the Tarkwaian Group could be catastrophic for heavy engineering works such as roads, bridges, and heavy buildings but can be used for pavements, lightweight buildings, monuments, and decoratives due to the percentage of quartz present to compensate for the weakness posed by the sericite.

Characterization of heat-processed artificial lightweight aggregates from polyethylene terephthalate plastic waste

Plastic waste is an undeniable source of pollution that threatens the existence of the earth’s flora and fauna. The bulk of plastic waste generated globally does not go through the proper methods of disposal but is carelessly discarded into the aquatic or terrestrial environment. Current recycling efforts are largely inadequate and disposal in landfills is still fraught with environmental and land use challenges. The proper disposal of plastic waste, as well as mitigating the environmental, social, and health impacts of extracting natural aggregates can be achieved by incorporating plastic waste as aggregates in the construction industry. This paper presents a characterization of aggregates manufactured from polyethylene terephthalate plastic waste using thermal/mechanical methods. From the cost analysis, 24,341.67 Ugx (6.09 USD) was spent to produce 1 kg of PET aggregates. Morphological, intrinsic and mechanical characteristics of the produced aggregates were established using standard procedures and equipment. The results of morphological characterization indicate an irregular shaped aggregate with smooth surface, a dense graded aggregate with a fineness modulus of 4.25, flakiness index of 26%, elongation index of 16% and particle index of 13. Intrinsic characterization yielded particle density of 1330 kg/m3, bulk density of coarse aggregates of 715 kg/m3 and water absorption of 0.445%. Mechanical characteristics of aggregates were evaluated, with compressive strength of 50Mpa, Aggregate Crushing Value of 37%, Ten Percent Fines Value of 71KN, Aggregate Impact Value of 24% and Aggregate Abrasion Value of 20%. The characteristics of PET aggregates confirm their suitability for application in structural lightweight concrete and rigid pavement. The produced PET aggregates can be considered in mix design as a total or partial replacement of natural aggregates in concrete.

Geotechnical Properties of Fly Ash Blended Expansive Soil: A Review

Fly ash, an industrial byproduct, is used as both a building material and a soil stabilizer due to its pozzolanic properties. Moreover, it is challenging to extrapolate the results based on an inadequate amount of laboratory data because of the non-homogeneous character of the soil and the diversity in the chemical properties of fly ash. This review article fills in the gaps by providing an overview of the existing data related to the geotechnical characteristics of expansive soil stabilized with fly ash. The chemical composition of fly ash is provided in terms of oxides of various elements to help identify the kinds produced in different nations. Additionally, information about the physical and geotechnical characteristics of fly ash blended expansive soil is provided in order to comprehend the influence of the fly ash's chemical composition and the expansive soil's fines percentage. While the geotechnical property comprises Atterberg's limit, compaction, UCS, shear strength, free swelling index, CBR, and consolidation, the physical property includes specific gravity and durability. Shear modulus, damping ratio, and Poisson's ratio are used to describe the dynamic properties of the modified expansive soil. The published data in this field and the research gap will be identified by the researchers with the aid of this article. Doi: 10.28991/CEJ-SP2024-010-06 Full Text: PDF

Regression Analysis on California Bearing Ratio of Selected Soft Soils in Osun State for Pavement Construction

This paper presents a regression analysis on the California Bearing Ratio (CBR) of selected soft soils in Osun State for pavement construction. The lateritic soil used, obtained along Osogbo-Ikirun road, Osogbo-Ilesha road, and West By-Pass Okebale in Osogbo, Osun State, is labeled as locations P, Q, and R, respectively, for easy identification. Geotechnical tests were carried out in line with British Standard (1990), encompassing parameters such as moisture content, specific gravity, particle size analysis, Atterberg limits, Compaction, and California Bearing Ratio. A correlation relationship between CBR and LL, PL, PI, OMC, and MDD was developed using multiple linear regression analysis. Standard Minitab 13 and Microsoft Excel 2013 software packages were utilized for the analysis. The comparison between experimental and predicted CBR values from the derived model yielded R² values of 1, 1, and 0.9741 for locations P, Q, and R, respectively. The analysis underscores that geotechnical properties, including percentage fines for Osogbo-Ikirun road, optimum moisture content for Osogbo-Ilesha road, and specific gravity for West By-Pass soils, can be employed to reliably predict CBR values. The regression analysis indicates a robust quality control measure for the variables PF, OMC, and SG during field compaction. The inclusion of these variables into a comprehensive quality control and specification framework is recommended to enhance the longevity and durability of road pavements.

Physical and mechanical characteristics of pyroclastic soil for the construction of embankments

In the framework of wider research activity on the physical and mechanical behaviour of volcanic soils, this paper reports the results of some laboratory tests on this type of geomaterial. The background of this research is the need for a construction company to possibly use pyroclastic material excavated along a tunnel profile to build railway embankments included in the design of a new High-Speed Train Line near the city of Naples, Italy. However, according to the standards of the National Italian Railways Company, pyroclastic soils cannot be employed as construction materials unless they are supported by a specific testing program demonstrating their good performance. The pyroclastic soil, which is widespread in the project area, is the product of Mt. Vesuvius volcanic activity. It is a coarse-graded soil that includes a significant percentage of non-plastic fines. They should be placed under compact conditions. The experimental campaign was aimed at identifying some physical characteristics that can synthesize the homogeneity of the pyroclastic deposit in terms of shearing resistance. The preliminary results obtained in terms of grading curves, modified Proctor compaction curves, and stress-strain curves from conventional drained triaxial tests are presented and discussed in this paper. The latter were executed on fully saturated specimens after compacting the soil at the optimum water content and on the dry and wet sides of the Proctor curve. The overall initial outcomes of the experimental campaign indicated that this material has acceptable characteristics and is suitable for the construction of railway embankments.

Evaluation of Sylhet sadar upazila's geological formation for groundwater availability

There is sparse of hydrogeological data and insufficient knowledge in many areas of the country reliant on groundwater. Given the exponential expansion in groundwater consumption in recent years, it is imperative to comprehend how groundwater reservoirs respond to both natural and anthropogenic situations. Because of its extensive and unequal distribution, groundwater must be carefully studied in some locations to preserve this precious resource. This study was carried out to evaluate and assess the geological formation and some relevant parameters to enrich the geotechnical information of the study area for future use of groundwater. The soil samples used for the study were obtained from 8 SPT boreholes at 0 to 800 ft.depth at various work stations by percussion drilling method and all laboratory tests were conducted by BS 1377. Drilled soil sample with water was collected in a Polythene bag with a permanent marker pen at 20 ft.intervals of the drilling layer to perform a sieve analysis test. Percentage fines decreased with an increase in boring depth and curves were closely packed homogeneity. The quantity of free silt and clay progressively reduced and coarsen materials were formed with the increase in boring depth. Results show that soil particle sizes increase with boringdepth up to the upper surface of it. However, the area is suitable in terms of groundwater availability.

Palmer amaranth (Amaranthus palmeri) control affected by weed size and herbicide spray solution with nozzle type pairings

Abstract Palmer amaranth can grow 4.2 mm in height per degree day; hence, delays of a few days in weed control deployment can result in applications of herbicides to weeds that are larger than those for which the herbicide label recommends. Therefore, it is critically necessary to understand the effect of plant size at the time of herbicide application in conjunction with herbicide spray solution and nozzle type pairings on the effectiveness of weed management programs in the Enlist E3 and XtendFlex production systems. Field experiments were conducted in 2020, in no-crop conditions, at two locations in Arkansas, to evaluate the influence of Palmer amaranth size on its control with glufosinate, dicamba, and 2,4-D applied alone and in mixture with specific nozzle pairings as mandated by label requirements. Also, a laboratory experiment was conducted to evaluate the droplet size and velocity of the spray solutions and nozzles used in the field experiments. A 5- and 10-percentage point reduction in control was observed when dicamba (66%) and 2,4-D (63%) were applied alone, respectively, compared with those herbicides mixed with glufosinate (71% and 73%, respectively). Palmer amaranth density increased to 55, 73, 100, 115, and 140 plants m−2 when plants were sprayed at heights of 15, 25, 41, 61, and 76 cm, respectively, compared with plants that were sprayed when they were 5 cm tall (9 plants m−2). Nozzle type did not affect weed control or density. The percentage of driftable fines increased when a mixture of glufosinate and 2,4-D were used compared with 2,4-D alone. Effective short-term and long-term chemical control of Palmer amaranth will require growers to correctly time their weed management practices and overlay residuals, and expect the need for sequential applications.

Asteroid regolith strength: Role of fine-fractions

Most smaller asteroids (<1 km diameter) are granular material loosely bound together primarily by self-gravity known as rubble piles. In an effort to better understand the evolution of rubble-pile asteroids, we performed bulk measurements using granular simulant to study the effects of the presence of fine grains on the strength of coarse grains. Our laboratory samples consisted of fine–coarse mixtures of varying percentages of fine grains by volume of the sample. We measured the material’s angle of repose, Young’s Modulus, angle of internal friction, cohesion, and tensile strength by subjecting the samples to compressive and shear stresses. The coarse grains comprising the fine–coarse mixtures ranged from 1 mm to 20 mm (2 cm) and the fines were sieved to sub-millimeter sizes (<1 mm). The measured angles of repose varied between 32°–45° which increased with increasing fine percentage. In compression, samples generally increased in strength with increasing fine percentage for both confined and unconfined environments. In all cases, the peak strengths were not for purely fine grains but for a mixture of fine and coarse grains. Shear stress measurements yielded angles of internal friction ranging between 25° and 45° with a trend opposite that of the angle of repose, 300–550 Pa for bulk cohesion, and 0.5–1.1 kPa for tensile strength. Using other published works that include data from telescopic and in-situ observations as well as numerical simulations, we discussed the implications of our findings regarding rubble-pile formation, composition, evolution, and disruption. We find that the presence of fine grains in subsurface layers of regolith on an asteroid (confined environment) aids the avoidance of disruption due to impact. However these same fines increase an asteroid’s chance to disrupt or deform from high rotation speeds due to reduced grain interlocking. In surface layers (unconfined environments), we find that the presence of fine grains between coarse ones generates stronger cohesion and aids in the prevention of mass loss and surface shedding.

Emissions and combustion characteristics of torrefied wood pellets

The influence of torrefaction temperature on the durability, combustion characteristics, and emissions of CO, CO2, NOX, and particulate matter (PM) from biomass pellets was studied. The pellets were torrefied under inert conditions at 225, 250, and 300 °C for 60 min. Physical properties, such as weight loss, fines percentage, pellet durability index (PDI), and water absorption, were evaluated using ISO standards. The weight loss increased with higher torrefaction temperatures. Torrefied pellets had lower water absorption than untreated pellets. Fines percentage increased with torrefaction temperature while PDI decreased. Torrefied pellets at 300 °C had the lowest PDI (82.7%), while 225 °C had the highest (98.0%). The energy density and heating values increased with torrefaction temperature from 22.0 MJ/kg at 225 °C to 29.9 MJ/kg at 300 °C compared to 18.9 MJ/kg for untorrefied pellets. There were reductions in CO, CO2, and NOX emissions with an increase in torrefaction temperature while PM slightly reduced. This study found that torrefied biomass pellets had lower CO2 emissions than raw pellets.

Overview of the Empirical Relations between Different Aggregate Degradation Values and Rock Strength Parameters

The aggregates are essential materials in civil engineering, they are used for railway and road constructions, for hydraulic engineering but they are also the base material of concrete. The crushed stones are exposed to several effects during their lifespan. Therefore, several tests were developed to evaluate their performance. One of the most important aspects is the resistance to degradation. However, degradation tests require special types of equipment and usually take longer than common strength tests which are more likely to be available for rock materials. Therefore, the empirical connections between strength and degradation values can be extremely useful in practice. The paper aimed to collect all available relationships and datasets from the literature that presents the relations between these different parameters – such as Aggregate Impact Value (AIV), Aggregate Crushing Value (ACV), Ten Percent Fines Value (TFV), Los Angeles Abrasion Value (LAAV), and micro-Deval Coefficient (MDE) – and rock strength parameters – such as Uniaxial Compressive Strength (UCS) and Point Load Strength Index (IS(50)) – and to provide the best-fit formula for different rock types. The paper also highlights the difficulties and limitations of the compared relationships.

58 Effects of Pellet Quality on Growth Performances of Pigs When Fed Diets During Varying Weight Ranges

Abstract The objective of these experiments was to determine if the importance of pellet quality was dependent on pig weight ranges. Therefore, a total of 350 grow-finish pigs (line 600 × 241; DNA) were used in 3 separate experiments. Each experiment was conducted as a randomized complete block design. Pigs were weighed before the onset of each experiment and split into 7 blocks based on average body weight, resulting in 7 replications per treatment. For Exp. 1, 2, and 3, pigs were fed treatments for 20 days from 43 to 68 kg, 21 days from 81 to 107 kg, and 20 days from 118 to 144 kg, respectively. Pelleted diets for Exp. 1, 2, and 3 were steam conditioned at approximately 83, 77, and 67°C, respectively and subsequently pelleted with a 30-horsepower pellet mill (1012-2 HD Master Model, California Pellet Mill, Crawfordsville, IN). For Exp. 1 and 2 diets were pelleted with a 4.8 × 31.8 mm (L:D 6.7) die while a 4.8 × 57.2 mm (L:D 12) die was used for Exp. 3. Treatments consisted of a mash diet and pellets with fines inclusion rates of 9-16, 41-47, 60-68, and 84-91%. For Exp.1, pigs fed pellets with 12.5% fines had improved (P &amp;lt; 0.05) G:F when compared with those fed the mash diet. Pig ADFI increased (linear, P = 0.006) as percent fines at the feeder increased. Pig G:F decreased (linear, P = 0.002) as percent fines increased at the feeder. For Exp. 2, pigs fed pellets with 15.5% fines had improved (P &amp;lt; 0.05) G:F compared with those fed the mash diet. Pig ADFI increased (linear, P = 0.016) when fed pellets with increasing percent fines at the feeder. Pig G:F decreased (linear, P = &amp;lt; 0.001) as fines percentage increased at the feeder. For Exp. 3, pigs fed pellets with 9.6 and 41.8% fines had increased (P &amp;lt; 0.05) G:F when compared with those fed mash diets. Pig G:F decreased (linear, P = 0.005) as pellet fines percentage increased at the feeder. In conclusion, feeding pigs 12.5, 15.5, and 9.6% fines in Exp. 1, 2, and 3 improved G:F by 3.9, 5.4, and 9.1%, respectively, compared with pigs fed mashed diets. Increasing the percent fines from 12.5 to 90.4%, 15.5 to 86.0%, and 9.6 to 83.6% reduced G:F of pigs by 5.7, 7.7, and 5.6% for Exp. 1, 2, and 3, respectively.

Study of Correlation between CBR and Certain Physical Characteristics of Lateritic Gravels

The aim of this work is to study the possibility of establishing a correlation between the CBR value and the percentage of fines, the plasticity index, the Proctor density and the water content at the Proctor optimum of laterites that can be used in pavement layers. To this end, data was collected on the physical (percentage of fines, Atterberg limits) and mechanical (Proctor and CBR) characteristics of lateritic gravels available in Togo. In accordance with current standards, the data collected was analysed using Excel software and correlated using Matlab, with CBR as the explained variable and percentage of fines, plasticity index, Proctor density and water content at the Proctor optimum as the explanatory variables. A total of 479 test results on lateritic gravels were identified and used to carry out this study. The results of this study show that it is possible to correlate the CBR as a function of the percentage of fines and density using Matlab software. This correlation is obtained in the form of a bi-harmonic surface linking the CBR to the density and the percentage of fines, which is the solution of a partial differential equation solved by the weak form (numerical approximation using finite elements or finite differences) and not by the strong form (writing a formal solution). Keywords: laterite, road pavement, CBR, correlation

Vibration Sensor in Multiphase Flow Measurement

The solid waste generated in the steel industry are predominantly recycled via the agglomeration making route. In recent times, the amount of fines percentage has increased in sinter making, thereby affecting the bed permeability which eventually affects sinter quality. Hence, sinter bed permeability is to be monitored continuously. Currently the conventional infrared based velocity measurement is being used for this purpose. The permeability is being calculated based on the flow velocity of flue gases. The current paper is focused on the development of low cost novel vibration sensor for flow measurement to monitor permeability. The measurements are showing with good accuracy (96%) in comparison with the conventional technique. The design and development along with the results are discussed in detail in this paper.

İnce Toprak İçeriğin Zeminin Kayma Mukavemeti Parametrelerine Etkisi

The shear strength of the soil is a crucial factor in the structure's failure. Before any engineering structure is built on the soil, the shear strength characteristics must be thoroughly examined in order to reduce the calamity of structural collapse. The current study investigates the influence of varied percentages of fine material on soil shear strength. The soil sample consists primarily of sandy and clay soil. The study looked into the impact of fines on shear strength metrics (friction angle and soil cohesion). Several journal papers and articles were reviewed for this study. Based on the findings of several papers, the flow chart was created to describe the effect of the percentage of fine content in the soil and how it affects shear strength parameters. The shear strength parameters of sandy soil are significantly dependent on the percentage of fines in the mixture and the type of fine mineralogical composition. Both soil shear strength parameters increase at a substantial and apparent pace as compared to the particle content and additive increases in clay soil.

Effect of Fines on Strength of Granular Soil Reinforced with Geosynthetics

Geosynthetics (GSN) are polymeric products used in Geotechnical Engineering for the purpose of improving the properties of the insitu soil. In this project, experimental work was carried out to determine the influence of presence of fines within granular soil on the CBR strength of soil reinforced with different GSN (Woven geotextile, Non-woven geotextile, Geogrid and Geonet). Two types of granular soil in disturbed state containing varying percentage of fines were selected from in and around the Chennai region. Soil type 1 contains high fines of about 40% (SHF) whereas soil type 2 contains less fines of about 7% (SLF). Unsoaked CBR (U-CBR) test was carried on unreinforced soil and on soil reinforced with different GSN placed at varying depths of D/5, 2D/5, 3D/5 and 4D/5 from top of soil (D is the total depth of soil), to determine the ideal depth of placement of GSN within SHF and SLF. Soaked CBR (S-CBR) test was carried on unreinforced soil and on soil reinforced with different GSN placed at an ideal depth determined from U-CBR test. Based on the experimental results, ideal depth of placement of GSN for SHF and SLF was found to be D/5 and 3D/5 respectively from top of the soil and Geogrid was found to be the best geosynthetic for reinforcing the granular soil containing high fines and less fines.

Experimental and Numerical Analysis of Sustainable Use of Steel Slag for Geogrid-Encased Column Involving Its Clogging Effects

This study investigates the sustainable use of steel slag for a geogrid-encased column involving its reinforcement and clogging effects on its consolidation performance in soft foundations through model tests and 3D hydromechanical-coupled finite element analyses. The 3D finite element model is first validated according to test results of an untreated and treated soft soil foundation. Then, a parametric study investigating the effect of clogging on the performance of the geogrid-encased steel slag column (GESSC) is carried out. Steel slags mixed with different percentages of fine (0%, 10%, 20%, and 40%) are used to simulate various clogging conditions. The numerical study shows that the percentage of fines in the GESSC has a notable effect on the dissipation of excess pore water pressure as well as foundation consolidation.

Shrink–swell index prediction through deep learning

Growing application of artificial intelligence in geotechnical engineering has been observed; however, its ability to predict the properties and nonlinear behaviour of reactive soil is currently not well considered. Although previous studies provided linear correlations between shrink–swell index and Atterberg limits, obtained model accuracy values were found unsatisfactory results. Artificial intelligence, specifically deep learning, has the potential to give improved accuracy. This research employed deep learning to predict more accurate values of shrink–swell indices, which explored two scenarios; Scenario 1 used the features liquid limit, plastic limit, plasticity index, and linear shrinkage, whilst Scenario 2 added the input feature, fines percentage passing through a 0.075-mm sieve (%fines). Findings indicated that the implementation of deep learning neural networks resulted in increased model measurement accuracy in Scenarios 1 and 2. The values of accuracy measured in this study were suggestively higher and have wider variance than most previous studies. Global sensitivity analyses were also conducted to investigate the influence of each input feature. These sensitivity analyses resulted in a range of predicted values within the variance of data in Scenario 2, with the %fines having the highest contribution to the variance of the shrink–swell index and a relevant interaction between linear shrinkage and %fines. The proposed model Scenario 2 was around 10–65% more accurate than the preceding models considered in this study, which can then be used to expeditiously estimate more accurate values of shrink–swell indices.
