Abstract

The Life Cycle Assessment (LCA) of asphalt pavements is an essential tool for reducing environmental impacts. The definition of the functional unit (FU) within LCA can significantly influence the results, affecting the assessment of greenhouse gas (GHG) emissions and, consequently, the selection of asphalt mixtures. In this context, this study aims to analyze the impact of different functional units on the selection of asphalt mixtures for road pavements, considering the phases of raw material extraction, material production, mixing, and construction. To this end, the mechanical behavior of two distinct asphalt mixtures was evaluated under two different loading conditions, and their contributions to climate change were assessed using three functional units: t CO₂ eq/km of roadway, kg CO₂ eq/t of HMA, and kg CO₂ eq/m³ of HMA. The results indicated that asphalt mixtures with a higher resilient modulus require thinner pavement layers, leading to lower GHG emissions. However, when asphalt mixtures are analyzed individually and compared, no clear pattern in GHG emissions is observed, reflecting the specific characteristics of each production process. Additionally, it was found that the environmental impact varied according to the adopted functional unit, demonstrating that this choice can significantly influence decision-making regarding the selection of asphalt mixtures in terms of their contributions to climate change. It was concluded that the selection of the FU in pavement LCA should be aligned with the study's objective and the context of the analysis, as an inadequate choice may compromise the selection of asphalt mixtures.

Abstract

Passenger satisfaction must be measured by operators providing high-speed train services, as it is directly related to passenger loyalty, which in turn ensures the business's sustainability. This study aims to measure passenger satisfaction with the Jakarta-Bandung high-speed train by developing a model that considers various factors significant in influencing user satisfaction. The quantitative method was developed by distributing questionnaires to 300 respondents, and the results were analyzed using SEM. The results of this study prove the existence of a model built from 5 (five) dimensions: the availability of information, accessibility, train comfort, emergency actions, and responses to complaints. The results of this study are expected to provide recommendations to the operator of the Jakarta-Bandung High Speed Train to evaluate the factors of 5 (five) dimensions that are considered important in forming a user satisfaction model for the service using a performance analysis matrix (IPA Diagram). According to the results of the IPA diagram, it is evident that the most urgent task for the operator is to consolidate with third parties related to the availability of modes to serve passengers who will continue their journey to Bandung, particularly for work and tourism purposes.

Abstract

This paper presents a methodology for assessing the stability of stoping chambers and inter-chamber pillars (ICPs) during underground mining of ore bodies with varying dip angles. The objective is to determine optimal parameters for excavation elements (chamber width and pillar spacing) that ensure the stability of the mining system under fractured rock mass conditions. The Zhezkazgan deposit’s geomechanical properties were used as the modeling case study. The methodology includes geotechnical core mapping (with RQD, Q-system, and GSI classifications), laboratory strength testing, field–laboratory correlation, and numerical modeling using the finite element method. Particular focus is placed on the sensitivity of stability to variations in GSI, depth, and excavation geometry. The results indicate that increasing the dip angle significantly reduces the stability of both chambers and pillars. The novelty of this study lies in the comprehensive assessment of structural factors and excavation geometry on mass stability under site-specific geological conditions.

Abstract

This paper evaluates the effectiveness of a crystalline hydrophilic additive and chemical microcapsules in enhancing concrete’s freeze-thaw resistance at both material and structural levels. Three concrete mixes were tested: a reference mix, one with the crystalline additive and one with microcapsules. Cubic specimens were tested for compressive strength, water absorption and relative dynamic modulus of elasticity before, after and during 56 freeze-thaw cycles (according to CEN/TR 15177). The reinforced concrete beams underwent the same freeze-thaw regime and were tested under displacement-controlled cyclic loading to evaluate residual capacity and serviceability. Although both additives improved freeze-thaw resistance, beams with the microcapsule performed better on most criteria, including increased stiffness (+14%), load-bearing capacity (up to +22%) and ductility after freeze-thaw loading. Notably, all mixes showed an unexpected increase in compressive strength after cycling. Although the microcapsules provided the best overall performance, the crystalline additive was more effective in reducing water absorption. The study highlights the practical applicability of microcapsules for structural elements and demonstrates their potential to improve performance properties under harsh environmental conditions. The research novelty lies in the dual-level evaluation – material and structural – and the systematic comparison of two innovative additives, allowing a more comprehensive understanding of their performance under freeze-thaw conditions.

Abstract

The aim of this study is to determine the possibility of producing non-autoclaved foam concrete of grade M35 with a density of 900 kg/m³. A distinctive feature of this development is the testing of twin samples from the same batch: some were steamed in a chamber at 90 °C under normal atmospheric pressure, while others were autoclaved at a pressure of 8 bar and a temperature of 170 °C. It was established that ordinary natural feldspar sands with a fineness modulus ranging from 1.43 to 2.45, containing quartz below the standard-regulated levels, can be used in the production of non-autoclaved foam concrete. It is not possible to obtain non-autoclaved D900 foam concrete of grade M35 strength using only cement, sand, and foaming agent. To achieve the specified strength, it is necessary to use coarse sand with a fineness modulus (FM) greater than 3, subjected to short-term grinding to reduce the FM to recommended values, and to additionally introduce sol-gel liquid glass. The novelty lies in the experimental confirmation of the features of strength formation in cellular concrete under both non-autoclaved and autoclaved curing conditions. Comparative tests showed that high strength in cellular concrete is achieved only when a chemical bond forms between the products of cement hydrolysis and hydration with quartz sand grains—conditions made possible through autoclaving.

Abstract

The ground motion amplification effect influenced by diverse topographic and geological conditions was investigated to enhance the seismic design standards for mountain structures. A comprehensive series of two-dimensional and three-dimensional numerical simulations was conducted. These simulations utilized idealized and real-world topographic models, meticulously considering various critical parameters, such as platform height, width, slope, surface angle, and soil properties. The results reveal that topographic and geological factors both significantly impact the ground motion amplification effect, with the maximum amplification factors frequently surpassing those stipulated by the current Chinese seismic code. Based on these findings, a refined and modified formula was developed for calculating the ground motion amplification factor that integrates the influences of height, width, slope, and geological conditions. The validity and feasibility of this modified formula were substantiated thoroughly through detailed comparisons between the actual observed values and the suggested values, demonstrating its potential to improve the safety and reliability of seismic design in mountainous regions substantially.

Abstract

This research aims to investigate the effect of hematite powder on the first cracking and ultimate torsional resistance, crack patterns, and angle of twist of high-strength concrete beams strengthened with steel fibers under pure torsion. The study was carried out in two stages. The first stage consisted of six hollow cross-section beams to determine the best ratio and type of steel fiber that provide the highest torsional resistance. The second stage aimed to find the optimal ratio of hematite powder that can improve the torsional resistance of high-strength steel fiber-reinforced concrete without causing implementation problems. This was achieved by testing six hollow cross-section beams with hematite ratios of 0.5%, 1%, 1.5%, 2.5%, 3.5%, and 5% as cement replacements. The results showed that using hematite powder up to 2.5% as a cement replacement, combined with a 1.5% mix of steel fibers (50% end-hooked and 50% corrugated), increased both the first cracking and ultimate torque, along with a relative increase in the angle of twist. Additionally, it delayed crack development, reduced crack width, and increased the number of cracks at failure.

Abstract

Land use and land cover change is one of the main drivers transforming high Andean ecosystems in Colombia. This study examines the spatial dynamics of land use in the La Cocha Ramsar Wetland between 1989 and 2020 and projects land cover scenarios to the year 2050 using spatial modeling techniques. Land cover maps for 1989 and 2020 were developed using satellite imagery and photo-interpretation, following the CORINE Land Cover methodology adapted for Colombia. A transition matrix and change indicators defined by the Institute of Hydrology, Meteorology and Environmental Studies (IDEAM) were used for multitemporal analysis, allowing the identification of processes such as forest fragmentation and recovery, agricultural expansion, and the spread of pastures. Future projections were modeled with the Land Change Modeler (LCM) module in the IDRISI Selva software, incorporating biophysical and socioeconomic variables with significant association (Cramér’s V > 0.4). Eight dominant transitions were identified, and change potential maps were generated. The model was validated through random field sampling and a confusion matrix analysis, yielding a Kappa index of 0.76, indicating strong agreement between simulated and observed data. Results show that 91.06% of the area remained unchanged, while 8.94% underwent transformations attributed to human activities. A net increase of 66.75 ha in dense forest is projected by 2050, along with growth in fragmented forest areas and agro-pastoral mosaics.

Abstract

This research introduces an analytical procedure for simulating the nonlinear behavior of single piles and pile groups under lateral loads in multi-layered, heterogeneous soil. The methodology combines the finite element method, the p-y technique, and the p-multiplier concept. Duncan and Chang's hyperbolic equation, characterized by three parameters, was employed to represent the soil reaction for sand and clay soils. A newly proposed equation to derive p-multipliers as a function of a pile's location and spacing within a pile group. Its predictions show satisfactory agreement with those from existing methods. The procedure was implemented in a computer program to enable rapid and accurate computation. The proposed program validation involved comprehensive comparisons against results from field load tests and sophisticated 3D finite element analyses. These comparisons confirm that the developed program is both reliable and efficient, making it well-suited for preliminary design stages. A subsequent parametric study on a single pile revealed that replacing soft upper clay with a compacted sand layer significantly decreases lateral deflection and bending moment. For the cases examined, an optimal compacted layer thickness of three pile diameters and a stiffness 5.6 times that of the native soft clay were identified.

Abstract

This study conducts a numerical analysis on the shear performance of reinforced concrete beams retrofitted with fiber-reinforced polymer (FRP) bars with embedded through-section (ETS) technique. The study uses 3D nonlinear finite element method (FEM) and evaluates the shear features of ETS-FRP-strengthened beams in failure modes, shear capacity, stiffness, and ductility. The FE analyses consider the effects of key design parameters, including transverse steel stiffness (Eswρsw), ETS-FRP bar stiffness (Efρf), compressive strength of concrete (f’c), beam geometry, and the values of shear span-to-effective depth (a/d) ratio. Consequently, ETS-strengthened beams with higher concrete strength (f’c) or greater total rigidity of ETS and transverse reinforcement (Efρf + Eswρsw) showed notable improvements in stiffness and load-carrying capacity, with average increases exceeding 20%. The enhancement in shear strength from increased shear reinforcement stiffness is less pronounced in specimens with high concrete strength than in those with lower strength. ETS-strengthened beams with T-shaped sections exhibit more effective performance and safer failure modes. An enhancement in the a/d ratio reduces the stress in ETS bars but results in more ductile failures. This study also proposes a new analytical formulation for determining the maximum shear resistance of ETS-intervened beams, accounting for all failure modes. The model achieved an average predicted-to-tested shear maximum force ratio of 0.93 along with a coefficient of variation of 26%, demonstrating improved accuracy compared to existing models.
