The AASHTOWare Pavement Mechanistic-Empirical Design (PMED) software is based on mechanistic response algorithms, and empirical relationships where measurable surface distresses are related to the mechanistic responses for pavement design analysis. PMED uses the soil resilient modulus to characterize the subgrade layer and recommends providing a resilient modulus of at least 69 MPa. This research studied six projects to assess subgrade characteristics using a Falling Weight Deflectometer and a Dynamic Cone Penetrometer. Resilient moduli were back-calculated from the FWD data and also calculated from a correlation with the Dynamic Cone Penetrometer results. The effect of subgrade characterization on PMED design analysis was then assessed using these subgrade resilient moduli. Recommendations were made regarding the selection of design subgrade resilient modulus.

Trees possess the ability to protect outdoor cultural heritage by regulating microclimates in their surroundings. However, the specific influence of variations in tree height on heritage conservation remains uncertain. This study conducted simulations to compare the hygrothermal conditions of the Nanjing CityWall with varying tree heights (H = 7.5 m, 12.5 m, and 17.5 m) and assessed the spatial and temporal distribution of wall salt weathering risk. The results were as follows: 1) Increasing tree height led to a decrease in the average temperature and fluctuation range of the city wall surface, alongside an increase in the average surface water content. The fluctuation range of water content decreased in winter, spring, and summer but increased in autumn;2) Higher tree height enhanced trees' effectiveness in reducing the frequency of salt weathering on the wall surface. These results provide insights for the conservation of outdoor heritage and the management of vegetation around heritage sites.

To create an eco-friendly environment, research is now primarily focused on reducing industrial and agricultural waste. SCBA, or sugarcane bagasse ash, is a fibrous byproduct of the sugarcane industry. The residual sugarcane, known as bagasse, is burned at high temperatures under uncontrolled conditions to produce ash after the juice from the sugarcane has been extracted. Already, this waste product is seriously polluting the environment. The silica in the bagasse ash reacts with the cement's constituent parts upon saturation to provide the cement extra characteristics including defense against rusting and chloride. As a result, adding ash to concrete additionally reduces expense all while enhancing quality and eradicating environmental harm. It makes the concrete more resilient. In the current study, the impact of bagasse ash on concrete strength is examined. The purpose of this work is to shed some light on the scientific literature done on SCBA's potential as a replacement for other concrete ingredients. The impact of SCBA on both plastic and hardened concrete properties was addressed in this study and various tests on physical properties and chemical properties of SCBA are also included. Different papers have studied to check the actual properties and various factors by using SCBA in construction.

Using vegetation for ground improvement is a sustainable, environmentally friendly, and cost-effective approach. The increase in shear strength and stiffness of soil is mainly due to the suction induced by root water uptake and the mechanical reinforcing effect provided by the tree roots. The root water uptake of the tree relies on the physiology of the tree and environmental parameters. The total leaf area, number of stomata present in a leaf, root system, spatial distribution of roots, etc. influence the root water uptake as the physiological parameters. In this study, an empirical correlation was developed between the root water uptake (Sp) and total leaf area (TLA) of Alstonia macrophylla (Attonia). A Potometer, which can be used to measure the transpiration of a small tree, was kept in a controlled environmental condition to eliminate the influence of extraneous variables. Previous studies have revealed that more than 99% of root water uptake is lost through leaf transpiration. Consequently, it was assumed that the amount of water lost through transpiration is equivalent to the amount of water taken up by the roots at any given time. This assumption leads to approximating the root water uptake rate by measuring the transpiration rate using a Potometer, which uses the traveled distance of an air bubble in a small glass tube.

Ordinary Portland Cement (OPC) has been extensively employed to stabilize soft clay. However, OPC exhibits inefficiency in treating high water content soft clay, necessitating a high dosage of OPC and resulting in significant CO2 emissions. Expansive agent (EA) is a cement additive that, during the hydration process, expands and fills some of the pores in the matrix. It has the potential to enhance the strength performance of OPC-treated soft clay. However, commercially available EA is currently costly and challenging to apply in cement-stabilized soft soil. In this study, EA derived from waste, including freshwater sludge (FS) and carbide slag (CS), was developed, and the feasibility of utilizing this waste-based EA in soft clay stabilization was examined. The EAs (both FS-CS based EA and commercial EA) were mixedwithOPCand ground granulated blast-furnace slag (GGBS) for the stabilization of soft clay. The findings revealed that both FS-CS-based EA and commercial EA enhanced the unconfined compressive strength (UCS) of stabilized clay. FS-CS-based EA exhibited significantly better performance than the commercial EA in both OPC-stabilized clay and GGBS-stabilized clay. The strength enhancement effect of the FS-CS-based EA on GGBS-stabilized clay was significantly more pronounced than its effect on OPC-stabilized clay.

Research has been carried out to study the effects of new tunnelling on an existing adjacent tunnel to ensure the safety and serviceability of tunnels. Prior studies on twin-tunnel interaction have mostly centred on simplifying perpendicularly crossing tunnelling in a single-layered soil stratum. New tunnel excavation beneath an existing tunnel at different skew angles in two-layered strata can lead to different patterns of stress redistribution and adverse impacts on the existing tunnel. In this paper, results of three-dimensional centrifuge and numerical modelling carried out to study the twin-tunnel interaction with varying advancing orientations and layered soils will be reported. The influence of new tunnel excavation on an existing tunnel was simulated in-flight by controlling both the tunnel weight and volume losses. An advanced hypoplastic constitutive model that can capture stress-, path, and strain-dependency of soil behaviour is utilised for numerical back-analyses and parametric studies. Cases investigated include twin-tunnel interaction at three different skew angles (30 degrees, 60 degrees, 90 degrees) in a uniform sand layer and at skew angle of 90 degrees in two-layered sand with different relative densities and thicknesses. Distinct load redistribution patterns will be presented to explain deformation mechanisms of the existing tunnel at different tunnel advancing skew angles to highlight the effects of tunnelling orientation. The results of perpendicularly crossing tunnelling in twolayered sand will also be reported and compared to reveal the influence of layered soil. The findings and new insights can help engineers better estimate advancing tunnelling effects on existing tunnels and enhance the safety of tunnel construction.

Aluminum possesses numerous advantages as a construction material such as a high strength-to-weight ratio, excellent durability, corrosion resistance, recyclability, and formability. Nevertheless, due to the limited knowledge of their buckling behavior and efficient design recommendations, aluminum alloys are yet to be accepted widely in structural applications. To enable a more efficient design for aluminum structural members, this study aims at analyzing the buckling behavior of aluminum extrusions through experimental studies. With the specific objective to investigate the local buckling instability of aluminum extrusions, four series of stub column tests with axial compression and ten short beam-column tests with eccentric compression were performed on Circular Hollow Sections (CHS) with 6061-T6 aluminum alloy. The initial geometrical imperfections of the specimens were measured by using professional 3D scanners and the material properties were obtained through tensile coupon tests.

With the advancement of mass-timber construction technologies, the requirement for Performance-Based Fire Design (PBFD) becomes paramount. PBFD is known to save costs, but in practise, design changes leading to re-design can cost more than any savings that might be had. To combat this, interdisciplinary understanding and coordination must be improved. The authors found that there were little to no holistic guides for architects on the fire dynamics of timber compartments, only guides on how to use prescriptive codes. Rather than overbearing the reader with complex physics, the aim of the paper is to provide architects and other professionals with a holistic reference on the relationship between architectural features and the fire dynamics of timber compartments. This is done by demonstrating through the holistic review of 33 full-scale timber compartment tests, an analysis of the relationship between common architectural changes (opening sizes, finishes, and occupational use among others) and their impacts on fire performance (time to flashover, intense burning durations, maximum temperatures reached, etc.). Both a qualitative review of observations made during the tests and plots comparing architectural metrics against fire dynamic metrics are made, as well as their corresponding correlation coefficients. It was found that floor area and ceiling height have a significant relationship with maximum temperatures and Heat Release Rate (HRR). It was found that exposed timber compartments had faster times to ignition and longer intense burning periods. Correlation values indicate that exposed timber ceilings have a greater relationship with fire dynamics than exposed timber walls. This paper reveals to the reader the significance of architectural changes on fire dynamics and the complex understudied nature of timber compartment fires. Architects and owners building a modern mass-timber structure will become acutely aware of how design changes will likely instigate furthe

Soil conditioning is crucial in maintaining stability during earth pressure balance (EPB) shield tunneling. Understanding the properties of the soil conditioner and its impact on soil is essential for ensuring the safety of the tunneling. This study focuses on investigating the penetration behavior of foam, a commonly used soil conditioner, in saturated sand. Experiments were conducted using a sand column device to simulate the foam penetration process in different sand beds. The experimental results reveal that foam penetration in the sand forms two linear pore pressure drop regions with different gradients, with the foam penetration area occupying the majority of the pore pressure. The foam penetration also introduces a flow velocity reduction in the sand column, resulting in blocking. Furthermore, a notable correlation emerged between the foam penetration velocity and the hydraulic gradient, akin to Darcy's law but with a different expression equation. The findings contribute to enhancing our understanding of soil conditioning in EPB shield tunneling and support the design of safer and more efficient tunneling processes.

The way projects are planned, constructed, and managed in the built asset industry is currently being transformed by the utilization of Building Information Modeling (BIM). BIM has emerged as a powerful set of policies, processes and tools that provides a collaborative ecosystem for stakeholders to share and manage project information. However, the digital nature of information models presents unique challenges, particularly in terms of data integrity and authentication. This paper aims to review the existing literature on the authentication of BIMs in construction projects and explore the potential of adding digital signatures to BIM models as a solution to address identified challenges around data compliance and integrity. The paper will explore the benefits of digital signatures in terms of enhancing trust, accountability, traceability, and transparency in construction projects by ensuring that the digitally signed content has not been tampered with and that they originate from a verified source. This is crucial in a collaborative environment where multiple stakeholders and teams contribute to creating, modifying, and using the model. Furthermore, digital signatures could be beneficial in resolution of conflicts like contractual disputes by providing a non-reputable, verifiable, and traceable record of model changes and approvals.
