      <title>NIMBY effect algorithm for railway construction in functional urban areas: A Polish case study</title>
      <link>https://trid.trb.org/View/2646189</link>
      <description><![CDATA[The limitation of land causes conflicts over how it is used, particularly in functional urban areas. Although Not in My Backyard (NIMBY) effects are often associated with established residential neighborhoods, they may also arise in rapidly developing suburban and peri-urban zones, where transport investments intersect with existing settlements and ongoing land-use change. Due to their specific nature, projects for new railway lines are more likely to receive a negative reception, because they can adversely affect property values, cause buyouts and expropriations, and introduce significant changes to a settlement’s spatial layout. The feasibility of different infrastructure project variants could be affected by varying levels of risk. Therefore, the occurrence of the NIMBY phenomenon necessitates a precise, standardized approach to its assessment. For this reason, the main aim of this study is to develop an algorithm to assess the scale of NIMBY responses for railway construction investments in densely populated Functional Urban Area (FUA) commuting zones, involving multicriteria spatial analysis. The algorithm is tested in the selected Lomza FUA railway construction project located in northeastern Poland. The project involves both the restoration of the railway line and its construction in a new location. This study highlights the analyses of spatial structural change that are crucial for understanding local resistance, since in suburbanizing areas, the intensity of NIMBY is strongly correlated with demographic shifts and patterns of land-use transformation. The Lomza FUA case confirms this.]]></description>

      <title>Best Practices for Pavement Widening</title>
      <link>https://trid.trb.org/View/2676936</link>
      <description><![CDATA[Premature pavement failures have occurred on several widening projects, including shoulder widenings, conversion of two-lane roadways to Super 2 sections, and other safety enhancements. Repairing these early failures is time-consuming, expensive, disrupts traffic, and poses safety hazards. Key contributing factors include poor-quality materials, poor joint construction, and inadequate drainage. These issues could have been avoided through proper pavement condition assessment, design, and construction practices, but detailed guidance on which methods to employ and which can be project specific is not readily available to district personnel. Therefore, there is a need to document and implement better widening practices across the Texas Department of Transportation (TxDOT).]]></description>

      <title>Is the policy of massive transportation infrastructure construction hindering China’s carbon reduction?</title>
      <link>https://trid.trb.org/View/2639485</link>
      <description><![CDATA[With the goals of carbon neutrality and peaking emissions, China faces balancing economic growth with emission reductions. Transportation infrastructure significantly affects carbon emissions while enabling regional development. This study examines how road construction in China from 2000 to 2012 impacted county-level carbon emissions, using China’s National Highway Project as a natural experiment with a DID approach. The shortest path network addresses endogeneity from non-random routing. Firstly, according to the findings, the construction of transportation infrastructure has significantly increased carbon emissions (CE) in surrounding counties. Secondly, results show transportation infrastructure construction increased surrounding county carbon emissions (CE) through industrial agglomeration and urbanization. Thirdly, impacts were more significant in eastern counties and non-traditional industrial cities. Policy suggestions aim to reconcile infrastructure and climate goals.]]></description>

      <title>Cement Treated Base by Cold in Place Recycling Technology for Rural Roads</title>
      <link>https://trid.trb.org/View/2652203</link>
      <description><![CDATA[A large proportion of India’s villages have been connected with Water Bound Macadam (WBM) or bituminous roads. Rural roads usually have low volume of traffic, consisting mostly of light transport vehicles with less frequency of heavy traffic. Maintenance of these roads is neglected because of paucity of funds and the road asset created is in deteriorated condition. The non-availability of suitable soil and aggregates have made projects unviable and cost prohibitive. This aggregate scarcity will increase further as part of environmental conservation and restriction on mining. The stabilization of soil/aggregate is being used worldwide towards optimal usage of scares resources. The concept of cement treated base is included in IRC:37-2018 guidelines. The concepts of soil/aggregate stabilization and cold in place recycling technique provides a comprehensive solution for rehabilitation of existing road and green field road construction. Cold In Place Recycling process allow usage of locally available marginal materials. The stabilization process can use a wide range of stabilization agents such as soil-aggregate mix, lime, cement, fly ash, foamed bitumen, emulsion, polymers and other proprietary chemical stabilisers. Three rural roads are identified in Pune district. Pavements are designed considering cement treated base. The pavement cross section is analysed using IITPave and Street Pave software. These roads are constructed using cold in place recycling technique. The existing WBM/deteriorated bituminous surface is stabilised with cement. Bituminous concrete and Thin White Topping is provided as wearing course. The performance of pavement is evaluated after construction. The paper describes construction aspect, analysis and design, difficulties encountered and remedial measures suggested on three different case studies under consideration. The stabilised pavements offer superior strength and longevity, even in extreme climatic conditions and provide better performance. It is recommended to use cement treated base with cold in place technology for construction of rural roads.]]></description>

      <title>Estimation of Gradation and Contact Points in Asphalt Mixtures Using Image-Based Methods</title>
      <link>https://trid.trb.org/View/2652202</link>
      <description><![CDATA[Rutting is one of the major distresses asphalt mixtures undergo during the service life. Rutting is mainly considered as a shear failure, which is significantly influenced by the aggregate gradation. In this regard, determining aggregate gradation from the asphalt mixtures during various stages of the construction forms an important task in quality control and assurance plan. However, the current method of determining aggregate gradation uses toxic chemicals such as Trichloroethylene (TCE), which has shown to affect the health of workers in the long-run. This study adopted an approach to predict the gradation and also the contact points in different gradations for commonly used asphalt mixtures in India. Further, the contact points were correlated with rutting tolerance index determined from Ideal Rutting Test (IRT).The gradation was predicted using circle fitting algorithm, while the contact points were determined based on Surface Distance Threshold (SDT) approach. The results indicated that Dense Bituminous Macadam (DBM) gradation prediction showed the lowest error compared to Stone Matrix asphalt (SMA) and Open Graded Friction Course (OGFC). Meanwhile, SMA gradation depicted the highest number of contact points and this was also influenced by the compaction method adopted. A correlation of 70.35% was observed between the contact points and rutting tolerance index. Although image analysis was able to predict gradation and contact points with certain accuracy, results are influenced by several factors such as image acquisition and specimen preparation, which needs to be further explored.]]></description>

      <title>Optimizing the Planning of Precast Concrete Bridge Construction Methods to Maximize Durability, Safety, and Sustainability</title>
      <link>https://trid.trb.org/View/2673673</link>
      <description><![CDATA[The main goal of this project is to provide DOT planners with much-needed support that enables them to analyze and compare the performance of alternative bridge construction methods during the early design phase and optimize their construction decisions during the preconstruction phase. To accomplish this goal, the main tasks of this project focused on: (a) developing novel machine learning models to accurately predict the condition ratings of conventional cast-in-place and precast concrete deck bridges using National Bridge Inventory (NBI) data; (b) creating a practical decision support tool (DST) to analyze and compare the safety, mobility, sustainability, durability, and construction cost of alternative bridge construction methods during the early design phase; and (c) developing an original muti-objective optimization model for the planning of precast bridge projects to maximize their safety, mobility, and sustainability while minimizing their total construction cost during the preconstruction phase. The developed models and tools enable state DOTs and local agencies to accurately predict deck condition ratings for conventional and precast bridges; select the most suitable construction method for each planned project based on its specific requirements and constraints; and optimize the planning of precast bridge projects to achieve multiple objectives including maximizing safety, mobility, and sustainability while minimizing total construction cost.]]></description>

      <title>Dissimilar Ti Alloys Welding for the Automotive and Aviation Sector</title>
      <link>https://trid.trb.org/View/2665624</link>
      <description><![CDATA[Titanium alloys have an excellent strength-to-weight ratio. Tit alloys are almost as strong as steel but are much lighter. This translates into reduced mass in means of transportation (e.g., aircraft, F1 cars, electric vehicles, and motorcycles), which translates into better fuel efficiency, speed. Titanium can withstand very high temperatures without losing its mechanical properties. As a result, it has found applications in exhaust systems, hydraulic lines, fuel systems, and structural elements exposed to extreme conditions. In the construction of means of transport, two types of titanium with different structures are mainly used (alpha titanium and alpha + beta titanium). There will certainly soon be a need to weld these two dissimilar materials together. This is a research gap. An absolute novelty is the attempt to weld dissimilar titanium alloys without using a protective vacuum chamber. The purpose of this article is to establish the correct parameters for this process.]]></description>

      <title>Experimental Evaluation of Pre-Cast Pre-Stressed Segmental Concrete Bridge Columns</title>
      <link>https://trid.trb.org/View/2235282</link>
      <description><![CDATA[Segmental bridge column construction has been proven to be an economic and durable option to accelerate the bridge construction in non-seismic regions in the United States. Examples include Seven Mile Bridge in Florida and Chesapeake and Delaware (C&D) Canal Bridge in Delaware. The lack of knowledge of the seismic behavior of a bridge with segmental columns is one of the important reasons which limit the use of such kind of system in seismic regions. To promote the use of segmental bridge columns into seismic regions, four large scale segmental columns were constructed and tested at National Center for Research on Earthquake Engineering (NCEER) in Taiwan. Recently, some researches on seismic behavior of precast segmental columns have been carried out worldwide. Some studies emphasized the use of bonded tendons to enhance the durability and strength of the column as opposed to unbonded systems. Relevant studies can be found in Mo et al. and Arai et al. In addition to the bonded systems, some other researchers advocated the use of unbonded tendons to reduce the possibility of the yielding of the tendons, thus preserving the necessary clamping force after strong seismic event. Relevant studies can be found in Hewes et al., Chou et al., Billington et al., and Lee et al. The first column specimen tested in NCREE used unbonded post-tensioned tendons and no supplemental energy dissipation devices were provided. The other three specimens used bonded tendons and were provided with mild steel reinforcements that were extended across the joints to enhance the hysteretic energy dissipation.]]></description>

      <title>Static and fatigue behavior of novel UHPC wet joint connections for prefabricated composite bridge deck system</title>
      <link>https://trid.trb.org/View/2673004</link>
      <description><![CDATA[This paper aims to experimentally investigate the static and fatigue flexural performance of coarse aggregate ultra-high-performance concrete (UHPC) wet joints using mechanical sleeves based on the Ningchu Expressway Project, a 3 × 35 m steel-UHPC composite bridge in China. Eight static specimens comprising casting-in-place, and longitudinal and transverse wet joint specimens, were tested under negative moments and analyzed on their load-deflection responses, strain development, and cracking behavior. The test results showed that the peak load of wet joints was below 7% lower than that of casting-in-place. The cracking strength of the wet joint specimens with S-bars and U-bars reached 55.6% and 65.7% of the casting-in-place specimens. Steam curing could increase cracking loads and ductility by more than 10% than the natural curing method, satisfying the requirements of the engineering project. The fatigue test was conducted following the load specified by the Ningchu Expressway Project. After two million cycles, the maximum crack width was 0.19 mm, and the residual strength was still maintained by 95%. These findings indicate that the proposed UHPC wet joint with mechanical sleeve connections has excellent service performance and achieves uniform and efficient load transfer of steel bars in the UHPC wet joints, as well as accelerating construction efficiency and saving labor.]]></description>

      <title>Review of a Grievance Redressal Mechanism from Design and Implementation Perspective with
Special Reference to ‘Meri Sadak’ Under Pradhan Mantri Gram Sadak Yojana (PMGSY)</title>
      <link>https://trid.trb.org/View/2652197</link>
      <description><![CDATA[Receiving citizen's feedback and Grievance redressal plays a vital role in ensuring transparency, accountability, quality of road construction and maintenance and ultimately proper utilisation of the funds through citizens participation. Effective Grievance Redressal Mechanism (GRM) is a prerequisite of various funding agencies like World Bank, Asian Development Bank (ADB), the National and State Governments. Though the World Bank has published several documents on designing and implementing GRMs in infrastructure projects or ADB has done research on designing and implementing GRMs in road projects or some academic studies are published on GRM, most of the studies are discussing theoretical concepts without actual data analysis from design and implementation perspective. This study aims at overcoming this lacuna and thus providing a practical approach in designing and implementing a GRM by analysing annual data as obtained for the Maharashtra state from 'Meri Sadak', which is a mobile application developed by National Rural Infrastructure Development Agency (NRIDA), for registering feedback addressing the grievances regarding rural roads constructed under Pradhan Mantri Gram Sadak Yojana (PMGSY), a flagship program of the Government of India aimed at providing all-weather road connectivity to rural habitations.]]></description>

      <title>Construction of Extra Dose Bridge Across Mahi River in the Rajasthan State – Case Study</title>
      <link>https://trid.trb.org/View/2652196</link>
      <description><![CDATA[Rural India is experiencing sustained growth, with the rural economy outperforming urban growth and contributing significantly to India's overall economic expansion. With the demand of developing infrastructure and traffic intensity it is always demanded to construct the new route which reduces the travel distance and can enhance all side development for local as well as global surroundings. Due to construction of Dam on Mahi River in state of Gujarat named as Kadana constructed in years between 1979 and 1989, the connectivity between two district of Rajasthan state i.e. Dungarpur and Banswara have been ceased. This largely impacts the life of local inhabitants from their economic and social point of view. After a long running demand the Government of Rajasthan decided to construct a bridge at this location to facilitate the road users. The location where the bridge was proposed has very tough working conditions like having a standing water depth of around 25-30 meter.]]></description>

      <title>Lean Construction and the Digital Transformation of the AEC Industry: Towards Efficient, Sustainable and Resilient Infrastructure</title>
      <link>https://trid.trb.org/View/2652195</link>
      <description><![CDATA[The Architecture, Engineering, and Construction (AEC) industry is experiencing a fundamental transformation driven by two powerful movements Lean Construction and digital innovation. Together, these forces are redefining how infrastructure is conceived, designed, and delivered. Lean Construction represents a paradigm shift from the traditional project-centric approach to a production-based management philosophy that focuses on delivering maximum client value while systematically eliminating waste. Simultaneously, digital technologies such as Building Information Modeling (BIM), Digital Twins, the Internet of Things (IoT) and robotics have become enablers of Lean transformation. This fusion often termed Lean Construction 4.0 is revolutionizing the AEC industry by integrating collaborative planning, real-time data, and continuous feedback loops. For India, particularly in the public works sector, the convergence of Lean and digital technologies offers a path to more efficient, sustainable, and resilient infrastructure delivery. This paper examines the philosophy, tools, and ecosystem of Lean Construction, its integration with emerging digital technologies and its implications for transforming the AEC industry and public sector project management.]]></description>

      <title>Thermoplastic Composites by 3D Printing and Automated Manufacturing to Extend the Life of Transportation Facilities</title>
      <link>https://trid.trb.org/View/2672993</link>
      <description><![CDATA[Large-scale thermoplastic polymer extrusion-based additive manufacturing (AM) has been used to fabricate precast concrete formworks. There are some limitations inherent to the large-scale AM process that need to be overcome to design complex, multipart additively manufactured formworks to be used for precast concrete. This research work uses a large-scale polymer composite AM process to manufacture two-part formworks. Postprocessing was used to repair imperfections, create smooth casting surfaces, achieve precise dimensional tolerance, and incorporate assembly mechanisms for multipart formwork. Two biodegradable polymer composites (wood-fiber polylactic acid and wood-fiber amorphous polylactic acid) and a conventional polymer composite (carbon fiber acrylonitrile butadiene styrene) were selected to manufacture four sets of two-part formwork. Design details, including the cellular infill pattern, continuous toolpath, and layer time selection, are presented. Postprocessing and repairs performed on the manufactured formworks to get the required dimensional tolerance and surface smoothness are discussed.]]></description>
