Special Issue Information

Dear Colleagues,

Urban infrastructure construction and management, as the backbone of urban economic and social development, have significant impacts on green economic development. However, with the growing demands of urbanisation, population growth, and climate change, urban infrastructure will undoubtedly face more serious challenges. In order to solve these challenges, new construction materials and technologies are needed to enhance and improve urban infrastructure construction, such as roads, bridges, and so on. For example, urban road infrastructure is currently encountering severe obstacles, such as higher and lower temperatures, flooding, and an increased number of freezing and thawing cycles due to climate change. To avoid more frequent pavement maintenance, rehabilitation, and reconstruction, researchers and transportation agencies have recently started to focus on the resilience of pavement structures and materials. In addition, there is significant potential for improvement through the digitalisation of processes and the application of the building information modelling (BIM) approach, a methodology used to improve efficiency in urban infrastructure construction. Meanwhile, utilizing artificial intelligence and machine learning for urban infrastructure construction and management is conducive to enhancing the integration of roadside infrastructure and intelligent transportation systems. This approach shows promise in improving traffic safety and system management efficiency. The construction and management of infrastructure pose various environmental risks that jeopardize the well-being of urban inhabitants and construction workers. It is imperative to employ scientific modelling techniques to accurately assess these environmental impacts throughout the entire life cycle.

This Special Issue “Urban Infrastructure Construction and Management” will provide an overview of existing knowledge on new materials, processes, and technologies for urban infrastructure construction. Original research, theoretical and experimental work, case studies, and comprehensive review papers are invited for possible publication.

Relevant topics to this Special Issue include (but are not limited to) the following subjects:

  • New materials for urban infrastructure construction;
  • Advanced technologies for infrastructure construction;
  • Sustainable infrastructure construction management;
  • Infrastructure construction structural health monitoring;
  • Machine-learning-powered management;
  • Urban infrastructure construction under climate change;
  • Smart and sustainable infrastructural construction;
  • Building information modelling (BIM) for infrastructural construction;
  • Environmental impact modelling for infrastructure in the life cycle.

Pavement distress seriously affects the quality of pavement and reduces driving comfort and safety. The dropped objects from vehicles have increased the risks of traffic accidents. Therefore, automatic detection of urban pavement distress and dropped objects is an effective method to timely evaluate pavement condition. Firstly, this paper utilized a portable platform to collect pavement distress and dropped objects to establish a high-quality dataset. Six types of pavement distresses: transverse crack, longitudinal crack, alligator crack, oblique crack, potholes, and repair, and three types of dropped objects: plastic bottle, metal bottle, and tetra pak were included in this comprehensive dataset. Secondly, the real-time YOLO series detection models were used to classify and localize the pavement distresses and dropped objects. In addition, segmentation models W-segnet, U-Net, and SegNet were utilized to achieve pixel-level detection of pavement distress and dropped objects. The results show that YOLOv8 outperformed YOLOv5 and YOLOv7 with a MAP of 0.889. W-segnet showed an overall MIoU of 70.65% and 68.33% on the training set and test set, respectively, being superior to the comparison model and being able to achieve high-precision pixel-level segmentation. Finally, the trained models were performed on the holdout dataset for the generalization test. The proposed methods integrated the detection of urban pavement distress and dropped objects, which could significantly contribute to driving safety. Full article

Attapulgite-hydroxyethyl cellulose-poly (acrylic acid-co-2-acrylamide-2-methylpropanesulfonic acid) (ATP-HEC-P(AA-co-AMPS)) in-concrete curing material was synthesized by aqueous solution polymerization using attapulgite (ATP) as an inorganic filler and hydroxyethyl cellulose (HEC) as a backbone. The effects of relevant factors such as ATP dosage, HEC dosage, degree of neutralization, initiator quality, and cross-linking agent quality on the water absorption characteristics of ATP-HEC-P (AA-co-AMPS) were investigated through expansion tests. The micro-morphology of ATP-HEC-P (AA-co-AMPS) was also comprehensively characterized using Fourier transform infrared spectroscopy, scanning electron microscopy, a thermal analysis, and other applicable means. The results showed that the prepared ATP-HEC-P (AA-co-AMPS) had a strong water absorption and water retention capacity, with a water absorption multiplicity of 382 g/g in deionized water and 21.55% water retention capacity after being placed at room temperature for 7 d in a bare environment. Additionally, ATP-HEC-P (AA-co-AMPS) showed good performance for absorbing liquids within the pH range of 7–12. The material’s thermal stability and mechanical properties were also significantly improved after the addition of ATP. The preparation cost is low, the process is simple, and the material meets the requirements for concrete curing materials. Full article

In order to investigate the influence of igneous rock powder and silica fume on the performance of cement mortar, facilitate the application of igneous rock powder in engineering, and promote the greening of the cement industry, this study examined the pozzolanic activity of three different types of igneous rock powders: granite, andesite, and tuff. It explored the workability and mechanical properties of both binary systems (igneous rock–cement) and ternary systems (igneous rock–silica fume–cement). Microscopic techniques including X-ray diffraction (XRD), thermogravimetric analysis–differential thermal analysis (TG-DTA), scanning electron microscopy (SEM), and nitrogen adsorption were used to investigate the mechanisms of how different types of igneous rock and silica fume affect the cementitious systems. The results showed that the pozzolanic activity of igneous rock powders was relatively weak, and their inclusion at levels below 20% had minimal impact on the flowability of cement mortar. In fact, within the 20% inclusion range, andesite powder even increased the flowability. Co-blending igneous rock powders with silica fume promoted the early hydration of cement, resulting in reduced calcium hydroxide (CH) content in the hydration products. The most significant increase in strength of the cement mortar system was observed when 5% to 10% (by mass) of igneous rock powder and 5% to 10% of silica fume were used as replacements for cement. The highest cement mortar strength was achieved when 10% andesite and 10% silica fume were used as replacements, resulting in a compressive strength of 52.2 MPa. Full article

Recycling aluminosilicate-based solid wastes is imperative to realize the sustainable development of constructions. By using alkali activation technology, aluminosilicate-based solid wastes, such as furnace slag, fly ash, red mud, and most of the bio-ashes, can be turned into alternative binder materials to Portland cement to reduce the carbon footprint of the construction and maintenance activities of concrete structures. In this paper, the chemistry involved in the formation of alkali-activated materials (AAMs) and the influential factors of their properties are briefly reviewed. The commonly used methods, including X-ray diffraction (XRD), scanning electron microscopy (SEM), thermogravimetric analysis (TG), nuclear magnetic resonance spectroscopy (NMR), and X-ray pair distribution function technology, to characterize the microstructure of AAMs are introduced. Typical characterization results of AAMs are shown and the limitations of each method are discussed. The main challenges, such as shrinkage, creep, efflorescence, carbonation, alkali–silica reaction, and chloride ingress, to conquer for a wider application of AAMs are reviewed. It is shown that several performances of AAMs under certain circumstances seem to be less satisfactory than traditional portland cement systems. Existing strategies to improve these performances are reviewed, and recommendations for future studies are given. Full article
