Particulate matter (PM) in outdoor air pollution is one of the most critical factors that cause serious health problems and even deaths. One significant source of these particles are non-exhaust emissions, which refer to pollutants that come from sources, like brake, tire, and road wear other than a vehicle's exhaust system. This review focuses on the presence of non-exhaust particles on pavement, encompassing their classification, composition, evaluation, and mitigation. Based on extensive literature, it can be concluded that the quantity of non-exhaust emissions is affected by a combination of complex factors, such as vehicle speed, tire type, and pavement material. Non-exhaust particles can be classified into organic, inorganic, and metal matter, each requiring a distinct analysis and detection method. The effective approaches to managing non-exhaust emissions include water cleaning, utilizing functional pavement materials, and applying chemical reagents to alleviate emission capacity. Finally, this review recommends future research directions such as combining tire-road simulation with environmental monitoring equipment, in the hope that this article will have a positive impact on the mitigation of non-exhaust emissions.

Polyurethane (PU) as an alternative for petroleum asphalt binder in pavement engineering can not only prolong the service life of the pavement, but also enable the pavement to perform multiple functions such as drainage, noise reduction, snow melting, and ice melting, and flame retardancy, providing with economic, social and environmental benefits. PU is a kind of "wear-resistant rubber" with high strength and good wear resistance obtained by pre-polymerization of isocyanate and polyol. In this review, the design and preparation of PU and aggregates, i.e., PU mixture, were summarized, followed by the discussion of the strength, stiffness and durability of PU mixture. Numerous creative concepts of structure and mixture design of PU pavements were summarized, and PU dosage, the curing time, temperature, and compaction times were clarified in detail. Particularly, some successful applications including poroelastic road surface (PERS), PU porous mixture (PPM), PU rubber particle mixture (PRPM), and permeable PU stabilized recycled aggregate (PPSRA) were discussed. Special attention was given to the economic and environmental benefits of PU pavement. Overall, the PU pavement can achieve the much-needed functions of modern urban roads or highways, and prolong the service life of the pavement. However, more researches are needed to explore the design methods of PU mixture and improved its road performance. In addition, reducing the price of PU to reduce the construction cost of PU mixture was also a problem that needed to be solved.

Road networks are the backbone of urban life and significantly impact the sustainability of any country's infrastructure sector. Therefore, it is necessary to maintain the condition of roads and pavements through continuous monitoring and periodic maintenance in order to achieve the highest levels of service for road users and the sustainability of their use. Pavement is the main component of road networks, providing the highest degree of comfort to drivers and roadway users when it is appropriately designed and free from defects and cracks. More clearly, defects are one of the most important factors that reduce the operational life of roads and cause economic losses to road users by causing damage to their vehicles; moreover, the damaged pavement needs frequent and long maintenance that may also drain the resources of government institutions and transport agencies. Therefore, there is a crucial need for a monitoring and follow-up system for the condition of the roads in order to identify and treat defects quickly. This study used a vibration-based system to monitor pavement conditions on several roads with different gradients. A fully electric car was used to determine the vibration values, which indicate the degree of driving comfort, to determine the spread and behaviour of defects on the pavement at multiple locations on roads with different gradients. Also, a machine learning model was applied using a “decision tree” model to identify, classify and predict defects on the pavements. The results of this study indicated that pavement defects were more prevalent in the first and last quadrants of the high-slope roads compared to the low-slope roads. The prediction model achieved accuracy in predicting the performance of defects with a rate of 94% for roads with low gradients and 90% and 86% for roads with medium and high gradients, respectively.

In recent years, research on the state of health (SOH) and remaining useful life (RUL) estimation methods for lithium-ion batteries has garnered significant attention in the new energy sector. Despite the substantial volume of annual publications, a systematic approach to quantifying and analyzing these contributions is lacking. This study focuses on selecting pertinent literature related to lithium-ion battery SOH and RUL estimation from CNKI and WOS databases, spanning January 2010 to December 2023. Employing bibliometric tools such as VOSviewer and CiteSpace, we conduct visual analyses to elucidate the current state, development trends, and research frontiers in this domain. Our examination encompasses scholarly activity, year-wise literature distribution, international collaboration networks, structural dissemination, and journal contributions. The findings indicate an upward trend in annual publication output, with China, the United States, the United Kingdom, and Canada at the forefront of collaborative research efforts. China is increasingly recognized as a pivotal hub for global scholarly partnerships. Notably, Harbin Institute of Technology, Beijing Institute of Technology, Chongqing University, Chinese Academy of Sciences, and Beijing Jiaotong University are the top institutions in China and the world in terms of publications. The Journal of Energy Storage emerges as a prominent periodical, acclaimed both domestically and internationally for its rigorous standards and high-quality articles. Based on the research content from CNKI and WOS, VOSviewer clusters the main research directions into three themes: aging mechanisms, SOH estimation methods, and RUL prediction methods. Keywords such as ‘online estimation’, ‘hybrid models’, and ‘artificial neural networks’ feature prominently, signaling a strong emphasis on artificial intelligence strategies. The study concludes with a prospective outlook on imminent research trajectories regarding the health and longevity estimations of lithium-ion batteries, highlighting the critical need for ongoing innovation and collaboration in this essential field.

Elevated pavement temperatures contribute to the urban heat island effect and pose a risk of thermal damage to pavement. Thus, regulating pavement temperature is paramount to ensure its longevity, enhance traffic safety, and preserve the environment. Phase change materials (PCMs) with the latent heat characteristic can store and release thermal energy via phase transitions. PCMs can effectively control pavement structure temperatures within a relatively narrow range, mitigating thermal stress on asphalt pavements. This research aims to explore the current status and emerging trends in PCM integrated pavement engineering (PCMIPE) using the CiteSpace visual analysis tool. Relevant publications were systematically curated from the Web of Science core database, spanning 2011 to 2023. Subsequently, the co-authorships network maps (country, institution, author), co-cited network maps (co-cited journals, authors, and references), and keyword co-occurrence network maps were constructed to analyze the principal contributions in the PCMIPE field comprehensively. This analysis provides an understanding of the field's strengths, research domains, and knowledge structure and identifies current research focal points and emerging frontiers. The findings reveal that research within the PCMIPE field is still in its early stages, with a predominant emphasis on material design and performance assessment. Additionally, future research is anticipated to expand into economic analyses and exploration of environmental effects when integrating PCMs into pavement engineering. Furthermore, there is an emerging interest in investigating the synergy of PCMs with other functional pavement technologies. These results underscore the potential of the PCMIPE field and emphasize the importance of future research endeavors.

The years we are experiencing are often identified as those of the age of digital technologies, where “digital” is commonly associated with intelligence, efficiency, and convenience. The emergence of digital technologies has significantly impacted and transformed various aspects of our society compared to the past. In this panorama, some arising questions regard transportation infrastructure systems and, first of all, highway infrastructure. This research focuses on one central issue: how highways fit into this digital revolution. Actually, the work in this paper can be described as follows. Although there are many different theoretical model systems for the architecture of the digital twin, we have chosen to review the main body of research on the digital twin in highway infrastructure based on a relatively well-established modeling framework, the five-dimensional model of the digital twin. After discussing the components of the digital twin for highway infrastructure's five-dimensional model, the paper reviews some innovative technologies that make these items effective.

Cold milling is a widely used method for rehabilitating asphalt pavement, generating reclaimed asphalt pavement (RAP) chunks. Within this process, aggregates within the asphalt pavement will be crushed, forming RAP agglomerates and aggregate breakdown. However, the mechanism of these phenomena has remained unclear, and a unified evaluation method has yet to be established. In this study, RAP agglomeration and aggregate fragmentation were characterized, five distinct methods were systematically assessed, and the mechanism of RAP agglomeration and breakdown was analyzed by discrete element method (DEM) simulation based on setting different particle contact parameters, then followed by a mechanical analysis, and demonstrated in engineering. The results revealed that both agglomeration and aggregate breakdown occur within RAP particles of various sizes, with the five methods showing similar trends in quantifying these effects. Through DEM simulations and mechanical analyses, the aggregate breakdown predominantly occurs at the cutter's motion trajectory of the cutter and during crack propagation, while agglomeration was mainly related to the sliding surface's area. The milling speed and depth positively impact RAP agglomeration, while negatively affecting aggregate breakdown, and milling drum speed exerts minimal influence on these phenomena. RAP agglomeration varies considerably in different engineering projects, and cold milling parameters should be determined based on the material composition of the asphalt pavement and design requirements to control agglomeration and breakdown rates of RAP.

冷铣刨机是一种广泛使用的修复沥青路面的方法，可产生再生沥青路面（RAP）大块。在此过程中，沥青路面中的集料会被压碎，形成 RAP 团块和集料破碎。然而，这些现象的机理尚不清楚，统一的评估方法也尚未建立。本研究对 RAP 结团和集料破碎进行了表征，系统地评估了五种不同的方法，并在设置不同颗粒接触参数的基础上，通过离散元法（DEM）模拟分析了 RAP 结团和集料破碎的机理，然后进行了力学分析，并在工程中进行了演示。结果表明，在不同大小的 RAP 颗粒中都会发生团聚和聚合破裂，五种方法在量化这些效应方面表现出相似的趋势。通过 DEM 模拟和力学分析，骨料破碎主要发生在铣刀的运动轨迹和裂纹扩展过程中，而聚结主要与滑动面的面积有关。铣削速度和深度对 RAP 结块产生积极影响，而对骨料破碎产生消极影响，铣削滚筒速度对这些现象的影响很小。在不同的工程项目中，RAP 的结块情况差异很大，应根据沥青路面的材料组成和设计要求确定冷铣刨机参数，以控制 RAP 的结块和破碎率。

Waste plastics and rubber have always posed a threat to the environment and a great challenge for disposal. The use of these two waste materials as modifiers for road asphalt provides new road asphalt binders and at the same time provides a new way for waste material resource treatment. Rubber-modified asphalt and plastic-modified asphalt have received widespread attention due to their green and low-carbon characteristics and some performance advantages, but there are still some performance shortcomings that hinder their promotion and application. In order to continue to explore the application of waste materials in the field of road engineering, combined with the performance advantages of both, many scholars began to study the rubber-plastic composite modified asphalt (RPCMA). Therefore, this paper reviewed the different types of waste rubber and plastic, the comprehensive performance of different types of asphalt and its mixture performance, analyzed the modification mechanism of rubber-plastic composite modified asphalt and its performance changes. The results show that rubber-plastic composite modified asphalt is mostly prepared by directly adding modified materials. However, the pretreatment or melt granulation of rubber and plastic will make the performance of rubber-plastic modified asphalt has improved. There is a mutual promotion mechanism between rubber and plastic in asphalt, which makes the performance of rubber-plastic modified asphalt better than that of asphalt obtained by a single modification method (rubber modified asphalt or plastic modified asphalt). In some properties, it can be close to the commercial SBS modified asphalt. The performance of rubber and plastic composite modified asphalt at high temperature has been generally recognized by researchers, but its low-temperature performance is still controversial. Therefore, it is recommended to apply in high-temperature areas. Future work should focus on the development of composite modifiers with stable performance, low cost and ease of use, standardization of modification processes, improvement of low-temperature performance, and monitoring of road performance and environmental impact.

废塑料和废橡胶一直对环境构成威胁，也是处理过程中的巨大挑战。利用这两种废旧材料作为道路沥青改性剂，在提供新型道路沥青胶结料的同时，也为废旧材料资源化处理提供了一条新途径。橡胶改性沥青和塑料改性沥青因其绿色低碳的特点和一定的性能优势受到广泛关注，但仍存在一些性能缺陷，阻碍了其推广应用。为了继续探索废旧材料在道路工程领域的应用，结合二者的性能优势，许多学者开始研究橡胶塑料复合改性沥青（RPCMA）。为此，本文综述了不同类型废旧橡塑、不同类型沥青的综合性能及其混合料性能，分析了橡塑复合改性沥青的改性机理及其性能变化。结果表明，橡塑复合改性沥青多采用直接添加改性材料的方法制备。但橡塑预处理或熔融造粒会使橡塑改性沥青的性能得到改善。橡胶和塑料在沥青中存在相互促进的机理，使得橡塑改性沥青的性能优于单一改性方法（橡胶改性沥青或塑料改性沥青）制备的沥青。在某些性能上，它可以接近商品 SBS 改性沥青。橡塑复合改性沥青的高温性能已得到研究人员的普遍认可，但其低温性能仍存在争议。因此，建议在高温地区应用。今后的工作重点应放在开发性能稳定、成本低廉、使用方便的复合改性剂，规范改性工艺，提高低温性能，监测道路性能和环境影响等方面。
