Special Issue Information

Dear Colleagues,

The sustainability and high resilience of infrastructure are becoming increasingly important and, as a key component of infrastructure, asphalt pavements play a crucial role in achieving the goals of long service life and low-carbon recycling. With the wholescale construction of infrastructure and the advancement of construction technologies, many new technologies have emerged in the research and application of asphalt pavement materials and structures. The study of new technologies, such as functional modification, recycling, intelligent detection, numerical simulation, and low-carbon design, plays a crucial role in achieving the sustainable development of asphalt pavements. In this Special Issue, the latest applications of these technologies in asphalt pavements are discussed. The aim is to bring together cutting-edge research and applications, and to share and present innovative materials and technologies that promote the sustainable development of asphalt pavements. The topics cover, but are not limited to:

  • The functional modification of asphalt pavement materials;
  • Recycling and the utilization of solid waste materials;
  • Anti-skid detection and evaluation of asphalt pavements;
  • The numerical simulation of asphalt pavements;
  • The low-carbon design of asphalt pavement structures.

High Friction Surface Treatments (HFSTs) are frequently used to increase skid resistance and reduce collisions, particularly in crash-prone zones, including horizontal curves and intersections. Epoxy-based binders traditionally have been the sole option for HFSTs, but their drawbacks, such as high costs and compatibility challenges, have led to the search for substitute binders, including asphalt-based options. This study investigates the comparative performance of highly modified asphalt-based binders, including polymer-modified, mastic, and highly modified emulsions, in HFST applications using two aggregate types, Calcined Bauxite (CB) and Rhyolite with different gradations, with an emphasis on their frictional properties, durability, and resistance to polishing. Laboratory evaluations, including the Pendulum Tester (BPT), Dynamic Friction Testing Equipment (DFT), Surface Texture Measurement Apparatus (CTM), and Binder Bond Strength Test (BBS), were carried out to examine the Coefficient of Friction (COF), Mean Profile Depth (MPD), and aggregate bonding and retention. In terms of durability and friction, this study indicated that highly modified asphalt-based binders performed better than PG binders and conventional emulsions. The highest BPT values, both prior to and following polishing, were consistently observed for CB, with the emulsion containing the highest reactive polymer modifier showing the smallest decrease in BPT value (12.86% for CB and 10.34% for Rhyolite). Epoxy showed a greater COF retention over lengthy polishing cycles; however, highly polymer-modified (PM) binders like PG82-22 (PM) performed better than Epoxy under specific conditions. The macrotexture analysis revealed that Epoxy-based samples retained surface texture for further polishing cycles, while Mastic2 and PG82-22 (PM) also showed strong MPD retention. These findings highlight the importance of optimizing aggregate–binder combinations to ensure durable and effective HFST applications. Full article

Warm mix asphalt pavements can effectively reduce construction energy consumption and control environmental pollution compared to conventional asphalt pavements. However, there is no clear test standard for the evaluation of warm mix agents. The selection of a warm mix agent is easily influenced by subjective factors. Moreover, it is difficult to consider quantitative and qualitative factors such as technical indexes and the economy. A fuzzy hierarchical comprehensive evaluation model of warm mix agents is proposed based on fuzzy hierarchical analysis. Four types of indexes, namely, material properties, technical indexes, economy, and construction difficulty, were selected to construct the hierarchical structure of the target, guideline, and indicator layers. The influence weights of all factors were determined by the judgment matrix, and an affiliation judgment matrix was established at the same time. Finally, the comprehensive score of the warm mix agent modification effect was calculated. Three warm mix agents were selected for market research and indoor testing. And the evaluation model was applied to process the data. The calculation results show that the technical indicators have the greatest influence, with a weight proportion of 0.493; WM-2 had the best comprehensive evaluation, with a comprehensive score of 0.96, and its optimal mixing amount was 0.3%. The calculation results further verified the effectiveness of the fuzzy hierarchical comprehensive evaluation model of warm mix agents. Compared with the existing methods, the fuzzy-hierarchical-integrated evaluation model of warm mix agents has a more comprehensive evaluation scope, lower subjective factor bias, and more flexible application scenarios. It provides a more rigorous and convenient idea for the development and evaluation of different warm mix agents. In conclusion, the model has greater application value and popularization value.

The adhesion property has consistently been a critical focus in the utilization of recycled asphalt (RA). This research aimed to elucidate the mechanisms influencing the adhesion property of RA at various scales. Specimens of base asphalt (BA), aged asphalt (AA), and RA were systematically prepared. The impacts of aging and rejuvenators on the nano adhesion property of asphalt were assessed using multi-scale testing methods. The findings revealed that aging adversely affected the adhesive interaction between BA and aggregate, whereas the application of rejuvenators substantially improved this effect. When compared to acidic aggregate of granite, the alkaline aggregate of limestone demonstrated superior adhesion properties with RA. Moreover, the correlation analysis affirmed that mechanical testing across various scales consistently evaluated the trends in the adhesion property of RA with aggregates. Full article

This is a comprehensive review of the significance of solubility theories, internal stability, and external compatibility within petroleum science and pavement engineering. The historical development and future trends of solubility methods in bitumen are discussed, emphasizing the importance of separating bitumen components based on solubility to establish a link with chemistry. The paper also highlights the development of solubility theories and various characterization tests for bitumen, as well as the distribution of functional groups of solvents and their parameters. Additionally, it explores the generation of solubility profiles for different types and aging states of bitumen based on solubility data and statistical correlation, and the use of stability diagrams to assess the internal stability of bitumen in different states. The potential for continued research in this field is emphasized to bridge the gap between fundamental chemistry and practical application, leading to improved formulations and enhanced performance of bitumen in various applications, ultimately resulting in more durable and stable pavement structures.
