Abstract

Bitumen emulsion cold mixing (BE-CM) technology is characterized by its environmental friendliness, resource conservation, and ease of construction. It plays a significant leading role in addressing the sustainability challenges in the highway transportation sector and has become a research hotspot in recent years. However, due to the presence of emulsifiers and moisture, the ionic environment of the solution components is complex. Currently, the moisture migration patterns within BE-CM mixtures and its effects on the micro-interface and macro-performance of BE-CM mixtures remain insufficiently understood. This has limited the widespread application of BE-CM technology. To further promote the development of BE-CM technology, this paper, based on bibliometric analysis, reviews and discusses the following three aspects: multi-scale characterization and modeling of moisture effects, adsorption and adhesion behavior at the bitumen emulsion-aggregate interface, and macroscopic performance enhancement of BE-CM mixtures. Additionally, several recommendations are provided to guide future research.

用于可持续路面的沥青乳液冷拌中的微界面动力学和宏观性能改进：对水分影响的批判性审查

沥青乳液冷拌（BE-CM）技术具有环境友好、节约资源和易于施工的特点。它在应对公路交通领域的可持续发展挑战方面发挥着重要的主导作用，近年来已成为研究热点。然而，由于乳化剂和水分的存在，溶液成分的离子环境十分复杂。目前，人们对 BE-CM 混合物中的水分迁移模式及其对 BE-CM 混合物的微观界面和宏观性能的影响仍然了解不足。这限制了 BE-CM 技术的广泛应用。为了进一步推动 BE-CM 技术的发展，本文在文献计量分析的基础上，对以下三个方面进行了回顾和讨论：水分效应的多尺度表征和建模、沥青乳液-集料界面的吸附和粘附行为以及 BE-CM 混合物的宏观性能提升。此外，还提出了一些指导未来研究的建议。
