Abstract

Under the background of pavement engineering driving towards sustainability and resilience, there is an urgent need for high performance and eco friendly asphalt materials. Montmorillonite (MMT) modified asphalt composites arise as a groundbreaking solution, offering integrated advantages in mechanical reinforcement, aging resistance, and environmental decontamination. By utilizing MMT, a natural layered silicate, as a green nano modifier, these composites present a sustainable alternative to conventional polymer modified asphalt, significantly reducing petroleum based additive consumption while enhancing thermal stability and flame retardancy. The unique nanostructure, characterized by exfoliated silicate layers with tunable interlayer space and high specific surface area, enables exceptional oxygen/UV shielding and VOCs adsorption capacities. This review comprehensively examines the fundamental mechanisms governing MMT asphalt interactions, focusing on the synergistic effects of intercalation induced rheological enhancement, tortuous oxygen diffusion pathways, and catalytic pollutant degradation. Key challenges, including low temperature performance trade-offs and incomplete nanolayer exfoliation, are addressed through advanced modification strategies. In addition, given MMT's significant intrinsic physicochemical variability, clarifying the influence of these fundamental properties on asphalt performance is paramount. The review further discusses the scalable fabrication protocols and machine learning assisted performance prediction models to bridge laboratory innovations with engineering practice. This review aims to offer valuable insights for researchers and engineers working in the fields of green and high performance asphalt pavement construction.

蒙脱石-沥青复合材料的系统综述：绿色粘土矿物-增强沥青可持续路面解决方案

在路面工程向可持续性和弹性方向发展的背景下，迫切需要高性能、环保的沥青材料。蒙脱土（MMT）改性沥青复合材料作为一种开创性的解决方案，在机械加固、抗老化和环境净化方面具有综合优势。通过使用天然层状硅酸盐MMT作为绿色纳米改性剂，这些复合材料提供了传统聚合物改性沥青的可持续替代品，显著减少了石油基添加剂的消耗，同时提高了热稳定性和阻燃性。独特的纳米结构，其特点是脱落的硅酸盐层具有可调的层间空间和高比表面积，具有卓越的氧气/紫外线屏蔽和挥发性有机化合物吸附能力。这篇综述全面探讨了控制MMT沥青相互作用的基本机制，重点是插层诱导的流变增强、扭曲的氧扩散途径和催化污染物降解的协同效应。关键的挑战，包括低温性能的权衡和不完全的纳米层剥离，通过先进的改性策略来解决。此外，考虑到MMT具有显著的内在物理化学变异性，阐明这些基本性质对沥青性能的影响至关重要。本文进一步讨论了可扩展的制造协议和机器学习辅助性能预测模型，以将实验室创新与工程实践相结合。本文旨在为绿色高性能沥青路面施工领域的研究人员和工程师提供有价值的见解。
