The application of superhydrophobic (SH) coatings in road construction has attracted growing attention due to their potential to improve surface durability, reduce cracking, and enhance skid resistance. Among various materials, SiO nanoparticles have emerged as key components in SH coatings by contributing essential surface roughness and hydrophobicity. This review paper analyzes the role of SiO nanoparticles in enhancing the water-repellent properties of coatings applied to road surfaces, particularly concrete and asphalt. Emphasis is placed on their influence on road longevity, reduced maintenance, and overall performance under adverse weather conditions. Furthermore, this review compares functionalization techniques for SiO using different hydrophobic modifiers, evaluating their efficiency, cost effectiveness, and scalability for large-scale infrastructure. In addition to highlighting recent advancements, this study discusses persistent challenges-including environmental compatibility, mechanical wear, and long-term durability-that must be addressed for practical implementation. By offering a critical assessment of current approaches and future prospects, this short review aims to guide the development of robust, high-performance SH coatings for sustainable road construction.
超疏水（SH）涂层在道路建设中的应用因其具有改善表面耐久性、减少裂缝和增强防滑性的潜力而受到越来越多的关注。在各种材料中，SiO纳米颗粒已成为SH涂层的关键成分，它能提供必要的表面粗糙度和疏水性。这篇综述文章分析了SiO纳米颗粒在增强应用于路面（特别是混凝土和沥青路面）的涂层的防水性能方面所起的作用。重点关注它们对道路使用寿命、减少维护以及在恶劣天气条件下的整体性能的影响。此外，本综述比较了使用不同疏水改性剂对SiO进行功能化的技术，评估了它们的效率、成本效益以及大规模基础设施应用的可扩展性。除了突出近期的进展外，本研究还讨论了实际应用中必须解决的持续挑战，包括环境兼容性、机械磨损和长期耐久性。通过对当前方法和未来前景进行批判性评估，这篇简短的综述旨在指导开发用于可持续道路建设的坚固、高性能的SH涂层。
