摘要:

湿法橡胶沥青作为一种环保型道路材料,契合了“减少(Reduce)、重复利用(Reuse)、回收(Recycle)”(3R)环保策略的理念。本文综述了湿法橡胶沥青在高温存储过程中可能面临的稳定性问题,特别是针对沥青与橡胶颗粒之间的密度差异所引发的挑战。首先,详细阐述了橡胶沥青的制备过程,强调了其采用废橡胶作为原料的环保性质,并指出了其对环境友好的重要意义;其次,深入探讨了湿法橡胶沥青在道路建设中的应用,并对比了其与传统沥青的性能以及存储性能的差异;随后,进一步探讨了如何通过改进生产工艺和优化存储条件来提高湿法橡胶沥青的稳定性,并提出了相关的解决方案和技术路径;最后,指出了当前研究中存在的挑战与机遇,并提出了未来深入探讨湿法橡胶沥青在3R环保策略下的应用前景的建议,为可持续发展和环境保护提供了新的思路和方法,为相关领域的研究和实践提供了有益的指导和借鉴。

Abstract:

As an eco⁃friendly pavement material, wet⁃process asphalt rubber (WPAR) aligns with the "Reduce, Reuse, Recycle" (3R) environmental strategy. This paper systematically reviewed stability challenges in WPAR during high⁃temperature storage, particularly those caused by density differences between asphalt and rubber particles. First, the preparation process of rubber asphalt was elaborated, emphasizing its environmental benefits through waste tire recycling and life⁃cycle advantages. Next, the performance characteristics and storage stability of WPAR were compared with conventional asphalt in road construction applications. The review then analyzes stability enhancement strategies through production process optimization and improved storage conditions, proposing technical solutions for industry implementation. Finally, current research gaps and future opportunities were identified, suggesting promising directions for WPAR development within the 3R framework. This work provides both theoretical guidance and practical references for sustainable pavement material research while offering novel approaches for environmental protection in transportation infrastructure.

Key words: wet asphalt rubber, storage stability, pavement performance, process optimization, environmental impact
