农村公路沥青路面预防性养护措施研究进展

Research Progress on Preventive Maintenance Measures for Asphalt Pavement on Rural Roads

摘要:

农村公路作为连接城乡的重要基础设施，其沥青路面在长期使用过程中容易出现裂缝、车辙、松散等病害，使道路使用性能和行车安全受到影响。概述近年来关于农村公路沥青路面预防性养护措施的研究进展，通过对比预防性养护与传统养护的差异，深入阐述诸如裂缝填封、雾封层、碎石封层、微表处及薄层罩面等一系列常见的预防性养护技术手段，分析不同技术的适用条件和优缺点，并探讨了预防性养护在延长路面使用寿命、降低养护成本方面的优势。未来随着检测技术、决策方法和养护材料的不断进步，需要进一步加强技术创新和经验积累，以实现农村公路养护管理的科学化、精细化和智能化，为农村交通的可持续发展提供保障。

Abstract:

As an important infrastructure connecting urban and rural areas, the asphalt pavement of rural roads is prone to cracks, ruts, looseness and other diseases during long-term use, which affects the using performance and driving safety of the road. Aiming at the research progress on preventive maintenance measures for asphalt pavement on rural roads in recent years, by comparing the differences between the preventive maintenance and the traditional maintenance, a series of common preventive maintenance techniques such as crack sealing, fog sealing, gravel sealing, micro surfacing, and thin layer overlay are elaborated. The applicable conditions and advantages and disadvantages of different techniques are analyzed, and the advantages of preventive maintenance in extending the service life of pavement and reducing the maintenance costs are discussed. In the future, with the continuous advancement of detection technology, decision-making methods, and maintenance materials, it is necessary to further strengthen the technological innovation and experience accumulation to achieve the scientific, refined and intelligent management of rural road maintenance, and provide the continuous guarantee for the sustainable development of rural transportation.
