摘　　要：China has a large solid waste stockpile and a low resource utilisation rate,and the utilisation of solid waste resources is of great significance in promoting sustainable social development.In order to further promote the green and efficient development of China's road field,an overview of the current status of the application,research progress,hot frontiers,problems and their countermeasures based on the three aspects of industrial solid wastes,engineering solid wastes and municipal solid wastes in highway engineering was conducted,and the development prospect of the resourceful utilisation of solid waste in highway engineering was outlooked,with a view to promoting the development of China's green roads.Statistics on the stockpile,utilisation and comprehensive utilisation rate of industrial solid wastes in China are presented,and the optimal mixing amount,production process and application technology of industrial solid wastes for road base materials are systematically summarised.Based on the concept of high-value utilisation of solid waste,the mechanical properties,durability,construction technology and quality control standards of engineering solid waste applied in roadbed engineering are summarised,and the difficulties in the application of engineering solid waste in road engineering are summarised.Finally,the feasibility,mechanical properties and environmental characteristics of municipal solid waste domestic waste incinerator slag,waste tyres and plastics applied in road engineering are summarised.This review can provide references and lessons for the design and development of green roads,and promote the innovation and development of greening road engineering.我国固废存量大、资源化利用率低,固废资源化利用对促进社会可持续发展具有重要意义。为进一步推动我国公路领域的绿色高效发展,从工业固废、工程固废和城市固废三个方面综述了固废在公路工程中的应用现状、研究进展、热点前沿、存在问题及其对策,展望了固废资源化利用在公路工程中的发展前景,以期推动我国绿色公路的发展。统计了我国工业固体废弃物的堆存量、利用量和综合利用率,系统总结了路基材料工业固体废弃物的最佳掺量、生产工艺和应用技术。基于固体废弃物高值化利用的理念,总结了工程固体废弃物在路基工程中应用的力学性能、耐久性能、施工工艺和质量控制标准,归纳了工程固体废弃物在道路工程中应用的难点。最后,分析了城市固体废弃物生活垃圾焚烧炉炉渣、废轮胎和建筑垃圾在路基工程中应用的可行性、力学性能和环境特征。本综述可为绿色道路的设计与开发提供参考和借鉴,促进道路工程绿化的创新与发展。
