摘　　要：为探讨沥青碎石封层技术在公路养护中的应用,采用理论结合实践的方法,立足沥青碎石封层技术的原理,分析了此项技术在公路养护中的实际应用以及取得的效果。分析结果表明,公路养护具有很强的复杂性、技术性,传统粗放式的养护技术难以实现对公路的全方位养护,沥青碎石封层技术可在现有路面上铺设一层或多层沥青混合料,并撒布一定量的碎石骨料,形成具有防水、抗裂和防滑功能的封层,从而实现对公路的全面养护,提升公路安全使用寿命,具有良好的推广前景和应用价值。In order to explore the application of asphalt aggregate sealing technology in highway maintenance,this paper adopts a theoretical and practical method,based on the principle of asphalt aggregate sealing technology,and analyzes the practical application and effects of this technology in highway maintenance.The analysis results show that highway maintenance has strong complexity and technicality.Traditional extensive maintenance techniques are difficult to achieve comprehensive maintenance of highways.Asphalt crushed stone sealing technology can lay one or more layers of asphalt mixture on the existing road surface,and sprinkle a certain amount of crushed stone aggregate to form a sealing layer with waterproof,crack resistant and anti-skid functions,thereby achieving comprehensive maintenance of highways,improving the safe service life of highways,and has good promotion prospects and application value.
