摘　　要：沥青混凝土防水封闭层作为一种新型高速铁路路基防水封闭层,近年来得到铁路工程界的广泛关注。本文简要介绍了沥青混凝土防水封闭层在国内外的研究与应用情况,总结了沥青混凝土防水封闭层的技术特点和优势。结合我国高速铁路特点及运维需求,提出了全断面式和自密实型2种沥青混凝土防水封闭层技术方案,并对其技术特点、适用范围、防水效果、技术性能等进行了综述。In recent years,asphalt concrete waterproof sealing layer,as a new type of high speed railway subgrade waterproof sealing layer,has received widespread attention. Current research and application state of asphalt concrete waterproof sealing layer at home and abroad was introduced in this paper. The technical features and advantages of asphalt concrete waterproof sealing layer were summarized. Combining with Chinese high speed railway characteristics and operation and maintenance requirements,two types of asphalt concrete waterproof sealing layer technology schemes were put forward. Those are full section type and self-compacting type. Their technical features,application scope,waterproofing effect and technical performance were summarized.
