摘要
全断面铺筑沥青混凝土是铁路路基防排水技术的重大举措。文章介绍了沥青混凝土的主要性能特点及其在国内外铁路工程中的应用情况,从力学适用性、防水抗渗性和界面安全性3个方面阐述了铁路基床表层铺筑沥青混凝土的关键技术和研究进展,提出了铁路全断面铺筑沥青混凝土机械化施工的合理化建议。
Paving asphalt concrete on whole subgrade section is a major technique measure for railway subgrade waterproofing and drainage.T his paper introduced the main characteristics of asphalt concrete and its application in railway engineering at home and abroad.From three aspects of mechanical applicability,waterproof impermeability and interface security,the key technology of paving asphalt concrete on subgrade surface and its current research progress were expounded.Some rational suggestions on mechanical construction of paving asphalt concrete were put forward.
