长寿命沥青路面路用性能优良,在美国、欧洲、加拿大、澳大利亚、南非都有广泛的研究。长寿命路面的设计理念代表了当前高等级公路路面结构选择和设计的一个趋势。与我国现在普遍使用的半刚性基层路面相比长寿命沥青路面具有明显的优势。从长寿命沥青路面的基本概念和特点入手,阐述了长寿命沥青路面在结构设计方法以及路面结构施工、路面性能定期监测、磨耗层维护与更换等方面所采用的方法和应该注意的问题。
Long-life asphalt pavement with excellent performance, in the United States, Europe, Canada, Australia, South Africa has extensive research. Long-life pavement design concept represents the current high-grade highway pavement structure design and selection of a trend. Compared with semi-rigid base pavement commonly used in our country, long-lived asphalt pavement has obvious advantages. Beginning with the basic concepts and characteristics of long-life asphalt pavement, the methods and issues that should be paid attention to in long-life asphalt pavement design methods, pavement structure construction, regular monitoring of pavement performance, maintenance and replacement of wear layer, etc. are described.
