| 摘 要： | 对大纵坡路段路面破损的主要原因进行了分析,提出了路面破损的解决措施。通过对试验路路面结构方案技术指标、施工难度、路面耐久性及经济性的对比,推荐了两种路面结构组合形式,能够较好地解决山区公路在纵坡坡度及长度较大(简称"大纵坡")路段的路面损害问题。

| Abstract: | The major reason for pavement damage at the section with large longitudinal slope is analyzed,and measures for solving pavement damage are proposed.Through the comparison of technique data,construction difficulty,pavement durability and economical efficiency of pavement structure scheme of test road,two kinds of combination layouts of pavement structure are recommended,thus solving pavement damage problems at the section with larger longitudinal slope and length(for short "large longitudinal slope") well. |
