基层级配对基面层间粘结性能的影响

Effect of base course gradation on the interlayer bonding performance between the surface and the base

山区公路由于小半径和长大纵坡路段多,路面推移现象比较多见。文章分析了基层级配类型对基面层间粘结性能的影响,认为骨架-密实结构类型基层对提高基面层间粘结性能具有明显提高作用。除了满足现行规范有关指标要求外,基层施工应尽量使用骨架-密实结构类型。

The shoving of asphalt pavement is often found in a mountain highway due to the minor radius and the long - steep slope section. This article analyzes the effect of gradation type of the base course on the interlayer bonding performanee, and then it is considered that the base with framed dense structure has an obvious promotion to improve the interlayer bonding. In addition to meeting the requirements for the relative indicators in current specifieation, the framed dense structure should be used as far as possible in the construction of base course.
