| 摘 要： | 半刚性基层沥青路面已经成为了我国高速公路路面结构的主流模式,但是半刚性基层容易产生开裂,并逐步向面层扩展,形成反射裂缝。设置应力吸收层可以有效地减缓半刚性基层的反射裂缝。根据应力吸收层的功能特性,同时引入美国Superpave配合比设计思想,对应力吸收层混合料进行了配合比设计。

Composition Design of Asphalt Sand Stress Absorbing Layer Material of Semi- rigid Base Course Pavement |
| |
| Abstract: | Semi-rigid base course asphalt pavement has become the main stream model of expressway pavement structure of our country,but crack is easily caused and expands gradually to the surface course to form reflection crack.Stress absorbing layer could effectively reduce the reflection crack of semi-rigid base course.According to the functional characteristics of stress absorbing layer,American Superpave mix ratio design concept is introduced at the same time,and mix design is made for mixture of stress absorbing layer. |
