摘　　要：在我国高速公路路面建设中,大部分采用半刚性材料作为基层.近几年公路专家,为克服半刚性沥青路面的结构缺陷,开始了柔性基层技术的研究,为对比分析柔性基层与普通水泥稳定基层的路用性能,辽开高速公路路面工程在K3 ＋300 ～ K8 ＋000右幅铺筑12cm级配碎石联结层试验段.对该试验段的级配碎石联结层配合比设计进行了介绍,并结合工程实践,对级配碎石施工过程中应该注意的一些问题进行了说明.In the construction of highway pavement, most roadbeds use semi - rigid material. In recent years, in order to overcome the structural defects of semi - rigid asphalt pavement, highway experts began to research flexible base technology. For the comparative analysis of road performance between flexible base and ordinary cement stabilized base, a 12cm link - layer of graded broken stone test section was built in Liaokai highway pavement engineering at right pavement of K3 ＋ 300 - K8 ＋ 000. This paper introduces the mix ratio design of the link - layer of graded broken stone. Combining with engineering practice, this paper illustrates some problems that should be noticed during the construction process of graded broken stones.
