| 摘 要： | 根据目前国内高速公路水泥稳定碎石基层的使用情况，针对苏南地区高温多雨，水泥稳定碎石基层在湿度变化时易产生干缩裂缝这一缺陷，提出了改善收缩性能、减少干缩量的水泥稳定碎石混合料的级配组成范围及级配组成设计方案，分析了不同级配组成对干缩变形特性的影响． |
| 关 键 词： | 水泥稳定碎石 级配组成 干燥收缩 干缩应变 平均干缩系数 |

| Abstract: | Based on a study of the current conditions of China's cement-stabilized macadem base of speedway,the gradation composition scopes and aggregate gradation composition design scheme of (cement)-stabilized macadam with good crack resistance are proposed,and the effects of different gradation composition on dry shrinkage deformation properties are analyzed to deal with the default of cracking of cement-stabilized macadam base course that tends to come forth under the condition of moisture(changing) in the south area of Suzhou. |
| Keywords: | cement-stabilized macadam gradation composition dry shrinkage dry shrinkage strain average dry shrinkage coefficient |
