| 摘 要： | 半刚性基层材料目前已广泛应用于我国高等级公路路面结构中,但是随着温度和湿度的变化,这种材料容易产生开裂,影响路面使用性能。本文通过对几种半刚性基层材料进行室内干缩和温缩试验研究,分析其干缩应变、干缩系数、温缩应变、温缩系数等参数的变化规律,为科学地进行半刚性基层材料配合比设计和改善其抗裂性能提供一些基础资料。 |
| 关 键 词： | 半刚性基层 干缩 温缩 裂缝 |

| Abstract: | Semi-rigid base course materials are widely used in the pavement structure in China,but with variations in temperature and humidity,this kind of materials easily cracks and influences the working performances of pavements.Through the lab experiments of dry shrinkage and temperature shrinkage of some semi-rigid base course materials,some parameters such as the strain,coefficient of dry shrinkage and temperature shrinkage are obtained,that provides some fundamental information for the mixture ratio design of semi-rigid course and improving its crack-resistance performance. |
| Keywords: | semi-rigid base course dry shrinkage temperature shrinkage crack |
