| 摘 要： | 通过室内试验研究了水泥稳定碎石基层混合料的强度和收缩性能，对其性能的影响因素和影响规律进行了分析，并根据工地现场试验室的试验结果，确定了满足强度要求兼具较好抗裂性能的水泥稳定碎石基层混合料配合比方案。室内试验研究表明随着水泥用量的增大．混合料的强度和收缩均会增大，因此建议在满足强度要求的基础上，尽量减小水泥用量以同时获得良好的收缩性能。 |
| 关 键 词： | 水泥稳定碎石 强度性能 干缩 温缩 |

| Abstract: | The performance of the strength and shrinking rules of base mixtures of cement stabilized crushed stone is studied in this paper by laboratory tests cement content and the aggregate gradation for both high . On the basis of the field test results, the best strength and better crack resistance are chosen. The laboratory test results indicate that the strength and the shrinkage of the semi-rigid material as the cement content increases. Therefore, the cement content should not be too much in order low-shrinkage. incr ease to get a low-shrinkage. |
| Keywords: | cement stabilized crushed stone strength performance dry shrinkage temperature shrinkage |
