摘要
为了控制反射裂缝,基层材料的性能优化是简单有效的技术途径,采用减少基层材料用水量、降低水泥用量以及降低水的表面张力等方法均有助于减少收缩裂缝的产生.试验结果表明,水泥稳定碎石基层中掺加粉煤灰、减水剂、减缩剂能明显改善基层抗收缩性能,通过采用复合掺加的方法效果更佳.
To optimize properties of the crushed rock is a simple and effective method to control the reflective cracking. There are some measures to reduce the shrinkage of the crushed rock, such as： decreasing water content and cement percentage, reducing surface tension of water. The test study shows that shrinkage resistance of the crushed rock base can be improved by mixing with fly ash, water reducing agent and shrinkage reducing agent each other, it will be better for the crushed rock to mix with fly ash, water reducing agent and shrinkage reducing agent proportionally.
