| 摘 要： | ;半刚性基层的温缩裂缝会导致路面产生反射裂缝,严重影响路面结构的性能。不同类型的半刚性基层,若组成材料不同,则温缩性能也存在差异。通过对四种不同的半刚性基层材料90d的温缩系数进行量测和分析,结果表明：水泥用量是影响半刚性基层温缩性能的主要因素,四种材料抗温缩性能优劣排序为：二灰碎石〉三灰碎石〉水泥粉煤灰稳定碎石〉水泥稳定碎石。

| Abstract: | The temperature shrinkage crack of semi-rigid base will cause reflection crack in pavement and affect the performance of pavement structure seriously.The temperature shrinkage properties of different semi-rigid bases differ from each other because of material composition.By measuring and analyzing the 90 day temperature shrinkage coefficient of four semi-rigid base materials,the result shows that the content of cement is the main influencing factor of temperature shrinkage property of semi-rigid base,and th... |
