摘要
通过弯曲试验和劈裂试验,分析了水泥替代部分或全部矿粉对沥青混合料抗裂性能的影响。试验结果表明;使用应变能密度理论能够比较准确的评价沥青混合料抗裂性能;使用水泥替代部分或全部矿粉和对沥青混合料的抗裂性能并无明显影响。
By flexural test and split test , the effect of part or total replacement of mineral powder with cement on and-cracking performance of asphalt mixture is researched. The test results indicate the strain energy method is more effective .It reflects asphalt mixture anti-cracking performance accurately. When the cement is used instead of mineral powder, the influence on the anti-cracking performance of asphalt mixture especially the low-temperature performance is little.
