| 中文摘要: |
| 根据沥青混合料的结构特性和强度构成机理,借鉴逐级填充理论的多级嵌挤级配设计思想和旋转压实试验方法,对沥青拌合楼热料仓所取集料试样进行合成级配设计,以贝雷法验证其级配的合理性,得出具有嵌挤骨架密实结构的沥青混合料级配,工程应用效果良好。 |
| 英文摘要: |
| Based on the structure characteristic and the strength constituted mechanism of asphalt mixture,multilevel dense built-in grading design idea of the gradually filling theory and the gyratory compaction experimentation method are referenced,the synthesis gradation of the aggregate sample taken from the hot material storehouse of asphalt mixing building are designed.The rationality of the gradation is validated by the Bailey method,and the asphalt mixture grading that have built-in skeleton densified structure is taken out,and is applied well in the engineering. |
