| 摘 要： | 采用均匀设计方法,研究不同状态下不同级配粗集料的密实性和稳定特性,为合理设计粗集料级配奠定基础。研究结果表明,不同粗集料由于表面纹理、颗粒形状和力学性能的不同,其密实性和稳定性不尽相同。粗集料级配优化设计,应对其密实性和稳定性进行综合控制。 |
| 关 键 词： | 密实度 稳定性 级配设计 均匀设计法 |

| Abstract: | Using the uniform design method, the density and stability of different course aggregates were studied in this pa per. The results indicated that different course aggregates had different density and stability for their different surface texture particle shape and mechanical properties. The optimized mix design of course aggregate was based on density and stability. |
| Keywords: | density stability mix design uniform design method |
