均匀设计在SMA骨料级配设计中的应用

Uniform design for aggregate gradation of SMA

采用均匀设计方法 ,对 SMA混合料骨料级配进行了优化设计。进行了高温车辙试验和低温弯曲试验 ,通过对试验结果回归分析处理 ,得到了关于 SMA最佳骨料级配。

Based on the method of uniform design,the optimum grading designs for different level aggregate contents were present. The rutting resistance test and low temperature tensile test were carried out. An optimum aggregatc gradation of SMA was obtained from the test results.
