摘要
通过分析大量的三轴实验结果，考虑了沥青混合料的流变特性，明确了沥青混合料的流变模型；并利用Ｈｏｏｋｅ－Ｊｅｅｖｅｓ模式搜索法，在ＨＰ微机上进行了数值模拟，给出了沥青混合料相应的流变参数值。结果表明。
By analysing a large number of experimental results obtained from triaxial tests, some rheological characteristics of bituminous mixtures are studied in this paper, and a rheological model for this material is proposed. Moreover a numerical simulation work is carried out by setting up a HP Basic program and applying the Hooke Jeeves' Pattern Search Method, to determine thses rheological parameters. This study shows that the Burgers' model may generally characterize the rheological behaviour of bituminous mix.
