Abstract

Abstract: In this paper,the author utilizing advanced material test systerm(MTS) makes an uniaxial static creep test on bitumen mixture specimens made by SGC.and obtains creep curves between deformation and time of these specimens. Basing on these curves,the author analyese the effect on creep performance of bitumen mixture exerted by temperature and load level

Key words: bitumen mixture, creep, stiffness, material test systerm (MTS), superpave gyratory compactor(SGC)

摘要： 作者在本文采用先进的材料系统(MTS)，对旋转压实机(SGC)成型的试件了进行单轴静载蠕变试验，得出了沥青混合料在荷载作用下变形随时间的蠕变变形曲线，并根据这些蠕变曲线分析了不同温度和荷载水平对沥青混合料蠕变性能的影响。
