Loading rate effect, creep and stress relaxation should be attributed to the viscous properties of the sand specimens, but not to the delayed dissipation of excess pore water pressure.
加载速率效应、蠕变以及应力松弛都是砂土材料本身黏性的反映，而与超孔隙水压力的消散无关。

Secondly, bending creep test was practiced to study viscous-elastic characters of asphalt mixtures modified by epoxy resin.
