The linear viscoelastic (LVE) characterisation of asphalt mixtures in time domain is generally performed at temperature lower than 30°C to prevent the effect of permanent deformation. Although LVE properties in frequency and time domain can be mathematically interconverted, the determination of relaxation modulus and creep compliance through experiment is also necessary. This paper presents a method for determining the creep compliance of asphalt mixtures at intermediate and high temperature, at which permanent deformation takes place. Since the recovery of creep-recovery test is a pure LVE process, it was used to back-calculate the creep compliances (CCs) at various investigating temperatures. The results show that the CCs back-calculated from creep-recovery data achieve a good level of accuracy and repeatability. In addition, the obtained master curves of CCs agree well with those interconverted from dynamic modulus test data and the same shift factors are applicable for both creep compliance and dynamic modulus, phase angle.

沥青混合料在时域中的线性粘弹性（LVE）表征通常在低于30°C的温度下进行，以防止永久变形的影响。尽管可以在频率和时域上对LVE属性进行数学转换，但是通过实验确定松弛模量和蠕变柔度也是必要的。本文提出了一种确定沥青混合料在中，高温下会发生永久变形的蠕变柔度的方法。由于蠕变恢复测试的恢复是一个纯LVE过程，因此可用于在各种研究温度下反计算蠕变柔量（CC）。结果表明，根据蠕变恢复数据反算的CC达到了较高的准确性和可重复性。此外，
