中文摘要：

通过对环氧沥青进行频率扫描、蠕变试验等动态剪切流变试验，分析了环氧沥青的粘弹性能．与普通改性沥青相比，环氧沥青表现出完全不同的粘弹特征：其在较大的温度和频率范围内均表现出较好的弹性性能，粘性所占成分很少；其蠕变柔量小约4个数量级，有着更好的高温稳定性能；其复数模量随频率降低（温度升高）而降低，并与贮存模量共同趋于稳定值，表现出明显的弹性特征，而在高频（低温）条件下则显示出一定的粘性特征．结果表明，环氧沥青具有很好的高温抗变形和低温抗裂性能，是一种理想的路面建筑材料．

英文摘要：

Dynamic shear rheological tests including the frequency sweep and the creep test were performed to study the viscoelastic characteristics of epoxy asphalt. The results show that epoxy asphalt possesses the viscoelastic characteristics significantly different from those of the common modified asphalt. Epoxy asphalt behaves good elastic properties in a lager scope of temperature and frequency, with a very low viscous composition. It is of better high- temperature stability because its creep compliance is about 4 orders of magnitude lower than that of the common asphalt. It possesses obvious elastic characteristics because its complex modulus decreases with the frequency （or with the increase of the temperature） to a constant value together with the stock modulus. Moreover, it shows viscous property to a certain degree in high-frequency condition （or at high temperature）. All these findings indicate that epoxy asphalt is a kind of perfect construction material for pavement due to its good high-temperature distortion resistance and low-temperature crack resistance.
