摘要
采用细观力学理论和粘弹对应原理对环氧沥青玛蹄脂的粘弹性能进行预测。对4种不同体分比的固化后环氧沥青玛蹄脂试件,在20℃下进行单轴压缩蠕变试验。试验表明,理论预测的粘弹性能与试验值相差随着体分比增大而增大。采用愈渗理论对预测值进行校正,校正后的结果和试验值吻合较好。
The aim of this paper was to predict the viscouselastic property of epoxy asphalt concrete using micromechanism and viscoelasticity theory.Four cured epoxy asphalt mastic specimens with different volume distribution ratio were tested by the unilateral axial compressing creep test under 20℃.The tests results showed that the difference from the predicted tends would be greater with greater volume distribution ratio.After revised by methods of percolation theory,the predicted became consistent with results of experiments.
