| 摘 要： | 在高性能等级（PG）温度、多应力水平和多个周期下，用重复蠕变与恢复试验（RCRT）测试聚合物改性沥青的恢复反应，依此鉴别改性沥青中是否存在弹性聚合物并确定其含量。为沥青材料的性能试验提供一个标准的试验方案。将RCRT法与传统的弹性恢复试验作比较，突出RCRT的优点及其应用前景。

| Abstract: | The method of repeated creep and recovery test (RCRT) is conducted for testing the recovery reflection of polymer-modified asphalt binders at high Performance Grade(PG)temperature,multiple stress levels and many creep and recovery cycles. According to the recovery reflection, the presence of elastic polymer in a polymer-modified binder can be identified and its content can be determined. The RCRT standard method of property test of asphalt material can be provide by the RCRT. RCRT has many advantages and gr... |
