| 摘 要： | 通过SHRP计划中的弯曲蠕变试验(BBR)研究纤维沥青的低温性能,选择纤维掺量为0%、1%、4%、8%,在-18℃和-12℃两种温度下进行BBR试验,分析了纤维掺量对于试验参数(劲度模量和m值)的影响。另外,在4%纤维掺量下选择3 mm、6 mm、10 mm三种不同长度的纤维进行试验,分析了纤维长度对于沥青低温性能的影响。

| Abstract: | Through the bending creep test in SHRP plan, this paper studied the low temperature performance of fiber asphalt. Choosing the different fiber content and temperature, it carried out the BBR test and analyzed the influence of fiber content on the test parameters （stiffness modulus and m value）. Using three different lengths of fiber, it also had the test under 4 percent of fiber content and analyzed the influence of fiber length on the low temperature performance of asphalt. |
