对添加纤维后沥青胶浆性能改善的研究和分析

Study and Analysis on the Modification and Improvement of Asphalt Mixture Performance after Appending Polymer fibers

介绍了利用动态剪切流变仪(DSR)对添加聚合物纤维后的沥青胶浆进行试验分析的过程和成果,这些成果证实了聚合物纤维对沥青胶浆的影响作用.在实验室获得不同的纤维用量对沥青胶浆软化点影响结果的基础上,应用传统经验公式法对添加纤维后的沥青的其他几大指标进行了综合分析,最后定量地分析了添加聚合物纤维对沥青胶浆的性能改变.

In this paper, the experimental processes and results of DSR that showed the influence of different polymer fibers on asphalt cement were introduced first, then a comprehensive quantitative analysis for the effect of polymer fibers upon modification and improvement of asphalt mixture performance was carried out by using traditional empirical formula method according to experimental data which was obtained on the basis of the effect on softening point of asphalt cement.
