木质纤维沥青混合料性能研究

RESEARCH ON PERFORMANCE OF ASPHALT MIXTURES WITH CELLULOSE FIBER

近年来,从总体性能评价和工程上应用的经济性来考虑,路用木质纤维稳定剂成为了建设SMA沥青路面首选的一种添加材料。但究竟是使用颗粒状路用木质纤维的好,还是使用松散状路用木质纤维的好,目前还没有一个明确的说法。本研究选用颗粒状路用木质纤维和松散状路用木质纤维进行路用性能试验,试验结果表明,颗粒状路用木质纤维较松散状路用木质纤维在路用性能上有明显优势。

In order to consider the economy of overall performance evaluation and engineering applications of fiber stabilizer, in recent years, the cellulose fiber stabilizer has become preferred material in SMA building. However, there are different formulations about which is better of using granular cellulose fiber for road construction or loose cellulose fiber for road construction. In this paper, the way with performance test of granular cellulose fiber was compared with cellulose fiber for road construction by experiment. The results show that the way with performance of granular cellulose fiber for road construction is obviously superiority than loose cellulose fiber for road construction.
