为了提高开级配排水式磨耗层OGFC沥青混合料的稳定性和抗变形能力，采用一种絮状且性能优良的特种玄武岩纤维作为增强稳定剂。通过选取不同岩纤维掺量，分别进行了0GFC-13混合料的配合比设计及最佳油石比下的各项路用性能检验。研究结果表明，特种玄武岩纤维能很好地吸附沥青并将粗集料骨架粘结成牢固的整体，使得岩纤维增强OGFC--13的高温、低温和水稳等路用性能均得到明显的提高。然而，当岩纤维掺量过高时，部分岩纤维增强沥青胶浆因分散于OGFC-13的连通空隙中而造成空隙率降低，且少量分散不均的岩纤维易形成混合料结构中的薄弱点，从而影响混合料的路用性能。由此确定特种玄武岩纤维的适宜...

In order to improve the stability and deformation resistance capacity of permeable open-graded friction course（OGFC） asphalt mixture, a kind of flocculent special basalt fiber with good performance is used as a reinforced stabilizer. By selecting different mixing a- mounts of the basalt fiber, the mixture ratios of OGFC--13 were designed, then various pavement performances of the OGFC--13 mixtures under the optimum asphalt aggregate ratios were tested. The results show that the special basalt fiber can adsorb asphalt very well to bond the coa...
