| 摘 要： | 随着交通渠化和轴载加重,车辙成为沥青路面的主要高温变形形式,它是多因素共同作用的结果。通过车辙试验,分析了掺入德兰尼特纤维的AC-13I及AK-13I沥青混合料高温抗车辙性能的影响因素,并运用灰关联熵分析法对纤维掺量、沥青针入度、沥青用量、4.75 mm筛孔通过率、沥青混合料空隙率、沥青饱和度等影响因素进行分析。研究表明,纤维掺量、空隙率对德兰尼特纤维沥青混合料高温稳定性有重要影响。

| Abstract: | With traffic channelizing and axle-load's increasing,the rut becomes the main form of high temperature deformation.It is the result of interaction of many factors.Based on the wheel rutting test,the influencing factors on high temperature stability of both AC-13I and AK-13I asphalt mixtures are discussed,which different percent of Dolanit AS fibers is added into.Moreover,the grey correlation entropy method is utilized to analyze different factors such as fiber content,asphalt penetration,asphalt content,the percentage of 4.75 mm sized aggregate passing through the mesh,volume of air voids in asphalt mixtures and voids filled with asphalt.The results indicate that fiber content and volume of air voids have a great effect on Dolanit AS fibers-reinforced asphalt mixtures. |
