摘要
分析了沥青路面的层间黏结性能产生机理,以及这种层间黏结对路面剪切和弯沉的抵抗效应。从黏层性能和上下沥青面层差异性两个方面深入分析了影响沥青面层层间黏结性能的主要因素,主要包含黏结材料、黏层污染程度、施工温度、层间级配差异、层间结构组成五个因素,最后提出了设计施工措施,使得沥青面层黏结良好形成整体受力和变形。
The interlayer bonding performance of asphalt pavement and its mechanical mechanism are analyzed,and the impact of this interlayer bonding on the pavement bending and shearing effects is also studied.The main influence factors on the interlayer bonding performance of asphalt pavement are further analyzed from two aspects of the bonding layer performance and the upper-lower asphalt layer difference mainly including five factors of bonding material,bonding layer contamination,construction temperature,interlayer gradation difference,and interlayer structural composition.Finally,the design and construction measures are proposed to make the bonding of asphalt pavement good to form the overall stress and deformation.
