摘要
介绍水泥混凝土路面隔离层常用材料,采用自行研制的冲刷试验设备,对沥青碎石、微表处、沥青混凝土隔离层的冲刷性能进行对比分析和研究。研究结果表明:沥青混凝土隔离层的抗冲刷性能要优于其他抗冲刷材料,其随隔离层厚度增长而增强,随油石比增大而增强;微表处隔离层具有较好的抗冲刷性能,其随厚度增长而增强。
This paper introduces common materials for separating layer on cement concrete pavement, and performs comparative analysis and study of the anti - erosion property of asphalt macadam, micro - surfacing and asphalt concrete separating layer by means of self - developed washout test equipment. The results of research show that the anti - erosion property of asphalt concrete separating layer are superior to other anti - erosion materials, it enhances with increase of the thickness of separating layer and increase of the asphalt - aggregate ratio ; the separating layer at micro - surfacing exhibits good anti - erosion property and enhances with increases of the thickness.
