SMA路面的油斑病害初探及预防措施

Preliminary Probing into and Prevention Measure of Oil Spot Disease on SMA Pavement

该文从SMA沥青混合料的拌和、施工等环节,提出了SMA路面的离析性油斑和迁移性油斑概念。结合深圳深南路路面修缮及交通改造等工程,运用Weissenberg效应理论和粘弹性力学及材料学原理,对SMA沥青路面的油斑病害做了初步分析,并提出了相应的预防措施。

The article puts forward the conceptions of isolating oil spot and transferring oil spot from the links of the mixing and construction of SMA asphalt mixture.Combined with the works of the pavement renovation and traffic rebuilding of Shennan Road in Shenzhen and applying the Weissenberg effect theory,the viscoelastic mechanics and the material mechanics principle,the article carries out the preliminary analysis of the oil spot disease on SMA asphalt pavement and puts forward the relative prevention measures.
