本文进行了不同种类的沥青下封层室内试验,结果表明在同样的试验条件下,稀释沥青6#对基层材料具有较好的渗透能力,1#对水泥稳定碎石基层具有较好的渗透能力。其他乳化沥青材料对基层基本无渗透能力。在同样的试验条件下,同种乳化沥青材料的渗透性能与基层材料的性质有关。同种乳化沥青对水泥稳定碎石基层的渗透能力最好,其次为二灰稳定碎石,再次为水泥混凝土。
In this paper, different types of bitumen under the seafloor were tested in laboratory. The results show that under the same test conditions, the diluted bitumen 6 # has better penetration ability to the base material, and 1 # has good penetration ability to the cement stabilized macadam base . Other emulsified asphalt material basically impermeable to the grassroots. Under the same experimental conditions, the permeability of the same emulsified asphalt material is related to the properties of the primary material. The same kind of emulsified asphalt has the best permeability to the cement stabilized macadam base, followed by lime-flyash stabilized macadam and cement concrete again.
