本文主要简述了乳化沥青路面在使用过程中所遇到的主要水损害类型,并提出将乳化沥青路面水损害按机理分为浸入型水损害、浸出型水损害2大类型;其中:(1)乳化沥青路面浸入型水损害与热拌沥青路面类似,其损害机理基本一致;(2)乳化沥青浸出型水损害为其特有损害类型,该类型的损害机理为沥青部分组分被溶有乳化剂的水浸出,而造成沥青组分比例改变,粘附性降低,从而形成路面病害。
In this paper, the main types of water damage encountered in the emulsified asphalt pavement are briefly described. It is proposed that the water damage of the emulsified asphalt pavement is divided into two types according to the mechanism: immersion water damage and leaching water damage. Among them, ) The damage of emulsified asphalt pavement immersion water is similar to that of hot asphalt mixture, and its damage mechanism is basically the same. (2) The damage of emulsified asphalt leaching type water is its peculiar damage type. The damage mechanism of this type of asphalt is that part of asphalt is dissolved and emulsified Water leaching agents, resulting in a change in the proportion of asphalt components, reducing adhesion, resulting in road disease.
