为了研究阳离子乳化沥青在水中的渗透性能以及其在水中的浸出动力学,本文引用电化学试验方法以及反应动力学试验研究方法和建模方法对阳离子乳化沥青在水中的浸出性能及浸出性能进行试验研究。通过交流阻抗技术分析,可将乳化沥青试件在酸性水体的浸泡过程分为3个阶段,第一阶段为浸泡初期,该阶段时长可作为衡量抗渗性能的主要指标,第二阶段为浸泡中期,此时沥青微孔道逐渐扩大、沥青膜开始起泡肿胀,第三阶段为浸泡后期,此时沥青膜开始大面积起泡、肿胀,并剥离金属电极表面,已基本失去粘附性。
In order to study the permeability of cationic emulsified asphalt in water and its kinetics of leaching in water, the electrochemical test method, reaction kinetic experimental research method and modeling method are used to test the leaching performance and leaching performance of cationic emulsified asphalt in water the study. Through the analysis of AC impedance technology, the emulsified asphalt specimen can be divided into three stages in the immersion process of acidic water. The first stage is the initial stage of immersion. The duration of this stage can be used as the main index to measure the impermeability. The second stage is the mid-stage At this time, the micropore of asphalt is gradually enlarged, and the bitumen membrane begins to swell and swell. The third stage is the later stage of soaking. At this moment, the bitumen membrane begins to blister and swollen in large area, and stripped the surface of the metal electrode.
