Asphalt-aggregate interface adhesiveness determination method considering dynamic water pressure

The invention provides an asphalt-aggregate interface adhesiveness determination method considering dynamic water pressure, which comprises the following steps: preparing an asphalt film sample by adopting short-term aged asphalt, and pasting a drawing spindle on the asphalt film sample to obtain an experimental sample; placing the experimental sample on a storage rack in an ultrasonic device, adding a water medium into the ultrasonic device, and impacting the experimental sample by adopting ultrasonic waves; and carrying out a drawing test on the experimental sample after ultrasonic impact to obtain the adhesion strength of the asphalt-aggregate interface after ultrasonic impact, and quantitatively evaluating the adhesion performance of the asphalt-aggregate interface after the ultrasonic simulation hydrodynamic pressure test. 本发明提供一种考虑动水压力的沥青-集料界面黏附性确定方法，该方法通过采用短期老化沥青制备沥青膜样品，并在沥青膜样品上粘贴拉拔锭子，得到实验样品；将实验样品放置在超声波装置内的置物架上，并在超声波装置内加入水介质，采用超声波冲击实验样品；对超声波冲击后的实验样品进行拉拔测试，得到沥青-集料界面受超声波冲击后的黏附强度，本发明能够实现量化评价超声波模拟动水压力试验后的沥
