摘　　要：对比试验了现有的沥青-集料粘附性,提出了运用超声波模拟动水压力作用下沥青从集料表面剥落的粘附性测试方法。从试验结果可以看出,这一试验方法可以较好地区分不同集料的粘附性能。集料的粘附性不仅与其岩性有关,还受到表面形态的影响。In this study, several available asphalt-aggregate adhesion test methods were compared and analyzed. A kind of adhesion test method using ultrasonic is recommended to simulate asphalt stripping from aggregate surface under dynamic hydrodynamic pressure. The test results show this test method can distinguish adhesion performance of different aggregate. The adhesion of aggregate is affected by not only its lithology, but also the surface morphology.
