摘　　要：动水压力是导致沥青路面病害频发的诱因之一。文中综述了国内外沥青路面动水压力的研究现状,分析了沥青路面动水压力产生原因及影响因素,其中车辆行驶速度、行车荷载以及沥青路面空隙率等对沥青路面动水压力影响较大。针对该研究领域现存问题,提出应建立统一的测试标准及方法、研制更加科学合理的室内模拟试验装置等措施。Hydrodynamic pressure is one of the important causes of frequent occurrence of asphalt pavement defects.In this paper,domestic and foreign research status of hydrodynamic pressure are reviewed,the production of hydrodynamic pressure imposed on asphalt pavement and its influencing factors are analyzed.The vehicle speed,vehicle load and air voids of asphalt pavement have great influence on hydrodynamic pressure.In view of the existing problems in this field,it is suggested that unified test standard and method should be established,and more scientific and reasonable indoor simulation devices should be developed.
