沥青路面结构内部的孔隙水在高速行车荷载的作用下造成的瞬时超孔隙水压力，是造成路面水损害的重要原因。由孔隙水压产生的附加应力，使孔隙加大，贯通形成宏观裂纹并逐渐扩展，加速了沥青路面的破坏。针对沥青路面水损害问题，本文系统地介绍了国内外研究者在这方面所做的研究工作，同时对沥青路面水损害产生的原因及过程进行了详细分析，并在此基础上提出了一系列沥青路面的水损害防治措施。“,”The instantaneous super pore water pressure produced by the pore water of the inner structure of asphalt pavement, under the action of the high speed wheel load, is an important reason that results in water damage of the pavement. Additional stess produced by pore water pressure, make the pore enlargement, make pore become large and form the macroscopic crack which expands gradually, accelerating the breakage of the asphalt pavment.Aiming at the problem of water breakage of the asphalt pavement, this paper systematically introduces the domestic and international research for doing this works, simultaneity analyses the reason and processes of water damage of the road surface in detail, and puts forward a series of measures to prevent it.
