沥青路面水损坏分析及防治措施研究

摘要

沥青路面的水损坏是路面使用过程中的一种常见病害。分析路面结构内部水分来源以及沥青路面水损坏的影响因素，通过测定沥青的三大指标以及沥青混合料的劈裂抗拉强度，证明水分的侵蚀对沥青及其混合料造成的影响，并提出防治路面水损坏的措施以加强沥青路面水损坏预防，对于提高路面使用性能，延长路面使用寿命具有重要的实际意义。%Water damage on asphalt pavement is a common disease during its service. The factors influencing water source inside the pavement structure and water damage that three indices of asphalt and the splitting tensile strength of asphalt pavement are analyzed to the extent of asphalt mixture are measured to prove the influence of water erosion on asphalt and its mixture; and the measures controling water damage are suggested to enhance the prevention thereof. It is very important for improvement of pavement and extension of its service life. on pavement performance
