近年来我国高速公路的建设突飞猛进,通车里程已超过10万多公里,绝大多数的质量是好的,但也有一些高速公路建成通车后不久,路面就出现早期水损坏现象。沥青路面的早期损坏基本上都与水有关,水的损害严重危害路面的使用寿命和质量。造成这种水损坏,在很大程度上与施工管理混乱,不严格执行规范的施工工艺有关。同时与沥青混合料的级配有着极大的关系;因而,研究沥青路面的渗水与各影响因素的关系,具有重要的意义。
In recent years, the construction of expressways in our country has progressed by leaps and bounds. The traffic mileage has exceeded over 100,000 kilometers. The vast majority of the quality is good, but some expressways have been damaged by water shortly after they were opened to traffic. The early damage of asphalt pavement is basically related to water, and the damage of water seriously jeopardizes the service life and quality of pavement. Caused by this water damage, to a large extent, confusion with the construction management, not strictly enforce the norms of construction technology. At the same time, it has a great relationship with gradation of asphalt mixture. Therefore, it is of great significance to study the relationship between seepage of asphalt pavement and various influencing factors.
