在我国已建成的高等级公路中,水损害成为一个无法回避的问题。就我国高等级公路沥青路面来说,不管是采用哪种级配的表面层,在建成通车之后不长时间,由于水进入沥青面层之后,加上大量高速行驶车辆尤其是那些重型载重车的作用下,各种水破坏现象就会频繁产生,具有破坏速度快且危害大的特点,已经成为目前造成高等级公路路基、路面破坏的主要因素。文章分析了高等级公路水损害现象及其产生的原因,提出了有效处治的建议。
Water damage has become an unavoidable problem in our country’s completed high-grade highways. As for our country’s high-grade highway asphalt pavement, no matter what kind of graded surface layer, not long after the completion of the traffic, as the water into the asphalt surface, coupled with a large number of high-speed vehicles, especially those heavy truck Under the action of all kinds of water damage will occur frequently, with the destruction of fast and harmful to the characteristics of large, has become a high-grade highway subgrade and pavement damage the main factors. The paper analyzes the phenomenon of water damage on high-grade highway and its causes, and puts forward suggestions for effective treatment.
