高速公路开始修建至今已有将近80年的历史,世界各国的发展水平不一。据不完全统计,至2012年底,中华人民共和国高速公路的通车里程已到96000公里,比2011年新增11000公里,超越了美国的92000公里的洲际公路。在我国高速公路体系中,沥青路面占到总路面里程的90%以上。因为沥青路面的使用性能除了影响行驶舒适性外,还直接影响行车的安全性。但随着交通量的不断增大,长期受到行车荷载和大气破坏、降水破坏等作用,为高速公路带来灾害性损坏,大大缩短了高速公路的使用寿命,使路面的使用性能变差,增加行车难度,降低运输效率等问
The expressway has been under construction for nearly 80 years now, and the development level of various countries in the world is different. According to incomplete statistics, by the end of 2012, the opening of the People’s Republic of China’s expressway has reached 96,000 kilometers, an increase of 11,000 kilometers over 2011, surpassing the 92,000 kilometers of the U.S. intercontinental highway. In our expressway system, asphalt pavement accounts for more than 90% of the total pavement mileage. As the performance of asphalt pavement in addition to affecting the driving comfort, but also a direct impact on traffic safety. However, with the continuous increase of traffic volume, long-term effects of driving load, atmospheric damage and precipitation damage have brought disastrous damage to the expressway, greatly shortening the service life of the expressway, deteriorating the serviceability of the road surface and increasing Driving difficulty, reduce transport efficiency and other questions
