长期以来,我国对高速公路路面的预防性养护一直不甚重视,养护技术、理论研究也相对滞后,加上超载现象的严重,其造成的主要后果是我国92%的高速公路路面寿命是5～7年,不及美国、加拿大沥青路面寿命的一半。微表处技术作为对高速公路进行预防性养护最经济有效的方法,近年已受到越来越多的重视。众所周知,水损害是造成路
For a long time, the preventive maintenance of freeway pavement in our country has been paid little attention. The maintenance technology and theoretical research are relatively lagging behind. With the serious overloading phenomenon, the main consequence is that 92% of the expressway pavement life in our country is 5 ~ 7 years, less than the United States, Canada half the life expectancy of asphalt pavement. Micro-surfacing technology, as the most cost-effective method for preventive maintenance of expressways, has received more and more attention in recent years. It is well-known that water damage is the cause of the road
