Abstract
In order to prolong the service life of the ultra-thin wear layer maintenance section of asphalt pavement,this paper relies on a municipal road reconstruction project to optimize the mix ratio of asphalt pavement ultra-thin wear layer,and tests the technical indexes of the pavement after construction. According to the test results,the average data of the construction depth of the ultra-thin wear layer asphalt pavement ranges from 0.93 to 1.09 mm,the average data of the swing value ranges from 60 to 68.3 mm,and the average detection value of the water permeability coefficient ranges from 17.4 to 21.6 mL•min-1,and the coefficient of variation is less than 0.5. All of them meet the engineering requirements and the variability of the test data is low,which confirms that the construction effect of the ultra-thin wear layer asphalt pavement in this case is good,and provides a reference for similar maintenance projects.关键词
