Abstract
In this paper,taking a highway asphalt pavement maintenance project as an example,the fiber asphalt gravel sealing technology in asphalt pavement maintenance is deeply analyzed,and the implementation effect is evaluated from three aspects,such as water seepage coefficient,structural depth and appearance.The results show that the appearance of the asphalt pavement after preventive maintenance is smooth,uniform and continuous,and the structural depth of the road surface and the coefficient of water seepage of the pavement meet the requirements of the engineering code.关键词
