Introduction With the improvement of the grade of mountainous highway reconstruction, the requirements on pavement quality, smoothness, durability and driving safety and comfort of highway asphalt pavement are getting higher and higher. However, mountainous roads are affected by different topography, geology , Climate and hydrology and other natural conditions, the route laid more curve, and the radius is smaller, vertical and vertical fluctuations vary widely, the road width is narrow, the pavement asphalt pavement more difficult to pave the way, although the pavement construction of high degree of mechanization , But due to the external objective conditions and construction process defects caused by the quality of asphalt pavement there is still a certain degree of
