This paper analyzes in detail the main influencing factors of pavement smoothness. The smoothness of the underlying layer

the quality of asphalt mixture

construction machinery and construction technology are all the main factors affecting the pavement smoothness in municipal road and bridge construction. Meanwhile

from the three stages of construction preparation

construction and post-construction inspection

the specific application measures of pavement smoothness control technology are systematically expounded

and the pavement smoothness control effects under four different working conditions are compared. The results show that when both the compactness of the paving material and the flatness of the paving layer are at a relatively high level

the flatness of the pavement is optimal.
