Engineering Design and Stability Analysis of Highway Subgrade Slope

In order to improve the construction level of highway pavement engineering, this paper discusses the factors that affect the construction quality of the pavement from the aspects of raw materials, asphalt mixture, personnel, etc., and screens out the dynamic control index of asphalt mixture pavement. Based on the theory of average-standard deviation (extremely poor) control chart, the dynamic control method and key points of asphalt pavement construction quality are analyzed, in order to further improve the dynamic management level of highway pavement.
