Abstract: The continuous expansion of highway construction has greatly facilitated people's production and life, and promoted economic development between regions. At present, the country pays more attention to the pace of highway construction, especially the construction of asphalt highways. As a part of highway maintenance system,asphalt mixing plant is an indispensable material output area of highway construction projects in highway construction.It directly affects the development of highway construction and the entire highway industry, and strictly manages its production to ensure the quality of asphalt concrete. Satisfying the production needs will help improve the quality and maintenance efficiency of highway engineering. If the asphalt produced by the mixing plant does not meet the standard, it will directly affect the safety and life of the entire highway and affect the difficulty and efficiency of highway maintenance. In this regard, strengthening the production management of the asphalt mixing plant and improving product quality are of great significance to the entire highway maintenance system.
