Abstract:Due to the long route coverage and large radiation area of expressway projects, the pavement engineering is a major construction segment within highway engineering, and the material transportation is a key aspect of control. Currently, the traffic safety issues are increasingly prominent, and requirements for traffic safety are constantly being raised. Therefore, it is necessary to formulate the scientific and reasonable traffic safeguard measures. The traffic diversion and safety guarantee measures implemented during the construction of the pavement engineering for the section of Xuwei - Guanyun in Lianyungang - Suqian Expressway are analyzed and summarized. The solutions are proposed for the traffic safety challenges encountered during the highway pavement construction in order to ensure the traffic safety during the construction period, which hopes to provide some reference and assistance to the expressway pavement engineering constructors.
