Reporters learned from the recent 2021 Hebei Transportation Investment Group work conference that the Jingde Expressway will be completed and open to traffic by the end of May this year.

　　The Jingde Expressway (Phase I Project) starts from the Beijing-Hebei boundary east of Jijiazhuang Village, Gu'an County, Langfang City, Hebei Province, and connects with the Beijing section (the north-south terminal contact line of Daxing International Airport). It passes through Gu'an East, Yongqing West, Bazhou East, and Wen'an West, and ends at the intersection with the Jinshi Expressway in Liangzhao Town, Renqiu City. The project is 87 kilometers long, and a 5.5-kilometer Bazhou East interchange connecting line is built simultaneously.

　　Currently, the project is at a critical stage of construction. Reporters learned from the construction site that during the Spring Festival this year, more than 2,000 construction workers stayed on the Jingde Expressway to achieve the goal of not stopping work during the holiday.

　　As one of the four vertical lines in the “four vertical and three horizontal” regional expressway network of the Xiong'an New Area, the Jingde Expressway has focused on and achieved breakthroughs in three major technological innovations: permanent pavement, intelligent construction, and smart expressway.

　　The person in charge of the temporary preparation office of the Jingde Expressway introduced that in the paving of the “bottom layer” of asphalt pavement, construction workers laid a new material called “permanent pavement” on the entire 87-kilometer road surface of the Jingde Expressway. This material, mainly rubber powder modified asphalt, can achieve “no minor repairs for 15 years and no major repairs for 20 years.”

　　The rubber powder added to the asphalt comes from waste tires. The rubber powder obtained through crushing not only improves the thermal stability of the asphalt and extends the service life of the pavement but also realizes the reuse of waste tires.

　　As it is the first large-scale use of the new “permanent pavement” material in expressway construction, there is a lack of relevant technical standards. The construction unit, through organizing scientific research, gradually explored and initially formed a set of construction standard systems for “permanent pavement.”

　　In terms of intelligent construction and smart expressway construction, the Jingde Expressway has built a full-process safety risk early warning system through top-level design.

　　The person in charge of the temporary preparation office of the Jingde Expressway gave an example: in key parts such as disc-buckle supports, large hanging baskets, swivel construction, and hub interchanges, intelligent monitoring and cloud monitoring systems are adopted, and multi-dimensional information fusion analysis technology is used to achieve online video intelligent monitoring, cloud monitoring of safety risks, and real-time early warning, effectively avoiding construction risks.

　　Implement full-cycle meteorological monitoring and early warning for construction, and deploy construction safety guarantee measures in advance. Pavement construction adopts a “double insurance” of mechanical anti-collision and radar early warning systems, achieving multi-level safety warnings such as 10-meter monitoring, advanced honking, speed reduction and gear shifting, and automatic braking.

　　All participating units actively promoted multiple technological innovations such as drone inspections and safety broadcasts, mobile APP hidden danger investigation and governance, and BIM safety briefings, improving the construction safety level and management efficiency of the Jingde Expressway and realizing smart construction of a smart expressway.

　　After completion and operation, the Jingde Expressway will use a traffic simulation platform to collect real-time traffic volume and environmental status data through five major systems: perception, control, management, coordination, and service. It will analyze and predict collision risks, continuously improve simulation calculation accuracy, achieve real-time collision risk prediction and early warning, significantly reduce accident rates, and build a smart expressway with dynamic control and real-time early warning.

　　After opening to traffic, the Xiong'an New Area will achieve 1-hour access to Beijing and Tianjin, laying the foundation for improving the regional road network of the Xiong'an New Area and realizing rapid collection and distribution between Hebei Province and areas to the south and Beijing Daxing International Airport.
