en.Wedoany.com Report, On March 25, the pavement engineering AC-13 asphalt concrete surface layer test section for the Eshi-Hong Expressway (Yuxi Section) project was successfully paved. This test section covers the right lane from K13+540 to K13+840, utilizing AC-13 asphalt concrete. The total paving length is 300 meters, with a paving width of 11.35 meters and a thickness of 4 centimeters. The successful paving of this expressway project's test section signifies a critical stage in the project's pavement construction, providing technical parameters and process validation for subsequent large-scale asphalt surface layer construction.

Prior to paving, the project department meticulously planned, conducted detailed safety and technical briefings for the operating personnel, and rigorously inspected and calibrated various mechanical equipment such as pavers and rollers to ensure stable performance and reliable operation. Simultaneously, strict quality control was enforced on raw materials, laying a solid foundation for the smooth paving of the test section. During the paving process, all personnel collaborated efficiently and were deployed in an orderly manner. On one hand, they coordinated the passage of transport vehicles to ensure construction continuity; on the other hand, they continuously optimized construction parameters, strictly adhered to construction specifications and process standards, and implemented full-process monitoring of the entire workflow including asphalt mixture mixing, transportation, paving, and compaction. They precisely controlled core technical indicators such as paving temperature, compaction degree, and smoothness to ensure construction quality met requirements.

The successful paving of this expressway project's test section verified the feasibility of the construction plan and the rationality of the process parameters, accumulating valuable experience for subsequent large-scale asphalt surface layer construction. Upon completion, the Eshi-Hong Expressway (Yuxi Section) will further improve the regional expressway network and enhance the traffic connection efficiency of the central Yunnan urban agglomeration. The project department stated that it will continue to strengthen quality control, organize construction scientifically, and fully advance the expressway project construction.
