As the third party testing unit of S340 Laolong line surface repair maintenance project, Huaxin Company went to the project construction site on the morning of September 14 to learn the local cold regeneration construction technology of high-performance foam asphalt。
Due to the large amount of waste materials produced in the maintenance and expansion of asphalt pavement, recycling these old materials not only reduces environmental pollution, but also reduces material consumption, which is an important means to realize the sustainable development of highway transportation。
This project is the first time to introduce a new technology - foam asphalt in situ cold regeneration technology in Tongling highway system。Through on-site communication and consultation, the inspection personnel of Huaxin Company have basically mastered the quality control elements of construction, and also laid a solid foundation for the inspection work in the later construction of the project。
