Four New Powers! Shiyan Highway Opens New Maintenance Mode of Asphalt Pavement

Zhuxi County Highway Maintenance Center, based on the development orientation of "Two Mountains" practice innovation base, seized the opportunity of building a powerful transportation country, actively introduced small mobile asphalt concrete recycling mixer, took the application of "four new technologies" as a breakthrough point, opened a new asphalt pavement maintenance mode, and injected new kinetic energy into promoting the sustainable development of highways. One is to empower science and technology and turn waste into treasure. Through the dual-mode technology of "hot regeneration + warm mixing", the recycling mixer can efficiently treat waste asphalt mixture and realize resource recycling utilization rate of 90%. Second, innovation-driven, quality maintenance and upgrading.

The main person in charge of Zhuxi County Highway Maintenance Center said,"The new equipment directly completes the whole process of crushing, screening and regeneration on the operation site, which can save 30% cost per ton of mixture and reduce carbon emission by 45%." This technology can not only produce ordinary asphalt mixture, but also customize color environmental protection pavement, providing innovative solutions for beautiful demonstration highway construction. Third, people's livelihood comes first, and service efficiency is improved. In response to the strong public response to the problem of road potholes, the center set up a special attack team to use recycling technology to achieve "repair when it is bad". This innovative technology practice marks that road maintenance in Zhuxi County has officially entered the normal development stage of "four new" technology application. In the future, more intelligent maintenance scenarios will continue to land, making people travel safer, smoother and more comfortable.
