Recently，Guizhou Daily《Ecology》An article was published in a prominent position in the edition.《Let the asphalt road put on the new clothes of environmental protection technology——Visit the first green low-carbon recycling and maintenance base in Guizhou》The news，This paper makes an in-depth report on the green maintenance base of Liquidambar formosana Hance in Zunyi, Guizhou Expressway Group.，Southern road machine equipment appeared from many angles.。It is worth mentioning that，The base is equipped with a set of Nanfang Road Machine.RAPAggregate recycling equipment，A set of Nanfang Road Machinery 2000 quick-moving integral asphalt mixture mixing equipment，Mainly carry out oil stone stripping、Native mixing system、Recycling system and other formats，The completion of the base will strongly promote the low-carbon and high-quality development of the whole industry chain of green recycling and low-carbon maintenance of local highways in Guizhou.。The following is the original report.，Part of the content has been deleted.。What color can an asphalt road have but black?? In recent years，Guizhou High Speed Group Let the Dark Asphalt Road“ Color ”No longer single。Green Maintenance Base of Liquidambar formosana in Zunyi，Pavement milled with old material、Some waste products are treated by new technology.，Become a new material for pavement maintenance，Paint the dark asphalt road.”Low-carbon and environmentally friendly“Green”。AtS55 There is an expressway maintenance base in Baimao section of Renwang Expressway—Guizhou High Speed Group Zunyi Liquidambar formosana Green Maintenance Base，Walk into the base，The first thing you see is standing in the middle of the base.RAPRefined treatment of recycled materials、Reclaimed integral asphalt mixing plantWait for the equipment。According to Wang Shufei, the head of Liquidambar formosana Green Maintenance Base.，The base is the first green low-carbon recycling and maintenance base in Guizhou.。
