The technology for central plant cold recycling of emulsified asphalt is a set of professional technology of special construction for cold recycling. The technology takes high-quality recycled emulsified asphalt as the binding material, utilizes SLONG® special mixing machinery and is suitable for the rapid maintenance of semi-rigid flexible conversion at the basic level. This technology is a flexible renewable technology that fully coats the old asphalt and the only low-carbon and green technology that has universally achieved 100% old asphalt recycling among all renewable types. This technology is suitable for highway, arterial highway, the renovation of old asphalt pavement of heavy load municipal road, the overhaul, the reconstruction and expansion. No carbon dioxide would be released in the highway construction. The green maintenance, energy conservation and emission reduction would also be ensured by this high and new technology which possesses unique advantage in the adaption to construction and in the economic indicators.
This technology is a key technological project promoted by the Ministry of Transport of People’s Republic of China and is a demonstration project on energy conservation and emission reduction of the Ministry of Transport of People’s Republic of China. As an international - level technology that fills the domestic blanks, this technology has been included into the national promotion catalogue of key energy-saving technologies and is among the second batch of demonstration technologies in energy conservation and emission reduction promoted by the Ministry of Transport of People’s Republic of China. It is also the only technology promoted by the highway sector in the special action called “low carbon traffic, energy conservation and emission reduction” in the areas of automobile, ship, road and port of national transportation industry which is an action jointly researched by the Ministry of Transport and the transportation sector.
