Jiangsu Zhenjiang: "Black Technology" helps road maintenance

Recently, the Zhenjiang Transportation Highway Department held an on -site observation meeting on site on the site of local thermal regeneration prevention and maintenance projects on National Highway Prevention and Maintenance Demonstration Demonstration Road, conducted in -depth modernization demonstration actions of road surface surfaces in the city, deepened the "Zhen · Maintenance" brand construction, promoted the establishment of quality engineering creation Essence

"The local thermal regeneration units are currently the most advanced asphalt pavement on -site thermal regeneration construction equipment in the world. This is the second time we use this technology to operate." Ding Wensheng, chief of the maintenance department of the Municipal Highway Business Development Center The operation, the construction speed reaches 3-5 meters/minute, and completes the functions of the surface heating, loose, compound, paved, flat, and forming new road surfaces on the surface of the surface damaged pavement. "The use of this technology has greatly improved the construction efficiency compared to the traditional technology, shortening the construction period."

It is understood that, as a technical application of "circular economy, low -carbon economy", the local thermal regeneration technology combines asphalt pavement pre -care and regeneration technology, which can restore the paceing performance of the original asphalt pavement, and 100%recycled the original asphalt. The old pavement materials realize the re -use of the original pavement materials, save a lot of material resources and funds, and effectively reduce the amount of carbon dioxide emissions, avoid environmental pollution, and achieve sustainable development of highway maintenance.

"This technology not only realizes the reuse of 100%cycle of the original pavement asphalt mixture, but does not produce dust and waste. Traffic can be opened 2-3 hours after construction, which effectively reduces the interference of traffic." Said on-site technicians. (Source: Xue Miao, Zhenjiang City Transportation Bureau)
