"The hot-in-place recycling unit is the most advanced asphalt pavement hot-in-place recycling construction equipment in the world. This is the second time we have used this technology for operation." The person in charge of the Maintenance Section of the Municipal Highway Business Development Center introduced that the equipment adopts streamlined operation. , the construction speed reaches 3-5 m/min, and the surface damaged pavement can be heated, loosened, mixed, paved, leveled, and formed into a new pavement at one time to achieve the function of repairing the disease. "Using this technology, the construction efficiency is greatly improved compared with the traditional process, and the construction period is shortened."
It is understood that as a technical application of "circular economy and low-carbon economy", hot-in-place recycling technology combines asphalt pavement pre-maintenance and regeneration technology, which can not only restore the road performance of the original asphalt pavement, but also recycle 100% of the original asphalt. Old pavement materials can realize the reuse of original pavement materials, save a lot of material resources and funds, and can effectively reduce carbon dioxide emissions, avoid environmental pollution, and achieve sustainable development of road maintenance.
"In addition to realizing the recycling of old materials, this technology does not generate dust and waste, and traffic can be opened 2-3 hours after construction, which effectively reduces the interference of maintenance construction on traffic." The on-site technician said.
