Current situation of domestic asphalt pavement
In China, most of the first grade and second-class highways are of asphalt pavement structure, and the design life is generally 10 to 15 years, and they usually need to be repaired and overhauled once in 5 to 10 years.
During the "Thirteenth Five-Year Plan" period from 2015 to 2020, China's expressways would produce 50 million tons of old mixture every year. The birth of hot mix plant recycling technology is to transport the old asphalt pavement back to the asphalt mixing plant after digging, then shred and crush intensively. According to the quality requirements of different layers of the pavement, matching ratio design is carried out to determine the proportion of the old asphalt mixture; recycling agent, new asphalt material, new aggregate, etc. are remixed into new mixture in a certain proportion in the mixer so as to obtain excellent new asphalt mixture and build recycled asphalt pavement. Tens of billions of resources can be saved for the country every year by means of hot recycling.
D&G Machinery is born for road construction. Driven by innovation, D&G is focusing on environmental protection and assisting the reuse of highway waste asphalt. The integrated hot-recycling asphalt plant that was introduced to the market through technical transformation and independent research and development in 2014 is not only the only one in China, but also the first one in the world. The integrated hot recycling plant makes a brilliant appearance on the world stage with its unique charm.
The only integrated hot recycling asphalt plant in China

Abandon the traditional idea of piecing together the "regenerative function", redesign the whole mixing plant to increase the capacity of the mixer by 30-40%. Even if the mixing time is extended, the plant output can be guaranteed. Regeneration regarded as the "standard configuration" of the mixing equipment becomes an indispensable part of the whole set of plant, so as to get rid of a series of defects such as higher height and complexity of traditional mixing plant, easy bonding of materials, reduction in production output, aging, extension of time, etc. The adding proportion of old materials can reach more than 50% by means of systematic solutions. This asphalt mixing plant，said to be born for regeneration, is a real recycling asphalt mixing plant.
The recycling technology of the old mixture not only saves the project cost, reduces the consumption of energy resources, but also avoids the land pollution and environmental damage caused by the idle old asphalt. D&G Machinery uses technology to protect the green hills and clear waters of the global village!
