It is widely applied in expressway construction with stable use quality.To year ends 2012, there have been more than 400 ten thousand public affairs in China
In highway be open to the traffic, the super highway road surface, secondary super highway road surface wherein based on asphalt concrete pavement just have 9.5 ten thousand
Km is only second to the U.S., occupies the second in the world, it is seen that asphalt concrete pavement is the primary structure shape of Chinese Higher highway pavement
Formula.China started to build the highway of bituminous paving the 1980s, and bituminous paving general projected life is 15
Year --- 20 years.Therefore, the bituminous paving highway that China then builds up has been enter into big or middle repair successively at the bottom of the nineties
Phase, however, the hot in-place recycling technology of waste asphalt concrete is not yet grasped in China by full maturity at present.
Asphalt surface hot reproduction method has hot in-plant reclaimed and two kinds of in-situ heat regeneration.Hot in-plant reclaimed is exactly by waste and old drip
Green mixture transports to batching plant, then carries out break process, adds a certain proportion of regenerative agent, new gathers materials or new pitch mixture etc.
It is fully mixed and stirred, obtains function admirable, meet the Recycled Asphalt Pavement of pavement performance, and be compacted into again new after regeneration
Bituminous paving.Sheet pavement in-situ heat regeneration is exactly that the bituminous paving scene of carrying out damaged is added using in-situ heat regeneration device
The waste asphalt concrete of softening is carried out milling, then adds the new pitch mixture and pitch centainly matched on the spot again by heat
Regenerative agent etc., the heat by on-site heat regeneration equipment mixes and stirs, paves and pressing and the multiple tracks working procedure such as rolls, disposable to realize pair
Impaired bituminous paving carries out the technology of reparative regeneration.In-situ heat regeneration with its flow through gathering, process is simple and pavement preservation quality
The advantages that good, is widely used in waste asphalt pavement is safeguarded and is conserved.
The correlative study starting of China's Hot Reclamation Technology in Place for Asphalt Pavement than later, into 21 century after just gradually obtain
Extensive concern with domestic more asphalt surface hot reproduction equipment of Introduced From Abroad successively, is transformed it, and in bituminous paving
Maintenance in succeed application, Hot Reclamation Technology in Place for Asphalt Pavement just gradually gets the nod.Sheet pavement in-situ heat regeneration
Technology is still in infancy in China, compared with other developed countries, need to be furtherd investigate.
Therefore, it is necessary to a kind of asphalt road surface by microwave heating in-situ heat regeneration devices to conserve bituminous paving.At present, on road surface
The microwave heating equipment used can not realize the spatial position control to heating unit, some complex road surfaces are difficult to soon mostly
Prompt heat, and the efficiency of heating surface is not high.Therefore, it is necessary in feelings such as shape, the sizes being destroyed in view of bituminous paving
Under the premise of condition, asphalt road surface by microwave heating in-situ heat regeneration device is designed.Meanwhile to prevent magnetron from coming out
Electromagnetic wave generate leakage, need consider the electromagnetic wave leaked out is shielded, and this screening arrangement should as possible just
Prompt is mounted on asphalt road surface by microwave heating in-situ heat regeneration device.
