Asphalt pavement recycling old material（RAP）Is becoming increasingly important to the road construction industry.。This trend is mainly influenced by two factors.。
First, the support of national and local policies.。These regulations or initiatives encourage asphalt mix producers and road construction conTractors to adopt more environmentally friendly solutions。And use environmentally friendly equipment、Technical and material decisions，Will bring them great rewards.。
Two, the situation of the international oil market is not clear.，Affect the cost and availability of key resources。
Be good at usingRAPCompanies will have the opportunity to grow their businesses in the coming years.，Because everything is moving forward.。Anmai and its engineers hope to solve the problem through flexible regeneration technology.，To help customers improve this possibility as much as possible.。
RightRAPTreatment method combined with an effective regeneration system，It is possible to add a high proportion ofRAP。
For asphalt mix producers，RecyclingRAPThe most obvious benefit is the reduced need for virgin asphalt binders and aggregates.。RAPThe cost can be saved，Solve the shortage of materials，Or keep the plant running when the price of production materials is high.。However，This will not happen overnight.，Careful and specific work is required。Suitable mixture gradation，Avoid damage to asphalt during regeneration，EnhanceRAPQuality of screening and storage……These factors will affect the new mixture.RAPAdd scale。
If you don't handle it correctly beforehand,RAP，Or the Asphalt Mixing Plant can not control the regeneration process well.，The quality of the final asphalt mixture will be affected.。
Want to get higherRAPUtilization，The first step is not to mix the old layers of the milled asphalt together，Because of their different gradations。Over the years，RAPBeen dealt with like this all the time.，As a result, there was no chance to return to the asphalt surface.，Even shipped to Landfills.。
Anmai hopes to achieve true recycling.，I.e. The recovered material is added to the new mix，Finally, it is reused for its original purpose.。
The milled old asphalt pavement is transported to the factory by Truck.，It is then correctly sieved into a pile of several sizes。The asphalt mixture producer must try to find out the gradation of the material.，Filler and bitumen content，And how toRAPChoose the right additives for asphalt, etc.。Except for not mixing the materials together.，Overwrite correctlyRAPWindrows are an effective way to reduce moisture.。Amway helps customers find better storage solutions with engineers in the field。
When you really understandRAPThese aspects of，Combined with Anmai's regeneration technology，Then you'll be one step ahead.RAPHigh utilization rate，And that production cost is save。
RAPOne of the real challenges is the heating problem.。In order to reuseRAP，It must be heated，And the speed of heating is crucial.。
Add recycled material in the same drying drum，It is directly heated and mixed with the primary aggregate，This can only makeRAPThe proportion of additions reaches a limited level.。In this case,，Due to rapid heating，It is common for the quality and performance of asphalt to be permanently impaired by oxidation。In addition，The asphalt will become sticky.，Difficult to handle in an ordinary drying drum。
Heat recovery in dedicated regeneration drum，Can be more effectivelyRAPGradually warming up。But how can we reach higher?RAPWhat about utilization?？Anmai offers 4 to be added in the mixRAPThe method of，They can be combined in different forms in batch and continuous Asphalt Mixing Plants。
01.
RAPCold material is directly added into the mixing cylinder。All types of mixing plants can be retrofitted，RAPThe utilization rate is 25%-30%，Concrete number and production system、The stirring temperature is related to the water content.。
02.
RAPThe cold charge is added through the intermediate ring of the drying drum。Can achieve 40%YesRAPUtilization，Can be used with cold recovery system，Provides greater flexibility during plant operation。
03.
RAPThe cold charge passes throughRAH60 Parallel Rollers Add。Can achieve 60%YesRAPUtilization，It also integrates the professional operation experience of many Anmai mixing stations from all over the world.。
04.
RAPThe cold charge passes throughRAH100 counterflow drum addition。No thermal radiation，Right, evenlyRAPHeating，Less damage to asphalt，TheoreticallyRAPUp to 100 percent%。
Anmai understands that not every customer is looking for 100%YesRAPUtilization and ready for it，Some may need variety and flexibility.。Anmai's regeneration system can be modified，Suitable for standard type of Asphalt Mixing Plant。In addition，We will provide technical support and training for our customers.，Help them get the most out of their mixing stations andas1 Control system。
With the help ofas1 Additional functions of the control system——Add dynamicallyRAPModule（That isRAD），The operator can change the slide continuously during productionRAPPercentage；PIPThe module allows operators and equipment managers to、Energy consumption、Fuel consumption、RAPUse and other mixing station information to send directly to their smart mobile devices。
All in all，Everything depends on the customer's needs.。If they follow the code,，Do it wellRAPPreparations for，Anmai's recycling technology and equipment can help them achieve the ideal number.。
