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。

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。

Actually，The application technology of asphalt pavement recycled material recycling has been very common in China.，But the application is relatively crude.。Most applications，Simply sift out the coarse、Fine recycled aggregate，Without further refined separation.。To a certain extent,，Reduces the application proportion and occasions of the recycled material，Reduces the performance of the asphalt recycled pavement。

Nanfang Road Machinery hopes to achieve real recycling.，Push outRAPAggregate recycling equipment，Take a physical approach toRAPThe old asphalt and the old aggregate are effectively separated.，RealizationRAPPrecise grading management，Better control of aggregate gradation，Significantly reduce the false particle size phenomenon andRAPMaterial variability，Effectively solve and improve constraintsRAPKey issues of dosage and performance，Really make the best use of everything。

Nanfang Road MachineRAPAggregate recycling equipment can divide asphalt pavement milling materials into 3-Graded material of grade 5，In particular, achievableRAPFine aggregate 0-3mm、3-5mmFine separation。Among，Separated greater than 3mmLow asphalt content in aggregate，Can be added to the asphalt plant by a hot recycling system，Effectively control the gradation of raw materials，Improve the performance of the pavement。The other gear is less than 3mmThe aggregate can be directly fed into the mixing main machine by cold addition.，The sticking of the regeneration roller can be reduced.，Improve the quality of finished mixture，And that consumption of new asphalt is save.。

Via Nanfang Road MachineRAPThe asphalt recycled material treated by the aggregate recycling equipment can be completely suitable for high-grade pavement engineering.，Ffectively solve that problems of plant mix hot regeneration,RAPQuality Fluctuation of Asphalt Mixture with Excessive Content。

Recycling of Waste Asphalt Mixture for Environmental Protection、Save energy、Reducing the cost of the project can bring economic and social benefits.，Nowadays, it is more and more widely used in domestic road construction.，Through the addition proportion of the recycled material、Findings of the research on the adding method，Classification of recycled materials and their application scope、Cost、Quality has a significant impact，The finer the grading，RAPThe higher the mixing ratio。Nanfang Road Machinery Co., Ltd. is a leading enterprise in the field of asphalt recycling，Independently developedRAPAggregate recycling equipment，Greatly improvedRAPStability of aggregate gradation，Large-scale addition can be realized， Really realize the fine separation of recycled asphalt mixture。
