So far，The total mileage of highways in China has reached 5.28 million kilometers.，Our country's highway enterprise also transits from the earlier period construction stage to the maintenance stage.，How to reasonably and efficiently recycle the huge waste asphalt mixture produced by road maintenance every year?，It has become a key issue for the relevant industries at present.。In addition，Due to the traditional pavement structure with strong base and thin surface,，The shrinkage cracking of the base course and the reflective cracking of the asphalt pavement caused by the shrinkage cracking are common.，And because of the traffic pressure nowadays.，Traffic is heavy，Cracking can not be dealt with timely and effectively，When the pavement performance is degraded to a certain extent，The pavement has to be repaired or even rebuilt as a whole.，This undoubtedly adds more cost input.。

 

Common Asphalt Concrete Pavement Diseases and Waste Asphalt Mixtur

Continuous cold regeneration equipment（Technology）Came into being，The waste asphalt mixture 100 can be realized%Recycling，And the advantages brought by the process characteristic，It can effectively improve the strength of the pavement after paving.，Inhibit the occurrence of cracks and other pavement diseases。

In fact, as early as 2014.，Deji Machinery has started the research of warm mix asphalt.，It also cooperated with the Highway Science Research Institute of the Ministry of Transport to develop an intermittent asphalt foaming device.（Patent No：ZL 2014 1 0066319.4），After that, in the asphalt mixing plant,（Including regeneration）It is widely used in a complete set.。

Nowadays，In order to meet the technical needs of new areas,，In 2021, Deji Machinery once again cooperated with the Highway Science Research Institute of the Ministry of Transport in research and development.，It has been verified by a large number of engineering practices.，A new type of continuous asphalt foaming device is introduced.(Patent No：ZL 2022 2 0853100.9)，At present, it has been successfully applied to various brands of equipment.。For example, emulsified asphalt equipment was installed in a water stabilization station in Jilin this year.，Transformed into continuous cold regeneration equipment，The trial production was successful on May 14, 2023.。

The continuous cold recycling technology has the following advantages：

Economical and intensive use of old road materials，And that utilization rate of the recycle materials is high，Remarkable effect of energy saving and consumption reduction in normal temperature mixing；

Aving the consumption of primary aggregate crushed stones、Reduce excessive mining of mine rock；

Due to the process characteristics of good wrapping property of foamed asphalt and the like,，And can effectively prolong that service life of the road.；

High Utilization Rate of Waste Asphalt Mixture to Reduce Cost of Engineering Material，Greatly reduce the total investment and production and construction costs of the project；

Continuous production guarantees continuous construction、The output is large，Further improve the construction quality，Better ensure the quality and workability of the front construction；

And that applicability is strong，Applicable to various types of water-stabilized mixing station；

Now，Low carbon、Emission reduction、Circulation has become the strategic development trend of all walks of life.，Other than that，Warm mix technology is accompanied by its high efficiency、High quality、Advantages of low cost，It is bound to be widely used in pavement construction and maintenance industry.，Deji Machinery Association has been adhering to the concept that technological innovation is the driving force of enterprise development.，Continuously dig deep into technological innovation，Continuous contribution to road green construction，Bring more advanced for the users of Deji Machinery、More innovative equipment to meet market demand，And comprehensive overall solution。
