Fine Separation Nanfang Road Machine Helps Gansu Open the Road of Regeneration of Asphalt Milling Material

May 14, 2024

Recently,Gansu Highway Development Group Co., Ltd.To implement the concept of sustainable development and circular economy,Wholly state-owned enterprises under its flagChangjie Subsidiary of Gansu Changtong Highway Maintenance Technology Co., Ltd.Introduce the first one in Northwest ChinaRAPRAggregate recycling equipment,On April 30, 2024, the equipment commissioning work was completed in Baiyin East Material Yard.,Officially start production。


A large number of asphalt milling materials produced in the process of highway maintenance,Random stacking or discarding not only takes up land,There are environmental pollution problems,But also cause that waste of non-renewable resources such as stone and asphalt in the waste material.。At present,The recycling of asphalt milling materials is mainly through the direct mixing of new materials and old materials.,However, the quality of the recycled mixture produced is poor、Low utilization rate of old materials。
To reduce the storage pressure of asphalt milling material,Reduce resource consumption and environmental pollution。2024,Introduction of Nanfang Road Machinery by Baiyin Highway Development CenterRAPRAggregate recycling equipment,Carry out fine separation on that asphalt milling material,Promote the innovation of maintenance materials、Transformation of maintenance mode、Improvement of curing operation, etc.,Break through that bottleneck of recycling of asphalt mil materials in the traditional highway maintenance field,Exploring high efficiency and low carbon、Resource conservation、A key step has been taken in the new road of green cycle highway maintenance.。


Nanfang Road MachineRAPRAggregate recycling equipment is crushed、Stripping、Fine separation processes such as screening,Change waste asphalt milling material into valuable,Asphalt pavement milling materials can be divided into 3-Graded material of grade 5,In particular, achievableRAPFine aggregate 0-3mm、3-5mmFine separation。The equipment can absorb asphalt waste in large proportion.,Aving a large amount of aggregate and asphalt resource,Reatly reducing production cost,At the same time, centralized dust removal technology is adopted.,Carry out effective suction on each dust raising point of the equipment,Ensure no dust escape。


SutraRAPRThe asphalt recycled material treated by the aggregate recycling equipment can be completely suitable for high-grade pavement engineering.,Ffectively solve that problems of mix hot regeneration in a plant,RAPQuality Fluctuation of Asphalt Mixture with Excessive Content。RAPAggregate recycling equipment can better control aggregate gradation,The problems of false particle size of old materials and variability of recycled asphalt are basically eliminated.,Effectively solve and improve constraintsRAPKey issues of dosage and performance,Really make the best use of everything。
Future,Gansu Baiyin Highway Development Center will also work closely with Gansu Highway Development Group.,Vigorously develop green cycle low-carbon maintenance technology,Promote the innovation of maintenance materials、Transformation of maintenance mode、Improvement of curing operations。At the same time,Nanfang Road Machinery will also continue to help Baiyin Highway Development Center rely on Baiyin East Material Yard.RAPRAggregate recycling equipment,Break through the bottleneck of recycling of asphalt milling materials in the field of traditional highway maintenance,Promote highway maintenanceGreen and low carbon、Intensive resources、Energy-saving ringBaoDirection of development,Help with practical actions“Double Carbon”The achievement of the goal。
