Recently，The first domestic Wittgen new cold in-plant recycling equipment KMA 240i Officially delivered to Shaanxi Green Shengtai Environmental Protection Technology Engineering Co., Ltd.，It has been successfully put into production and applied to the company's road major and medium repair project in Qimen County, Huangshan, Anhui Province.，Through the application of cold recycling of plant-mixed foamed asphalt, the project can improve the reuse rate of old pavement materials.。
Since its debut at the BMW show in Germany in 2022，Wittgen KMA 240i The new type of cold in-plant recycling equipment has excellent mixing performance.、Flexible and convenient transfer deployment、Operating economy, low carbon and other advantages，It has attracted much attention in the industry。The cold mixture produced by this equipment can be used immediately.，It can be ideally used for the construction of different types of base pavement.。
Except for water-stabilized base course (CTB) And roll compacted concrete (RCC) Material，The equipment can also produce asphalt stabilized base materials.（By emulsify asphalt or foamed asphalt）。These different cold mixes have a wide range of uses.，Include：Highway construction、Construction of common roads and paths and parking lots or industrial areas。
High yield：20 tons of cold recycled material is produced every five minutes
The equipment is advanced in technology.，Inherited from the previous model KMA 220(i) All the advantages of，It is equipped with better mixing performance and cement metering system.。The system can realize automatic self-calibration by static weighing.。Equipment mixing capacity up to 240 t/h， It can fill a load of 20 every five minutes. t The Truck。So，Can complete 1400 per day m Long、4 m Wide、15 cm Thick cement stabilized base or asphalt stabilized base pavement。Thanks to an efficient sound-proof enclosure，Its noise emission is very low.。Diesel engines operate very economically，One tank of diesel can last for two days.。
Cold plant-mix regeneration：Environmental protection、Economy、Has wide application
At the same time，Wittgen KMA The mobile plant cold recycling equipment is mounted on a flatbed semi-trailer and equipped with an independent engine.，Efficient transition、Quick and easy deployment。The side discharge belt can swing up to 55 degrees to each sides° Convenient loading and stacking。In practical application, the problem of construction efficiency under the condition that the mixing station is too far away or the site can not complete the recycling construction at one time is solved.，Save transportation time and cost for the project。
In terms of green and low carbon，Thanks to Wirtgen's mature and efficient cold in-place recycling technology，Wittgen KMA 240(i) Cold in-plant recycling equipment CO₂ Emissions reduced by 70 percent%，Cooperate with low running noise volume，Ideal to meet urban construction standards。
The first show on the construction site：Customer satisfaction with production performance

·Project name：Road reconstruction and upgrading of urban and rural garbage transportation links in Qimen County
·Project location：Qimen County, Huangshan, Anhui G237 Main line and branch line merging section
·Application：Cold regeneration of plant-mixed foamed asphalt
·Project overview：The section from the connecting line to the urban area was upgraded in 2014., Asphalt pavement is adopted。This route has become the main channel for urban garbage transportation.，The volume of traffic is increasing rapidly，Therefore, it is under tremendous traffic pressure.。Most of the road sections have cracks.、Cracking、Subsidence、Rut、Repair、Loose and other diseases。
Displayed from pavement condition assessment results and coring results，The coring of the upper base course of most sections is complete.，The lower base course is loose，The surface layer of the two lanes in the middle of the main line is seriously damaged.，The surface layer of the outer two lanes has less diseases.。 It is proposed to upgrade the original road through project reconstruction to realize widening and reconstruction.，The north half is the original pavement reinforcement design.。
·Application：The pavement maintenance scheme for the two lanes in the middle of the main line is full-depth cold in-place recycling.，Restore the structural strength of pavement；The outer two lanes and the branch line are functionally repaired.（Medium repair），Through KMA 240i The cold recycling method of plant-mixed foamed asphalt is to reuse the old asphalt pavement materials which are not suitable for cold recycling on the discontinuous road section and the old asphalt pavement materials which are milled and recycled in advance in the overhaul section nearby the construction site.。
Effect of Pavement Structure Surface after Plant Mixing and Cold Recycling
Customer testimonials
On the day of trial production, the highest production capacity reached 280. t/Hour。Efficient output can effectively improve the recycling rate of old materials throughout the project.，Further reduce natural resource consumption for the project，Cost and time savings。
By virtue of the economy、Efficient、Safe、Environmental protection equipment advantage，Wittgen KMA 240i Plant mixing cold recycling equipment has won the favor of the management of many companies, including Chairman Ke Weiping.，This is also followed by the purchase of 3 sets. W 380 CR / W 240 CR After cold in-place regeneration unit，The fourth Wittgen cold recycling equipment introduced by Shaanxi Green Shengtai Environmental Protection Technology Engineering Co., Ltd.，Greatly expanded the company's ability to cope with road maintenance, recycling and disposal means and multi-scenario adaptability。
Xiaowei will bring you in the next issue.Interview with Ke Weiping, Chairman of Shaanxi Green Shengtai Environmental Technology Engineering Co., Ltd.，Listen to the man who dares to innovate，Dedicated to green road maintenance doer's unique insights and use experience of Wirtgen Group's pavement cold recycling equipment，Please continue to pay attention to Wittgen's official account in China.。
