近年來，更有利于資源保護(hù)的技術(shù)得到越來越多的關(guān)注。在筑養(yǎng)路領(lǐng)域，經(jīng)濟(jì)環(huán)保的冷再生施工技術(shù)正風(fēng)靡全球。

　　In recent years, technologies that are more conducive to resource conservation have received increasing attention. In the field of road construction and maintenance, economically and environmentally friendly cold recycling construction technology is becoming popular worldwide.

　　頻繁受到重型或持久荷載沖擊的道路，路基會(huì)出現(xiàn)損壞的跡象。如果對受損路基進(jìn)行修復(fù)，則整個(gè)路面結(jié)構(gòu)都需要維修。使用冷再生工藝，可將原有材料 100% 的回收并被重新利用，處理過程成本較低，因此，冷再生工藝是一種即經(jīng)濟(jì)又環(huán)保的理想選擇。作為冷再生技術(shù)的先驅(qū)，在過去的 30 年里，維特根品牌在完善該工藝中起到了關(guān)鍵性的作用，并且為冷再生產(chǎn)品的發(fā)展做出了不懈努力。

　　Roads that are frequently impacted by heavy or persistent loads may show signs of damage to the roadbed. If the damaged roadbed is repaired, the entire pavement structure needs to be repaired. By using cold recycling technology, 100% of the original materials can be recovered and reused, with low processing costs. Therefore, cold recycling technology is an ideal choice that is both economical and environmentally friendly. As a pioneer in cold recycling technology, the Wittgen brand has played a crucial role in improving this process over the past 30 years and has made unremitting efforts for the development of cold recycling products.

　　WR 系列輪式冷再生機(jī)

　　WR series wheel cold regeneration machine

　　維特根品牌為客戶提供了三款輪式冷再生機(jī)：WR 200，WR 240 和 WR 250。配備強(qiáng)勁的銑刨及拌合轉(zhuǎn)子以及超現(xiàn)代化的噴灑裝置，這三款設(shè)備均能夠一次性完成銑刨瀝青路面并破碎、以精準(zhǔn)計(jì)量噴灑粘結(jié)劑和水、以及進(jìn)行拌合這一系列工序。

　　The Wittgen brand offers customers three types of wheeled cold regeneration machines: WR 200, WR 240, and WR 250. Equipped with powerful milling and mixing rotors, as well as ultra modern spraying devices, all three devices can complete the milling and crushing of asphalt pavement in one go, accurately measure the spraying of binder and water, and carry out a series of mixing processes.

　　履帶式冷再生機(jī)以及新工藝

　　Crawler type cold recycling machine and new technology

　　維特根品牌還提供了兩款履帶式冷再生機(jī)：2200 CR 和 3800 CR，這兩款設(shè)備的工作寬度分別為 2.2 m 和 3.8 m。與 WR 系列設(shè)備一樣，它們可就地再生瀝青路面。這兩款設(shè)備還能使用配備夯錘和布料攪龍的集成式、無級可調(diào)的福格勒熨平板，以便對再生瀝青混合料進(jìn)行預(yù)壓實(shí)。

　　The Wittgen brand also offers two track type cold recycling machines: 2200 CR and 3800 CR, with working widths of 2.2 m and 3.8 m respectively. Like the WR series equipment, they can regenerate asphalt pavement on site. These two devices can also use an integrated, infinitely adjustable Vogler ironing board equipped with a rammer and fabric mixer to pre compact recycled asphalt mixtures.

　　除了以傳統(tǒng)的上切模式進(jìn)行冷再生施工之外，這兩款設(shè)備還能以維特根品牌最新研發(fā)的下切模式施工，從而優(yōu)化冷再生工藝。在這種模式下，再生的材料通過后收料皮帶直接輸送至攤鋪機(jī)，然后被立即攤鋪并預(yù)壓，最后，使用壓路機(jī)進(jìn)行終壓實(shí)。尤其對于破損嚴(yán)重、松散的瀝青路面，采用下切模式施工可得到理想的材料級配控制。

　　In addition to using the traditional top cutting mode for cold recycling construction, these two devices can also use the latest developed bottom cutting mode of the Wittgen brand for construction, thereby optimizing the cold recycling process. In this mode, the recycled material is directly transported to the paver through the rear receiving belt, and then immediately spread and preloaded. Finally, the roller is used for final compaction. Especially for severely damaged and loose asphalt pavements, using the downward cutting mode for construction can achieve ideal material grading control.

　　維特根 KMA 220 廠拌冷再生設(shè)備

　　Wittgen KMA 220 Factory Cold Recycling Equipment

　　維特根 KMA 220 的移動(dòng)式理念使其在施工現(xiàn)場附近可快速布置并且高效拌合。該廠拌設(shè)備從各方面來講都非常環(huán)保：生產(chǎn)混合料的基礎(chǔ)材料無需干燥或加熱，這就意味著大大節(jié)省了能源和成本；往來混合料生產(chǎn)地點(diǎn)和施工現(xiàn)場之間的耗時(shí)的卡車運(yùn)輸被最大限度地減少，從而實(shí)現(xiàn)了節(jié)能減排。

　　The mobile concept of the Wirtgen KMA 220 allows for quick deployment and efficient mixing near construction sites. The mixing equipment in this factory is very environmentally friendly in all aspects: the basic materials for producing the mixture do not require drying or heating, which means significant energy and cost savings; The time-consuming truck transportation between the mixed material production site and the construction site is minimized, thereby achieving energy conservation and emission reduction.
