采用傳統(tǒng)的施工工藝對公路進行養(yǎng)護，不僅增加了廢料外運成本，還會因為處理不當(dāng)而造成環(huán)境污染。而采用廢舊瀝青路面材料再生技術(shù)，不僅可以避免廢棄材料堆放對土地的占用和環(huán)境的污染，還可以減少對石料、瀝青、水泥的需求，降低筑養(yǎng)路成本。就地冷再生作為一種較為成熟的綠色公路維修改造技術(shù)，具有簡化施工工藝、節(jié)約材料、縮短工期和降低成本等多個優(yōu)勢，已經(jīng)廣泛應(yīng)用于國內(nèi)多種道路的維修改造中。目前，國內(nèi)市場上就地冷再生機(以下簡稱冷再生機)品牌眾多，既有國外知名品牌維特根、寶馬格、卡特彼勒和特雷克斯，又有國內(nèi)品牌徐工筑路、山東德工、鞍山森遠(yuǎn)等。那么這些品牌的冷再生機使用狀況如何？它們都有哪些優(yōu)勢和不足？能否與目前的施工工藝完全適應(yīng)？設(shè)備廠商應(yīng)該如何對其進行改進與提升以適應(yīng)市場需求？對此我們邀請幾位專家對此進行探討。

Using traditional construction technology for highway maintenance not only increases the cost of waste transportation, but also causes environmental pollution due to improper treatment. The recycling technology of waste asphalt pavement materials can not only avoid the land occupation and environmental pollution caused by the stacking of waste materials, but also reduce the demand for stone, asphalt and cement, and reduce the cost of road construction and maintenance. As a mature green highway maintenance and reconstruction technology, in situ cold recycling has many advantages, such as simplifying construction technology, saving materials, shortening construction period and reducing cost, and has been widely used in domestic road maintenance and reconstruction. At present, there are many brands of on-site cold recycling machine (hereinafter referred to as cold recycling machine) in the domestic market, including famous foreign brands wittgens, BMW, caterpillar and Terex, as well as domestic brands Xugong road construction, Shandong Degong, Anshan Senyuan, etc. So how about the use of these brands of cold recycling machine? What are their advantages and disadvantages? Can it fully adapt to the current construction technology? How should equipment manufacturers improve and upgrade them to meet the market demand? We invite several experts to discuss this.

瀝青路面再生技術(shù)如何分類？目前國內(nèi)市場上有哪些品牌就地冷再生機？各品牌市場分布狀況怎樣？產(chǎn)品與服務(wù)口碑如何？

How to classify asphalt pavement recycling technology? What brands of cold in place regenerators are available in the domestic market? What is the market distribution of each brand? What is the reputation of products and services?

瀝青路面冷再生技術(shù)就是在常溫下將舊瀝青路面破碎，與新集料、新粘結(jié)劑等按一定比例拌和成新的混合料，并重新鋪筑于路面的一整套工藝。冷再生技術(shù)可分為廠拌冷再生和就地冷再生2種。就地冷再生是通過大型現(xiàn)場再生設(shè)備對舊路面進行破碎、添加新粘結(jié)劑、拌和、攤鋪的施工工藝。

The cold recycling technology of asphalt pavement is a complete set of technology that the old asphalt pavement is broken at room temperature, mixed with new aggregate and new binder in a certain proportion to form a new mixture, and then re paved on the pavement. Cold recycling technology can be divided into plant mixed cold recycling and in-situ cold recycling. In situ cold recycling is a construction technology of crushing old pavement, adding new binder, mixing and paving by large-scale on-site recycling equipment.
