瀝青混凝土路面現(xiàn)場冷再生的定義

Definition of cold recycling on site of Asphalt Concrete Pavement

現(xiàn)在公路建設(shè)慢慢步出高峰期，隨之而來的必定是養(yǎng)護和改建的高潮期，廢舊路面材料的再生利用成為主要問題之一。廢舊瀝青路面材料的再生技術(shù)在發(fā)達國家已受到普遍重視，被納入可持續(xù)發(fā)展的范疇，并得到廣泛應(yīng)用。

Now the highway construction is slowly stepping out of the peak period, which must be followed by the climax of maintenance and reconstruction. The recycling of waste pavement materials has become one of the main problems. The recycling technology of waste asphalt pavement materials has been widely valued in developed countries, and has been included in the scope of sustainable development, and has been widely used.

瀝青混凝土路面的現(xiàn)場冷再生是指利用舊瀝青混凝土路面材料( 包括面層材料和部分基層材料) 進行破碎加工，需要時加入部分新骨料或細集料，按比例加入一定劑量的添加劑( 水泥、石灰、粉煤灰、泡沫瀝青和乳化瀝青等) 和適量的水，在自然的環(huán)境溫度下連續(xù)地完成材料的銑刨、破碎、添加、拌和、攤鋪及壓實成型的作業(yè)過程，并重新形成結(jié)構(gòu)層的一種工藝方法。再生后，視公路等級的不同，在再生層上加鋪瀝青混凝土面層。

The site cold recycling of asphalt concrete pavement is the use of old asphalt concrete pavement materials (including surface materials and some basic materials) for crushing and processing. Some new aggregates or fine aggregates are added when required, and a certain proportion of additives (cement, lime, fly ash, foamed asphalt and emulsified asphalt) and proper amount of water are added proportionally. It is a process to continuously complete the milling, crushing, adding, mixing, paving and compaction of materials under natural ambient temperature, and to re form the structural layer. After regeneration, depending on the highway grade, asphalt concrete surface layer is paved on the regeneration layer.
