冷再生機(jī)施工的經(jīng)濟(jì)效益和社會效益是什么呢？
What are the economic and social benefits of cold regenerator construction?
瀝青路面的再生，可以地處理瀝青路面維修時產(chǎn)生的廢料，限度地利用資源和保護(hù)環(huán)境。
The recycling of asphalt pavement can effectively deal with the waste generated during asphalt pavement maintenance, make full use of resources and protect the environment.
（1）冷再生機(jī)可循環(huán)利用舊路面材料中的瀝青，減少公路工程對新的瀝青資源的占用，對于緩和我國作為石油進(jìn)口大國（我國也是路用瀝青進(jìn)口大國）的資源壓力尤其重要；
(1) The cold recycling machine can recycle the asphalt in the old pavement materials and reduce the occupation of new asphalt resources by highway engineering, which is particularly important to alleviate the resource pressure of China as a large oil importer (China is also a large road asphalt importer);
（2）可循環(huán)利用舊路面的砂石材料，冷再生機(jī)減少公路工程中對新砂石材料資源的占用和消耗，減少開采砂、石料對環(huán)境造成的破壞；
(2) The sand and gravel materials of the old pavement can be recycled, and the cold recycling machine can reduce the occupation and consumption of new sand and gravel materials in highway engineering, and reduce the damage to the environment caused by sand and stone mining;
（3）由于瀝青的不可降解性，冷再生機(jī)舊瀝青路面的再生，杜絕了丟棄和填埋舊瀝青混合料所產(chǎn)生的直接污染，保護(hù)了生態(tài)環(huán)境；
(3) Due to the non degradability of asphalt, the regeneration of old asphalt pavement by cold regenerator eliminates the direct pollution caused by discarding and landfill of old asphalt mixture and protects the ecological environment;
（4）冷再生機(jī)舊瀝青路面的再生還有直接的經(jīng)濟(jì)效益，回收舊料及加工處理成本十分低廉，每再生利用1t舊瀝青回收廢料，至少可節(jié)省相當(dāng)于0．8t新瀝青混合料所需的材料費用，冷再生機(jī)價格，可大大降低公路工程維修和改建的造價。
(4) The recycling of old asphalt pavement by cold recycling machine also has direct economic benefits. The cost of recycling old materials and processing is very low. Each recycling 1t of old asphalt recycling waste can save at least the material cost equivalent to 0.8t of new asphalt mixture. The price of cold recycling machine can greatly reduce the cost of highway engineering maintenance and reconstruction.
冷再生機(jī)技術(shù)要點：含水量對摻加水泥的瀝青混合料有很大的影響，當(dāng)含水量不足時，水泥不能在混合料中完全水化和水解，發(fā)揮不了水泥對混合料的穩(wěn)定作用，影響強(qiáng)度的形成，含水量偏大會有水分流出，水泥的成分隨水流走，導(dǎo)致抗壓強(qiáng)度降低;含水量過大還會造成摻加水泥的瀝青混合料的干縮問題。
Key points of cold regeneration technology: the water content has a great impact on the asphalt mixture mixed with cement. When the water content is insufficient, the cement can not be fully hydrated and hydrolyzed in the mixture, can not play the stabilizing role of cement on the mixture, and affect the formation of strength. The water content tends to flow out, and the components of cement go with the water flow, resulting in the reduction of compressive strength; Excessive water content will also cause the dry shrinkage of asphalt mixture mixed with cement.
