冷再生机施工的经济效益和社会效益是什么呢？
What are the economic and social benefits of cold regenerator construction?
沥青路面的再生，可以地处理沥青路面维修时产生的废料，限度地利用资源和保护环境。
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）冷再生机可循环利用旧路面材料中的沥青，减少公路工程对新的沥青资源的占用，对于缓和我国作为石油进口大国（我国也是路用沥青进口大国）的资源压力尤其重要；
(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）可循环利用旧路面的砂石材料，冷再生机减少公路工程中对新砂石材料资源的占用和消耗，减少开采砂、石料对环境造成的破坏；
(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）由于沥青的不可降解性，冷再生机旧沥青路面的再生，杜绝了丢弃和填埋旧沥青混合料所产生的直接污染，保护了生态环境；
(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）冷再生机旧沥青路面的再生还有直接的经济效益，回收旧料及加工处理成本十分低廉，每再生利用1t旧沥青回收废料，至少可节省相当于0．8t新沥青混合料所需的材料费用，冷再生机价格，可大大降低公路工程维修和改建的造价。
(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.
冷再生机技术要点：含水量对掺加水泥的沥青混合料有很大的影响，当含水量不足时，水泥不能在混合料中完全水化和水解，发挥不了水泥对混合料的稳定作用，影响强度的形成，含水量偏大会有水分流出，水泥的成分随水流走，导致抗压强度降低;含水量过大还会造成掺加水泥的沥青混合料的干缩问题。
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.
