冷再生机对沥青路面施工要领!

来源:https://www.sddhfjx.com/ 日期:2021-02-22
冷再生机沥青路面的再生和回收利用大致可以分为厂拌热再生、厂拌冷再生、就地热再生、就地冷再生以及全厚式就地冷再生5种,它们各有所长,适用于不同的路面病害。
The recycling and recycling of cold recycling machine asphalt pavement can be roughly divided into plant hot recycling, plant cold recycling, on-site hot recycling, on-site cold recycling and full thickness on-site cold recycling.
全厚式就地冷再生出租指是由一个机组连续地完成对旧路面的铣刨、破碎、新材料添加、新旧材料拌合、摊铺及压实,从而形成新基层的一体化再生施工工艺。一般再生处理深度为15-30cm,下深可达30-50cm。
Full thickness on-site cold recycling refers to the continuous completion of milling, crushing, adding new materials, mixing, paving and compaction of old and new materials on the old pavement by one unit, so as to form the integrated recycling construction technology of new base. Generally, the depth of regeneration treatment is 15-30cm, and the depth can reach 30-50cm.

由于全部利用了旧的铺层材料,减少了公路维修时就铺层材料的挖除、运输、废置和部分新材料的购置费用,冷再生机租赁大大降低成本。一般可以降低成本20%~40%,厚度越深,降低成本越多。主材:水泥、水、少量新骨料、石灰(早强剂)等。采用水泥为结合料取材方便、价格便宜、快速恢复强度,且类似半刚性基层,技术成熟。
As all the old paving materials are used, the excavation, transportation, waste disposal of paving materials and the purchase cost of some new materials during highway maintenance are reduced, and the rental cost of cold recycling machine is greatly reduced. Generally, the cost can be reduced by 20% - 40%. The deeper the thickness is, the more the cost will be reduced. Main materials: cement, water, a small amount of new aggregate, lime (early strength agent), etc. Using cement as binder is convenient, cheap and quick to recover strength, and similar to semi-rigid base, the technology is mature.
