道路施工时使用冷再生机的优点都有哪些

来源:https://www.sddhfjx.com/ 日期:2022-06-24
1、效率高
1. High efficiency
冷再生机施工可一次性完成铣刨、破碎、添加、拌和及摊铺,简化了施工程序,缩短施工工期。
The cold regenerator construction can complete milling, crushing, adding, mixing and paving at one time, simplifying the construction procedure and shortening the construction period.
2、施工质量好
2. Good construction quality
可根据不同道路旧铺层材料的实际情况进行设计,选择不同的添加剂,配比准确,可以保证再生材料的品质和施工质量,形成施工成型厚而均匀的粘结层,从而保证了维修后道路的使用期限。一般冷再生层的集料采用来自原路面结构的铣刨料RAP,其冷再生层的评价主要根据强度控制,强度依路面等级的不同由设计部门确定,7天无侧限抗压强度应达2MPa以上,但对于水泥冷再生来讲,水泥用量一般不应超过6%。
The design can be carried out according to the actual situation of the old paving materials of different roads. Different additives can be selected and the proportion is accurate, which can ensure the quality of recycled materials and construction quality, and form a thick and uniform bonding layer formed during construction, so as to ensure the service life of the road after maintenance. Generally, the aggregate of the cold recycling layer adopts the milled material rap from the original pavement structure. The evaluation of the cold recycling layer is mainly based on the strength control. The strength is determined by the design department according to the different pavement grades. The 7-day unconfined compressive strength should be more than 2MPa, but for the cold recycling of cement, the cement consumption should not exceed 6%.
3、成本低
3. Low cost
由于冷再生层利用的是旧路面的铺层材料,减少了道路维修或改造时旧铺层材料的开挖、运输、废置和新材料的购置,降低了成本,而且冷再生路面厚度越厚,降低的成本就越多。
Because the cold recycled layer uses the paving material of the old pavement, it reduces the excavation, transportation, disposal of the old paving material and the purchase of new materials during road maintenance or reconstruction, and reduces the cost. Moreover, the thicker the cold recycled pavement is, the more the cost will be reduced.
4、受天气条件影响小
4. Little affected by weather conditions
旧地冷再生能够在天气环境不确定的条件下施工,除了在降雨量较大时,一般的阴晴不定的天气,小雨天气,冷再生机均可施工,即使在大雨过后,也可马上恢复施工。
The old land cold regeneration machine can be constructed under the condition of uncertain weather environment. Except in the case of heavy rainfall, the cold regeneration machine can be constructed in general cloudy and sunny weather, light rain weather, and even after heavy rain, the construction can be resumed immediately.
5、具有环保优势
5. Environmental protection advantages
传统的道路维修方法,会产生大量的沥青废料,对环境污染很大,新材料的开采也会造成资源减少和环境的破坏,而冷再生施工工艺,不仅可以节约资源,更有利于环境保护,因此被人们称之为“绿色”施工技术。
Traditional road maintenance methods will produce a large amount of asphalt waste, which will cause great environmental pollution. The exploitation of new materials will also cause resource reduction and environmental damage. Cold regeneration construction technology can not only save resources, but also be more conducive to environmental protection. Therefore, it is called "green" construction technology.
6、对公共交通影响显著减少
6. Significantly reduce the impact on public transport
冷再生工艺施工的特点是工序简单、施工设施少、对交通干扰低,因为它整套设备都可处于同一条车道内,不影响另一条车道车辆的通行,可进行开放式施工,特别适用于交通量大或路宽较窄的道路施工。当道路半幅施工时,另半幅照常开通,大大改善了交通状况。因此,作为一种节能、环保道路维修方法和新工艺,路面冷再生机已经成为道路改造的重要设备之一。
The construction of cold regeneration process is characterized by simple process, few construction facilities and low traffic interference, because the whole set of equipment can be in the same lane, which does not affect the traffic of vehicles in another lane. It can carry out open construction, especially suitable for road construction with large traffic volume or narrow road width. When half of the road is constructed, the other half is opened as usual, which greatly improves the traffic situation. Therefore, as an energy-saving and environmental protection road maintenance method and new technology, the pavement cold recycling machine has become one of the important equipment for road reconstruction.
