冷再生机施工对旧沥青路面的改造是有用的

来源:http://www.tclqgc.com/ 日期:2022-09-17 发布人:guanli
在旧沥青路面改造方面,使用冷再生机完全可以达到相应要求,而且可以获得很好的经济和社会效益。实践证明,冷再生机租赁施工对旧沥青路面的改造是科学可行的。
In the reconstruction of old asphalt pavement, the use of cold recycling machine can completely meet the corresponding requirements, and can obtain good economic and social benefits. The practice proves that the reconstruction of the old asphalt pavement by renting the cold recycling machine is scientific and feasible.
沥青路面就地冷再生并不是将已破损的沥青路面重新恢复到完好的原始状态,而是将旧面层和部分基层一并打碎混合之后就地改建成新的基层(或底基层)。因此,该工艺也可以被称为旧沥青路面材料的就地再利用。
In situ cold recycling of asphalt pavement is not to restore the damaged asphalt pavement to its original state, but to smash and mix the old surface course and part of the base course together and then rebuild them into a new base course (or subbase course). Therefore, this process can also be called the in-situ reuse of old asphalt pavement materials.
也就是在原有旧路铺层的基础上,按照新的设计要求,选择性地掺入适量的骨料、水泥、石灰、粉煤灰、乳化沥青、泡沫沥青和水等外加材料。
That is to say, on the basis of the original pavement of the old road, according to the new design requirements, an appropriate amount of additional materials such as aggregate, cement, lime, fly ash, emulsified asphalt, foam asphalt and water are selectively mixed.
利用冷再生机租赁设备,在常温下就地连续完成对旧铺层(路面和部分基层)的铣刨、破碎、添加料、拌和、摊铺等工序,随后进行找平和碾压,得到符合要求的道路基层(或底基层)。
Use the leased equipment of the cold recycling machine to continuously complete the milling, crushing, adding materials, mixing, paving and other processes of the old pavement (pavement and part of the base course) at room temperature, and then carry out leveling and rolling to obtain the required road base (or subbase).

由于就地冷再生施工是将原道路的面层和基层变成了新的道路基层(或底基层),致使新道路的面层至少要在此标高的基础上开始铺筑。
As the construction of on-site cold recycling is to change the surface course and base course of the original road into a new road base (or subbase), the surface course of the new road must be paved at least on the basis of this elevation.
而在高标准的道路改造中,有时是将再生层作为底基层,在此基础上还要加铺二灰碎石等基层材料,这就使得改造之后的路面标高远远高于原来路面的标高。
In the reconstruction of high standard roads, sometimes the recycled layer is used as the subbase, and lime fly ash macadam and other base materials are also paved on this basis, which makes the elevation of the reconstructed road surface much higher than that of the original road surface.
如果在城市道路中采用此法施工,原有的排水系统也会受到一些影响。因此,对于路面标高有较严格限制的道路,不宜采用此法施工。
If this method is used in urban road construction, the original drainage system will also be affected. Therefore, this method should not be used for roads with strict limitation on pavement elevation.
虽然冷再生机租赁的适用范围受到路面标高的限制,但在大多数的道路改造中,它依然具有其它传统改造方式所无法企及的优势。更多相关事项就来我们网站http://www.tclqgc.com咨询了解吧。
Although the scope of application of the cold recycling machine lease is limited by the road surface elevation, it still has advantages that other traditional reconstruction methods cannot achieve in most road reconstruction.
