Reliable recycling machine leasing construction company, how to carry out comprehensive construction of old asphalt pavement cold recycling machine leasing machinery

在现在道路建设的基础上， 我们有很多公路方面的技术问题需要解决。现在面临公路运输已呈现出大流量、重荷载的局面。提高公路的使用价值是非常迫切的问题。那么旧沥青路面冷再生机租赁机械如何进行施工呢？冷再生机租赁厂家为您讲解。

On the basis of the current comprehensive road construction, we have a lot of technical problems related to roads to solve. Now China is facing a situation of large flow and heavy load in road transport. It is very urgent to improve the use value of highways. So how to carry out the comprehensive construction of the old asphalt pavement cold recycling machine rental machinery? The cold regeneration machine rental manufacturer will explain it to you.

1、就地冷再生的施工原理沥青路面就地冷再生并不是人们通常所理解的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） 。 严格地讲， 此工艺应该称之为旧沥青路面材料的就地再利用。

1. The construction principle of cold in place recycling of asphalt pavement is not to restore the damaged asphalt pavement to its original state, which is generally understood, but to rebuild the old surface course and some base course into a new base course (or subbase course) after they are crushed and mixed together. Strictly speaking, this process should be called the in-situ reuse of old asphalt pavement materials.

路面就地冷再生的工作原理， 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， 利用就地冷再生设备，实际上就是一台大型的稳定土路拌机） ， 在自然常温下， 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， 终修建出一种特殊级配的道路基层（ 或底基层） 。

The working principle of cold in place recycling of pavement is to selectively add appropriate aggregate, cement, lime, fly ash, emulsified asphalt, foam asphalt, water and other external materials on the basis of the original old pavement layer according to the new design requirements. Using the cold in place recycling equipment, it is actually a large stabilized soil road mixer, Milling, crushing, adding materials, mixing, paving and other processes of the old pavement (pavement and part of the base course) are continuously completed on the spot, followed by leveling and rolling, and finally a special graded road base (or subbase) is constructed.

2、就地冷再生的适用范围和优点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） ， 致使新道路的面层少要在此标高的基础上开始铺筑， 况且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大于原来路面的标高，沿路构造物处路面的设计结构将随之发生变化。如果在城市道路中采用此法施工，原有的排水系统也将随之受到一些影响。 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。

2. Scope of application and advantages of in situ cold recycling. Because the construction of in situ 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 should be paved at least on the basis of this elevation. In addition, in high standard road reconstruction, sometimes the recycled layer is used as the subbase, and on this basis, lime fly ash macadam and other base materials should be paved, This makes the reconstructed pavement elevation much higher than the original pavement elevation, and the design structure of the pavement along the road structures will change accordingly. 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.

虽然就地冷再生的适用范围受到路面标高的限制，但在多数的一般道路改造中，与传统的施工方法相比，依然具有诸多的优点。来我们网站，咨询详细内容！
