概述冷再生机的沥青路面施工原理和优点!

来源:https://www.sddhfjx.com/ 日期:2021-04-27
在人们开始关注不同行业的相关信息时,每个行业的特殊点开始得到人们的关注,比如道路施工方面,冷再生机是一种非常好的旧沥青路面改造机器。
When people begin to pay attention to the relevant information of different industries, the special points of each industry begin to get people's attention, such as road construction, cold recycling machine is a very good old asphalt pavement reconstruction machine.
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。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, 修建出一种特殊级配的道路基层(或底基层) 。
1. Construction principle of in situ cold recycling: the in situ cold recycling of asphalt pavement is not to restore the damaged asphalt pavement to its original state as commonly understood, but to crush and mix the old surface course and part of the base course together and then rebuild it into a new base course (or sub base course) on the spot. Strictly speaking, this process should be called on-site reuse of old asphalt pavement materials. The principle of cold in place recycling is to select the right amount of aggregate, cement, lime, fly ash, emulsified asphalt, foam asphalt and water, and use the local cold recycling equipment on the basis of the old pavement. Milling, crushing, adding materials, mixing, paving and other processes of the old paving layer (pavement and part of the base) are continuously completed on site, and then leveling and rolling are carried out to build a special grading road base (or subbase).

2、就地冷再生机出租后适用范围广,施工优势明显,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, 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. After renting, the local cold recycling machine has a wide range of application and obvious construction advantages. Because the local cold recycling construction is to change the original road surface and base into a new road base (or subbase), the new road surface should be paved at least on the basis of this elevation. Moreover, in the high standard road reconstruction, sometimes the recycled layer is used as the subbase, On this basis, it is necessary to pave lime fly ash macadam and other base materials, which makes the elevation of the reconstructed pavement much higher than that of the original pavement, and the design structure of the pavement along the road structure will change accordingly. If this method is used in urban road construction, the original drainage system will also be affected. Therefore, it is not suitable to use this method for roads with strict restrictions on pavement elevation.
