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

在現(xiàn)在道路建設(shè)的基礎(chǔ)上， 我們有很多公路方面的技術(shù)問(wèn)題需要解決。現(xiàn)在面臨公路運(yùn)輸已呈現(xiàn)出大流量、重荷載的局面。提高公路的使用價(jià)值是非常迫切的問(wèn)題。那么舊瀝青路面冷再生機(jī)租賃機(jī)械如何進(jìn)行施工呢？冷再生機(jī)租賃廠家為您講解。

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瀝青路面就地冷再生并不是人們通常所理解的將已破損的瀝青路面重新恢復(fù)到完好的原始狀態(tài)， 而是將舊面層和部分基層一并打碎混合之后就地改建成新的基層（ 或底基層） 。 嚴(yán)格地講， 此工藝應(yīng)該稱之為舊瀝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， 是在原有舊路鋪層的基礎(chǔ)上， 按照新的設(shè)計(jì)要求， 選擇性地?fù)饺脒m量的骨料、水泥、石灰、粉煤灰、乳化瀝青、泡沫瀝青和水等外加材料， 利用就地冷再生設(shè)備，實(shí)際上就是一臺(tái)大型的穩(wěn)定土路拌機(jī)） ， 在自然常溫下， 就地連續(xù)完成對(duì)舊鋪層（ 路面和部分基層） 的銑刨、破碎、添加料、拌和、攤鋪等工序， 隨后進(jìn)行找平和碾壓， 終修建出一種特殊級(jí)配的道路基層（ 或底基層） 。

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、就地冷再生的適用范圍和優(yōu)點(diǎn)由于就地冷再生施工是將原道路的面層和基層變成了新的道路基層（ 或底基層） ， 致使新道路的面層少要在此標(biāo)高的基礎(chǔ)上開(kāi)始鋪筑， 況且在高標(biāo)準(zhǔn)的道路改造中， 有時(shí)是將再生層作為底基層， 在此基礎(chǔ)上還要加鋪二灰碎石等基層材料， 這就使得改造之后的路面標(biāo)高遠(yuǎn)遠(yuǎn)大于原來(lái)路面的標(biāo)高，沿路構(gòu)造物處路面的設(shè)計(jì)結(jié)構(gòu)將隨之發(fā)生變化。如果在城市道路中采用此法施工，原有的排水系統(tǒng)也將隨之受到一些影響。 因此， 對(duì)于路面標(biāo)高有較嚴(yán)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.

雖然就地冷再生的適用范圍受到路面標(biāo)高的限制，但在多數(shù)的一般道路改造中，與傳統(tǒng)的施工方法相比，依然具有諸多的優(yōu)點(diǎn)。來(lái)我們網(wǎng)站http://www.393444a.com，咨詢?cè)敿?xì)內(nèi)容！
