在人們開始關(guān)注不同行業(yè)的相關(guān)信息時,每個行業(yè)的特殊點開始得到人們的關(guān)注,比如道路施工方面,冷再生機是一種非常好的舊瀝青路面改造機器。
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: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。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,實際上就是一臺大型的穩(wěn)定土路拌機) , 在自然常溫下, 就地連續(xù)完成對舊鋪層( 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, 修建出一種特殊級配的道路基層(或底基層) 。
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、就地冷再生機出租后適用范圍廣,施工優(yōu)勢明顯,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),致使新道路的面層至少要在此標(biāo)高的基礎(chǔ)上開始鋪筑, 況且在高標(biāo)準(zhǔn)的道路改造中, 有時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)大于原來路面的標(biāo)高,沿路構(gòu)造物處路面的設(shè)計結(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. 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.
