就地冷再生是指充分利用現(xiàn)有瀝青道路舊鋪層材料（面層與基層），根據(jù)對(duì)混合料性能的要求，加入部分新骨料，并按設(shè)計(jì)加入一定量的水泥，在自然環(huán)境溫度下連續(xù)地完成材料的銑刨、破碎、拌合、攤鋪及壓實(shí)成型，從而修筑出具有所需性能質(zhì)量的新基層的作業(yè)過(guò)程。

Local cold recycling refers to the operation process of making full use of the existing asphalt pavement materials (surface course and base course), adding some new aggregates according to the requirements of the mixture performance, and adding a certain amount of cement according to the design, and continuously completing the milling, crushing, mixing, paving and compaction of the materials under the natural ambient temperature, so as to build a new base course with the required performance quality.

以道路的養(yǎng)護(hù)維修中應(yīng)用的冷再生基層為例，闡述全深式水泥就地冷再生施工工藝，利用現(xiàn)有瀝青道路舊鋪層材料（面層與基層），根據(jù)對(duì)混合料性能的要求，并按設(shè)計(jì)要求加入不小于5%的水泥，在自然環(huán)境溫度下連續(xù)地完成材料的銑刨、破碎、拌和、攤鋪及壓實(shí)成型，從而修筑出具有所需性能質(zhì)量的新基層的作業(yè)過(guò)程。

Taking the cold-recycled base course applied in road maintenance as an example, this paper expounds the construction process of full-depth cement cold-recycled in situ, using the existing asphalt pavement materials (surface course and base course), according to the requirements of the mixture performance, and adding no less than 5% cement according to the design requirements, and continuously complete the milling, crushing, mixing, paving and compaction of the materials under the natural ambient temperature, So as to build a new base with the required performance quality.

冷再生機(jī)出租廠家認(rèn)為其實(shí)是相對(duì)全深式就地冷再生而言，全深式就地冷再生的施工深度為30-50公分左右，淺層就地冷再生只針對(duì)10公分左右的瀝青層就行就地冷再生，這是兩種就地冷再生直接的區(qū)別。

The rental manufacturer of the cold regenerator believes that the construction depth of the full deep local cold regeneration is about 30-50 cm, and the shallow local cold regeneration only applies to the asphalt layer of about 10 cm, which is the direct difference between the two kinds of local cold regeneration.

一，非常良好的利用舊路面材料。

1、 Very good use of old pavement materials.

二，施工速度快，施工周期短。

2、 The construction speed is fast and the construction period is short.

三，總投資小，解決施工成本。

3、 The total investment is small, which can solve the construction cost.

四，因?yàn)闉r青溫度低，實(shí)現(xiàn)

4、 Because of the low temperature of asphalt, energy conservation and environmental protection are realized

需要一臺(tái)再生設(shè)備、乳化瀝青罐車、拾料機(jī)、攤鋪機(jī)和壓路機(jī)等。施工前在原路面通過(guò)粉料撒布車撒布水泥。再生銑刨設(shè)備將路面進(jìn)行銑刨，同時(shí)向銑刨室加入瀝青，銑刨室內(nèi)進(jìn)行攪拌后輸送到后方，通過(guò)拾料機(jī)和攤鋪機(jī)進(jìn)行攤鋪，后進(jìn)行壓實(shí)作業(yè)。更多相關(guān)內(nèi)容點(diǎn)就來(lái)我們網(wǎng)站http://www.393444a.com咨詢！

A regeneration equipment, emulsified asphalt tanker, material picker, paver and roller are required. Before construction, cement shall be distributed on the original road surface by powder spreader. Regenerative milling equipment milles the road surface and adds asphalt to the milling room. The asphalt is mixed in the milling room and then transported to the rear. The asphalt is paved by the material picker and paver and then compacted. Come to our website for more relevant content http://www.393444a.com consulting service
