瀝青混凝土是道路建設(shè)過程中常見的基本施工材料，而且其具有足夠的強(qiáng)度和穩(wěn)定性。相比傳統(tǒng)的水泥混凝土路面，瀝青混凝土路面具有更平整，無接縫，行車平穩(wěn)，振動(dòng)小，噪聲低，施工期短，養(yǎng)護(hù)方便等優(yōu)點(diǎn)，因此瀝青混凝土路面成為了我國(guó)道路建設(shè)過程中的主要類型。而冷再生技術(shù)是道路建設(shè)的一種新型成熟技術(shù)，是利用冷再生機(jī)械設(shè)備加上相應(yīng)的材料、添加劑、水等將舊瀝青混凝土路面進(jìn)行銑刨、破碎、添加、拌合加工、攤鋪、壓實(shí)作業(yè)的過程。特別是對(duì)于大中修及路面改造工程，瀝青混凝土路面冷再生技術(shù)的出現(xiàn)大大降低了建設(shè)施工的成本，節(jié)省了材料并且提高了材料的利用率，既保護(hù)了環(huán)境，更帶來經(jīng)濟(jì)效益。瀝青混凝土路面冷再生技術(shù)擁有高適應(yīng)性，建設(shè)所需的工期短且建設(shè)成本低以及保護(hù)環(huán)境等優(yōu)點(diǎn)，在道路建設(shè)工作中受到了廣泛地使用，推動(dòng)了道路建設(shè)事業(yè)的發(fā)展。

Asphalt concrete is a common basic construction material in road construction, and it has sufficient strength and stability. Compared to traditional cement concrete pavement, asphalt concrete pavement has advantages such as smoother, seamless, smooth driving, less vibration, low noise, short construction period, and convenient maintenance. Therefore, asphalt concrete pavement has become the main type of road construction in China. Cold recycling technology is a new and mature technology in road construction, which uses cold recycling machinery and equipment with corresponding materials, additives, water, etc. to mill, crush, add, mix, process, pave, and compact the old asphalt concrete pavement. Especially for major and medium-sized repairs and road surface renovation projects, the emergence of cold recycling technology for asphalt concrete pavement has greatly reduced construction costs, saved materials, and improved material utilization, which not only protects the environment but also brings economic benefits. The cold recycling technology of asphalt concrete pavement has the advantages of high adaptability, short construction period, low construction cost, and environmental protection. It has been widely used in road construction work, promoting the development of road construction.

我國(guó)很多地方的道路路面損壞的情況都不容樂觀，有的是路面出現(xiàn)裂縫的現(xiàn)象，大大降低了路面的強(qiáng)度和承載，使路面遭到破壞，嚴(yán)重影響路面的正常通行。有的路面出現(xiàn)變形的情況，對(duì)行人以及車輛的安全通行都造成了一定的影響。冷再生技術(shù)主要應(yīng)用于舊路的路面、損壞的路面、逐漸老化的瀝青路面以及長(zhǎng)時(shí)期的使用導(dǎo)致過度疲勞而開裂的路面等。

The situation of road surface damage in many parts of our country is not optimistic, some of which have cracks on the road surface, greatly reducing the strength and bearing capacity of the road surface, causing damage to the road surface, and seriously affecting the normal traffic of the road surface. The deformation of some road surfaces has caused certain impacts on the safe passage of pedestrians and vehicles. Cold recycling technology is mainly applied to old road surfaces, damaged roads, gradually aging asphalt roads, and roads that crack due to excessive fatigue caused by long-term use.

它可以有效解決半剛性基層的反射裂縫問題，而且冷再生技術(shù)的施工工期比較短，在交通量很大的路面建設(shè)施工中也同樣試用，通過分期施工的方式修復(fù)路面不僅不會(huì)阻斷路面的交通而且所需的時(shí)間也大大降低。由于冷再生技術(shù)在修復(fù)路面時(shí)能夠二次利用原路面的材料，不需要再大量的購(gòu)買砂石等建筑材料從而提高了材料的利用率，減少了對(duì)資源的消耗達(dá)到了保護(hù)環(huán)境的效果。所以瀝青路面冷再生技術(shù)具有廣闊的工程前景。

It can effectively solve the problem of reflection cracks in semi-rigid base layers, and the construction period of cold regeneration technology is relatively short. It is also tested in the construction of road surfaces with high traffic volume. The repair of road surfaces through phased construction not only does not block traffic on the road surface, but also greatly reduces the time required. Due to the fact that cold recycling technology can reuse the materials of the original road surface during road repair, there is no need to purchase a large amount of building materials such as sand and gravel, thereby improving the utilization rate of materials and reducing resource consumption, achieving the effect of environmental protection. So the cold recycling technology of asphalt pavement has broad engineering prospects.

施工準(zhǔn)備工作是保證冷再生技術(shù)順利開展的前提，施工準(zhǔn)備期間需要對(duì)道路的信息情況進(jìn)行充分的采集與分析，從而制定出一個(gè)合理的施工方案。主要任務(wù)有以下幾點(diǎn)：一是對(duì)原路面的使用情況和原路面所處的環(huán)境進(jìn)行調(diào)查，并對(duì)相關(guān)的數(shù)據(jù)進(jìn)行統(tǒng)計(jì)。二是對(duì)原路面的嚴(yán)重?fù)p害路段進(jìn)行預(yù)處理，結(jié)合路面的實(shí)際情況對(duì)中下面層進(jìn)行徹底修復(fù)，確保基礎(chǔ)的承載力。三是合理調(diào)配人、材、機(jī)，在進(jìn)行冷再生技術(shù)前應(yīng)該對(duì)建設(shè)施工過程中所需用到的材料和設(shè)備等進(jìn)行檢查，保證其滿足施工的要求。四是進(jìn)行鋪設(shè)試驗(yàn)段，既能測(cè)量出各環(huán)節(jié)的施工所需要的溫度以及施工速度等相關(guān)數(shù)據(jù)，又能對(duì)各項(xiàng)指標(biāo)做出檢測(cè)，因此鋪設(shè)試驗(yàn)段很有代表性。

Construction preparation work is a prerequisite for ensuring the smooth implementation of cold recycling technology. During the construction preparation period, it is necessary to fully collect and analyze the information of the road, in order to develop a reasonable construction plan. The main tasks include investigating the usage of the original road surface and the environment in which it is located, and collecting relevant data. The second is to preprocess the severely damaged sections of the original road surface, and thoroughly repair the middle and lower layers based on the actual situation of the road surface to ensure the bearing capacity of the foundation. The third is to reasonably allocate personnel, materials, and machinery. Before implementing cold recycling technology, the materials and equipment required during the construction process should be inspected to ensure that they meet the construction requirements. The fourth is to conduct a laying test section, which can not only measure the temperature and construction speed required for each stage of construction, but also detect various indicators. Therefore, the laying test section is very representative.
