廠拌冷再生結(jié)構(gòu)主要用于瀝青路面的基層,屬于“半柔性基層”范疇,它可預(yù)防反射裂縫,從而延長(zhǎng)瀝青面層的使用壽命;銑刨后舊料回收利用,可以避免污染環(huán)境,符合提倡的建設(shè)節(jié)約型、可持續(xù)發(fā)展的時(shí)代主流。冷再生基層施工工藝經(jīng)過(guò)多個(gè)實(shí)際工程應(yīng)用,取得了良好的經(jīng)濟(jì)效益和社會(huì)效益,冷再生能更加有效的控制材料的質(zhì)量與路用性能。
The plant mix cold recycling structure is mainly used in the base of asphalt pavement, which belongs to the category of "semi flexible base". It can prevent reflection cracks and prolong the service life of asphalt pavement; After milling, the old material can be recycled to avoid environmental pollution, which is in line with the mainstream of the era of building a conservation oriented and sustainable development. After several practical engineering applications, the construction technology of cold recycling base course has achieved good economic and social benefits. Cold recycling can more effectively control the quality of materials and road performance.
冷再生技術(shù)有較好的儲(chǔ)存功能,通過(guò)冷再生處理的混合料可以在一定時(shí)間內(nèi)儲(chǔ)存?zhèn)溆茫朔司偷乩湓偕械纳a(chǎn)和攤鋪相互依賴的缺陷。泡沫瀝青再生混合料中以舊路材料為主,有效的解決了銑刨料的再生利用,同時(shí)可以避免污染環(huán)境。冷再生處理有效地解決了發(fā)泡效果以及銑刨料的破碎程度,保證了冷再生混合料的路用性能。
Cold recycling technology has a good storage function. The mixture treated by cold recycling can be stored for standby in a certain period of time, which overcomes the defect of interdependence between production and paving in the on-site cold recycling. Foamed asphalt recycling mixture is mainly made of old road materials, which effectively solves the regeneration and utilization of milling materials, and avoids polluting the environment. Cold recycling treatment can effectively solve the foaming effect and the crushing degree of milling material, and ensure the road performance of cold recycling mixture.
路面標(biāo)高可以不抬高或抬高較少,減少了擋墻、邊溝、綠化帶等附屬設(shè)施的加高費(fèi)用;在面層結(jié)構(gòu)設(shè)計(jì)中可以減薄瀝青面層厚度,從而有效地節(jié)約投資。冷再生技術(shù)是指將舊瀝青混凝土面層挖除或銑刨,再運(yùn)送至料場(chǎng)堆放存貯。我們根據(jù)材料的情況破碎或過(guò)篩后,通過(guò)固定的施工設(shè)備,根據(jù)需要添加新料進(jìn)行攪拌并噴入泡沫瀝青,生產(chǎn)泡沫瀝青再生混合料,然后運(yùn)送至道路施工現(xiàn)場(chǎng)。
The elevation of the road surface can not be raised or raised less, which reduces the cost of heightening the retaining wall, side ditch, green belt and other ancillary facilities; In the design of surface structure, the thickness of asphalt surface can be reduced, so as to save investment effectively. Cold recycling technology refers to the excavation or milling of old asphalt concrete surface, and then transported to the stockyard for storage. According to the condition of the material, we break or sift through the fixed construction equipment, add new materials according to needs, stir and spray into foam asphalt, produce foamed asphalt regenerated mixture, and then transport it to the road construction site.
廠拌冷再生設(shè)備攤鋪壓實(shí)成型,成為一個(gè)路面結(jié)構(gòu)層次的施工工藝。由于瀝青泡沫的衰減速度很快,在生產(chǎn)泡沫瀝青再生混合料時(shí),需要在很短的時(shí)間內(nèi)與冷集料拌和,因此,泡沫瀝青再生混合料的拌和設(shè)各應(yīng)集材料傳送、瀝青發(fā)泡、混合料拌和等施工操作為一體。當(dāng)前泡沫瀝青混合料常作為冷再生基層應(yīng)用,屬于瀝青處置柔性基層的范疇。冷再生設(shè)備基層強(qiáng)度尚可,面層出現(xiàn)大面積病害的路段。
Plant mixing cold recycling equipment paves, compacts and forms, which becomes a construction technology of pavement structure level. Because the decay rate of asphalt foam is very fast, in the production of foamed asphalt recycling mixture, it is necessary to mix with cold aggregate in a very short time. Therefore, the mixing operation of foamed asphalt regeneration mixture should be one of the construction operations such as material transfer, asphalt foaming and mixture mixing. At present, foamed asphalt mixture is often used as cold recycling base, and belongs to the category of asphalt treated flexible base. The strength of cold recycling equipment base is acceptable, and the road section with large area disease on the surface layer.
