【摘要】：阜新經(jīng)過(guò)多年的艱難轉(zhuǎn)型后,經(jīng)濟(jì)迅速增長(zhǎng),生態(tài)環(huán)境得到改善。公路是經(jīng)濟(jì)發(fā)展的重要媒介,阜新政府每年都要投入大量的財(cái)力和物力用于公路的維修和養(yǎng)護(hù)。巨大卻必要的開支使公路在促進(jìn)阜新邁向復(fù)蘇的同時(shí),也減緩了經(jīng)濟(jì)增長(zhǎng)的速率。同時(shí),大量砂石樹木的開采也違背了阜新“構(gòu)建園林城市”的初衷。就地冷再生技術(shù)經(jīng)濟(jì)、環(huán)保,阜新地區(qū)雖有很多施工實(shí)例,但尚未形成完整的理論體系。因此,為了適應(yīng)阜新經(jīng)濟(jì)發(fā)展和環(huán)境保護(hù)的需求,本文重點(diǎn)對(duì)就地冷再生技術(shù)展開研究,使這項(xiàng)技術(shù)更好地服務(wù)于阜新的發(fā)展。本文以阜新市育紅路到迎賓大街主干路的基層就地冷再生項(xiàng)目為工程實(shí)例,按照設(shè)計(jì)、施工、評(píng)價(jià)的順序?qū)偷乩湓偕夹g(shù)進(jìn)行研究,共分為四個(gè)階段：方案設(shè)計(jì)階段,以試驗(yàn)路為例闡述了大修方案的選擇依據(jù)和方法,總結(jié)出設(shè)計(jì)流程和步驟；配合比設(shè)計(jì)階段,分析了舊路銑刨料的級(jí)配組成,測(cè)定了不同水泥摻量下試件的最大干密度和最佳含水率,以無(wú)側(cè)限抗壓強(qiáng)度為強(qiáng)度標(biāo)準(zhǔn),確定試驗(yàn)路的水泥摻量為5%或6%均可,粗骨料摻量為15%最佳；施工階段,通過(guò)試驗(yàn)路的鋪筑,詳細(xì)闡述了就地冷再生的施工工藝,形成了較完整的施工理論體系。評(píng)價(jià)階段,分析了就地冷再生技術(shù)的可行性、經(jīng)濟(jì)合理性和社會(huì)效益。評(píng)價(jià)其社會(huì)效益時(shí),提出社會(huì)效益可分為對(duì)于社會(huì)的經(jīng)濟(jì)效益和對(duì)于生態(tài)的環(huán)境效益兩方面,并重點(diǎn)對(duì)環(huán)境效益作出論證,提出并論證了可以將可持續(xù)發(fā)展理論作為評(píng)價(jià)就地冷再生技術(shù)環(huán)境效益的理論依據(jù),同時(shí)引入技術(shù)清潔性概念,指出技術(shù)清潔性是可持續(xù)發(fā)展理論技術(shù)層面的體現(xiàn),技術(shù)清潔性作為評(píng)價(jià)就地冷再生技術(shù)的環(huán)境效益切實(shí)可行,并給出評(píng)價(jià)技術(shù)清潔性的參考指標(biāo)。最后,基于可持續(xù)發(fā)展理論對(duì)就地冷再生技術(shù)的環(huán)境效益進(jìn)行了評(píng)價(jià),結(jié)果表明就地冷再生技術(shù)具有技術(shù)清潔性,體現(xiàn)了技術(shù)的可持續(xù)發(fā)展。通過(guò)工程的實(shí)施和對(duì)就地冷再生技術(shù)的技術(shù)經(jīng)濟(jì)評(píng)價(jià)可以得出：就地冷再生技術(shù)能夠適應(yīng)阜新發(fā)展的各項(xiàng)要求,節(jié)省經(jīng)濟(jì)開支,符合阜新發(fā)展綠色生態(tài)的理念,具有可持續(xù)性,應(yīng)在阜新地區(qū)大力推廣,必將為阜新帶來(lái)不可估量的經(jīng)濟(jì)和環(huán)境效益。
[Abstract]:After many years of difficult transformation, Fuxin has witnessed rapid economic growth and improved ecological environment. The highway is an important medium for economic development. Fuxin government has to invest a lot of financial and material resources in highway maintenance and maintenance every year. The huge but necessary expenditure makes the highway promote the recovery of Fuxin, but also slow down the rate of economic growth. At the same time. The exploitation of a large number of sand and stone trees is also contrary to the original intention of "building garden city" in Fuxin. Although there are many construction examples in Fuxin area, the local cold regeneration technology is economical and environmental protection, but it has not yet formed a complete theoretical system. In order to meet the needs of economic development and environmental protection in Fuxin, this paper focuses on the research of in-situ cold regeneration technology. This technology can better serve the development of Fuxin. This paper takes the local cold regeneration project from Yuhong Road to Yingbin Street in Fuxin City as an engineering example, according to the design, construction. Research on in-situ cold regeneration technology is carried out in the order of evaluation, which is divided into four stages: the design stage. Taking the experimental road as an example, the selection basis and method of the overhaul scheme are expounded, and the design process and steps are summarized. In the phase of mix ratio design, the gradation composition of the old road milling planer is analyzed, the maximum dry density and the optimum moisture content of the specimen under different cement content are measured, and the unconfined compressive strength is taken as the strength standard. The cement content of test road is 5% or 6%, and the content of coarse aggregate is 15%. In the construction stage, through the paving of the test road, the construction technology of local cold regeneration is expounded in detail, and a relatively complete construction theory system is formed. At the evaluation stage, the feasibility of the in-situ cold regeneration technology is analyzed. When evaluating the social benefits, the social benefits can be divided into two aspects: the economic benefits for the society and the environmental benefits for the ecology, and the emphasis is on the demonstration of the environmental benefits. The theory of sustainable development can be used as the theoretical basis for evaluating the environmental benefits of in-situ cold regeneration technology. At the same time, the concept of technology cleanliness is introduced. It is pointed out that the technical cleanliness is the embodiment of the theory and technology of sustainable development, and the technical cleanliness is feasible to evaluate the environmental benefit of the in-situ cold regeneration technology, and the reference index for evaluating the cleanliness of the technology is given. Based on the theory of sustainable development, the environmental benefits of in-situ cold recycling technology are evaluated. The results show that the in-situ cold recycling technology has the technical cleanliness. Through the implementation of the project and the technical and economic evaluation of the local cold regeneration technology, it can be concluded that the local cold regeneration technology can adapt to the requirements of the development of Fuxin and save economic expenses. In accordance with the concept of developing green ecology in Fuxin, it is sustainable and should be popularized in Fuxin area, which will bring inestimable economic and environmental benefits to Fuxin.
