【摘要】:本文通過詳細分析瀝青面層所用原材料的獲取和施工過程中的節(jié)能降排影響因素,提出了瀝青面層的節(jié)能降排評估指標體系,并采用專家打分的方法確定瀝青面層節(jié)能降排評估指標系統(tǒng)中各個指標的比重,舉例給出了路面面層的節(jié)能降排評估流程和節(jié)能降排措施。 首先,本文分析了瀝青面層原材料在獲取階段和施工階段節(jié)能降排影響因素,并測試了不同混合料的施工溫度對能耗與排放的影響。 其次,通過闡述瀝青面層節(jié)能降排指標系統(tǒng)的建立依據(jù),確定了瀝青面層節(jié)能降排指標體系和框架的建立的基本要求,建立了瀝青面層節(jié)能降排評估指標系統(tǒng)。根據(jù)研究,評估標準體系由定性分析指標和定量分析指標兩部分組成,分別包括一級指標與二級指標。一級指標有四個,二級指標有24個。并且,通過專家打分的辦法,確定了瀝青面層節(jié)能降排評估系統(tǒng)中各個指標權重。最后,本文提出了瀝青面層節(jié)能降排模糊綜合評估辦法,,建立瀝青面層的節(jié)能降排模糊綜合評估程序。 從評估指標權重結(jié)果可以看出,能源消耗指標的權重較大,且其下級指標中混合料拌合階段和原材料生產(chǎn)階段的權重之和約為0.9。根據(jù)分析結(jié)果看,瀝青面層的節(jié)能降排措施主要從四個大的方面著手:一是原材料的節(jié)能降排(原材料生產(chǎn)、應用再生混合料)、二是瀝青及混合物拌合階段的節(jié)能降排(改進拌合樓、鼓勵使用瀝青混合料的溫拌工藝)、三是施工過程中的機器設備的保養(yǎng)使用、四是工程施工工藝控制。
[Abstract]:Based on the detailed analysis of the acquisition of raw materials used in asphalt surface and the influencing factors of energy saving and emission reduction during construction, the evaluation index system of energy saving and discharge reduction of asphalt surface is put forward in this paper. The expert scoring method is used to determine the proportion of each index in the evaluation index system of asphalt surface energy saving and emission reduction, and an example is given to give the evaluation flow and measures of energy saving and emission reduction of pavement surface. Firstly, this paper analyzes the influence factors of energy saving and emission reduction in the acquisition stage and construction stage of asphalt surface material, and tests the influence of construction temperature of different mixture on energy consumption and emission. Secondly, by expounding the foundation of asphalt surface energy saving and emission reduction index system, the basic requirements of asphalt surface energy saving and emission reduction index system and framework are determined, and the evaluation index system of asphalt surface energy saving and emission reduction index system is established. According to the research, the evaluation standard system consists of qualitative analysis index and quantitative analysis index, including the first grade index and the second grade index respectively. There are four primary indicators and 24 secondary indicators. In addition, the weight of each index in the evaluation system of energy saving and emission reduction of asphalt surface layer is determined by the method of expert scoring. Finally, the fuzzy comprehensive evaluation method for energy saving and emission reduction of asphalt surface is put forward, and the fuzzy comprehensive evaluation program for energy saving and emission reduction of asphalt surface is established. It can be seen from the result of evaluation index weight that the weight of energy consumption index is large, and the sum of the weight of mixture mixing stage and raw material production stage is about 0.9. According to the results of the analysis, the measures of saving energy and reducing emission of asphalt surface layer mainly start from four aspects: first, the energy saving and reducing discharge of raw materials (raw material production, In the application of recycled mixture, the second is to save energy in the mixing stage of asphalt and its mixture (to improve the mixing building, to encourage the use of warm mixing process of asphalt mixture, to maintain and use the machinery and equipment in the construction process, and to control the engineering construction process).
