【摘要】：能源消耗及其产生的排放引起的生态环境恶化越来越受到全社会的关注。在交通运输部积极推动绿色公路的环境下,厂拌乳化沥青冷再生、水泥再生土、高聚物注浆等具有节能减排效果的技术在安徽省高速公路改建工程中开始大规模应用。本文依托实际工程,采用全寿命周期分析方法,在现场数据调查的基础上,对改建工程各技术方案的能耗、排放进行量化分析,并提出沥青路面改建工程节能减排评价指标及模型。本课题研究内容如下:⑴沥青路面改建工程节能、减排分析与评价模型框架;⑵原材料生产期能源消耗与排放量化分析;⑶沥青路面改建工程施工期能耗与排放量化分析;⑷改建工程节能减排技术应用及效果分析;⑸沥青路面改建工程节能减排评价指标及评价体系。通过实地工程调研、数据分析得出以下主要结论:⑴依据生命周期分析方法,建立在沥青路面建设或改建工程中运用清单分析法的流程,结合绿色公路的要求及改建工程特点,明确了能耗、排放的量化计算方法,建立了适用于沥青路面改建工程节能减排量化与评价的基本模型框架。⑵1t再生集料生产能耗在0.51-0.66kgce之间,约为新集料能耗(0.86-1.29)的50%。依托改建工程项目共使用再生集料309814.1t,实现了废旧沥青面层材料的100%再生利用,由此节约新集料约300519.7t。⑶在沥青面层施工期的各个环节,沥青混合料拌和能耗与排放比重最大,分别为77.4%和82.1%,为施工过程中降低能耗与排放的关键环节。⑷1km冷再生基层结构层施工期的能耗和排放仅为大粒径沥青碎石基层的8.8%、7.8%。考虑原材料生产及施工期两个阶段,冷再生基层的能耗与排放是大粒径沥青碎石基层的60.9%、59.9%。1km冷再生基层比大粒径沥青碎石基层减少能耗、排放分别为7997.2kgce、22427.1kg。依托改建工程累计节约能耗1.88×106kgce、减少排放5.39×106kg,冷再生基层节能减排效果显著。⑸以“节材、节能、减排”为核心,确定沥青路面改建工程节能减排二级评价指标体系,提出基于绿色理念的节能减排综合量化评价方法。课题研究结果将有利于进一步推动节能减排技术措施的应用。
[Abstract]:The ecological environment energy consumption and emissions caused by the deterioration of more and more attention from the whole society. In the Department of transportation to actively promote green road environment, plant mixed cold recycling emulsified asphalt, cement soil regeneration, polymer grouting with energy saving and emission reduction technology began large-scale application in the reconstruction of Expressway in Anhui Province based on the project. The actual project, using life cycle analysis method, based on the survey data on the consumption of the reconstruction project of various technical schemes, quantitative analysis of emissions, and put forward the reconstruction of evaluation indexes and model of energy saving and emission reduction engineering of asphalt pavement. The content of this study are as follows: 1 the energy saving reconstruction project of asphalt pavement, the framework of model analysis and evaluation of emission reduction the production of raw materials; energy consumption and emission quantitative analysis; the analysis of energy consumption and emissions during the construction of the asphalt pavement reconstruction; Analysis of reconstruction project of energy saving and emission reduction technology application and effect; the reconstruction project of energy saving evaluation index and evaluation system of asphalt pavement engineering. Through field investigation, data analysis, the main conclusions are as follows: firstly according to the analysis method of life cycle, based on the asphalt pavement construction or renovation project in the use of inventory analysis process, combined with the characteristics of green highway requirements clear and rebuilding project, energy consumption, emission calculation method of quantification, the basic framework was established for asphalt pavement reconstruction project of energy saving and emission reduction in energy consumption. The quantitative analysis and evaluation of material production in the 0.51-0.66kgce between the regeneration 1t, about the new aggregate energy consumption (0.86-1.29) 50%. on reconstruction project using recycled aggregate 309814.1t. To achieve the 100% regeneration surface layer material by using waste asphalt, thus saving aggregate in each ring about 300519.7t. asphalt pavement construction period Section, material mixing energy consumption and emissions of asphalt mixture proportion, respectively 77.4% and 82.1%, which is the key link to reduce energy consumption and emissions in the process of construction. The 1km of cold recycling base layer structure during the construction of energy consumption and emissions of only large size asphalt macadam base 8.8% 7.8%., considering the raw material production and construction period of two a stage, energy consumption and emissions of cold recycling base is of large size asphalt macadam base 60.9%, 59.9%.1km cold recycling base than large size asphalt macadam base to reduce energy consumption and emissions are respectively 7997.2kgce, 22427.1kg. relying on energy saving reconstruction project total emission reduction of 1.88 * 106kgce, 5.39 * 106kg, cold recycling base energy saving effect is remarkable. According to "material saving, energy saving, emission reduction" as the core, to determine the reconstruction project of energy saving and emission reduction of two level evaluation index system of asphalt pavement, put forward the concept of green energy-saving emission reduction comprehensive quantitative evaluation method based on topic. The results of the study will be conducive to further promote the application of energy-saving emission reduction measures.
