摘 要

目前在资源与环境问题日益突出的国际背景下，国内外的广泛重视沥青路面在建设期间和运营养护期间产生的能耗高、温室气体及有害烟尘排放量大等环境问题。沥青路面运营期间是能耗和排放关键问题，特别是汽车行驶的能耗和排放占绝大部分。在沥青路面运营期间，路面养护施工中材料生产以及机械设备运行均会消耗大量的能量，并排放多种污染物质。

在文中对沥青路面运营期间的能耗和排放进行分析，例如对沥青原材料生产过程中的能耗和排放的分析等，同时也对汽车行驶的能耗和排放进行分析。所以建立沥青路面的运营期间的能耗和排放的量化分析是十分重要的。

Study on the carbon emission intensity of asphalt pavement maintenance

Abstract

Under the international background of resources and environmental problems are becoming  increasingly prominent,environmental prombles such as high energy consumption ,large emissions of greenhouse gases and harmful dust resulted from construtiom ,operation and maintenance of asphalt pavement have draw extensive attention both at home and aborad.The use phase of asphalt paverment is the key phase of energy usage and gas emissions in asphalt pavements life cycle ,especially the vehicles running on the roads,which take the lastest portion of the energy consumption and gas release.During the use phase of asphalt paverment,the material production and the operation of the material in pavement maintenance and construction will consume energy and emit pollutants.

During the operation ,I analyze the energy consumption and emissions of asphalt pavement ,such as on asphalt production process of raw materials used in energy consumption and emissions of analysis,I also analyze the energy consumption and emissions of vehicles, So it is very important to establish the energy consumption and emission during the operation of asphalt pavement..

Key word :asphalt pavement;maintenance；fuel consumption and emissions of vehicles ;energy consumption and gas emissions;pavement conditions;
