为研究温拌沥青混合料的施工质量与烟气减排效果，依托实际养护工程，采用APTL温拌技术铺筑沥青路面，通过现场压实度、渗水系数等参数测定评价施工质量；在拌和站进行烟气排放定量分析，评价烟气减排效果。结果表明：采用APTL温拌技术并降低30℃施工，完工路面压实度等质量控制参数完全符合热拌沥青混合料施工技术要求，可有效保证施工质量；拌和过程中沥青烟实测浓度和排放速率分别下降了81．9％和82．3％；烟气中CO含量减少90％，SO2、NOx及苯并芘等降幅均在60％以上，有效地改善沥青混合料生产对环境的污染和人体的伤害。

In order to research the construction quality and emission reduction,warm mix asphalt added APTL warm mix additive is designed and paved in maintenance project,the construction quality is evaluated with compactness and permeability coefficient in the construction site,and quantitative analysis is made in the mixing plant to evaluate the emission reduction of asphalt fume.The results show that WMA can be mixed and compacted as good as HMA at a 30℃lower temperature by means of comparation on compactness or other quality parameters,effectively ensuring the construction quality;compared with HMA,concentration and emission rate of asphalt fume in mixing process reduced 81.9 % and 82.3 %;the content of CO reduced by 90 %,SO2,NOx and benzopyrene reduced by more than 60 %,and it greatly improved the environment of asphalt mixing,reduced atmosphere pollution and harm to health.
