The quantifying evaluations of asphalt volatile organic compounds (VOCs) throughout the road construction process are growing concerned since VOCs are widely recognized for its adverse effects on both human health and environmental issues. This paper made a comparison on VOCs emission assessment between actual construction field and laboratory simulation, aiming to verify their research gap at similar applied conditions. Atmospheric sampling pump and adsorption tube were used to record the VOCs samples from practical construction site, involving in hot asphalt storage tank, mixture plant, and paving site. Correspondingly, a sealed simulator for experimental VOCs collection was set-up in laboratory to investigate the VOCs amount released in different temperatures. Moreover, thermal desorption-gas chromatography-mass spectrometry (TD-GC-MS) was applied to analyse the detailed chemical composition and released quantification of VOCs samples. The results indicated that substance varieties and content in asphalt VOCs had considerable dependence on heating temperature. Both oxygen and thermality will trigger the increasing generation of hydrocarbon derivatives (HYD) in asphalt VOCs. For construction site, the investigated scenarios behaved great difference due to the complexity from on-site factors, however, approximating 74% of aliphatic hydrocarbons (ALH) tested in laboratory were fitted with the main components detected in construction site. Therefore, experimental simulation in laboratory could obtain a workable effect in signalling practical VOCs amount and compositions released in construction sites. This study provided a significant reference in connecting construction sites and laboratory research toward asphalt VOCs quantification. It laid down a basis for further total VOCs emission amount estimation and environmental effect assessment in the life-cycle of asphalt pavement construction, which is little concerned in corresponding research field.

由于人们对挥发性有机化合物对人体健康和环境问题均产生了不良影响，因此人们对挥发性有机化合物（VOC）的量化评估越来越关注。本文在实际施工现场和实验室模拟之间对VOCs排放评估进行了比较，旨在验证其在类似应用条件下的研究差距。大气采样泵和吸附管用于记录实际施工现场的VOCs样品，包括热沥青储存罐，混合料厂和铺路现场。相应地，在实验室中建立了用于实验性VOC收集的密封模拟器，以研究在不同温度下释放的VOC量。此外，采用热脱附-气相色谱-质谱法（TD-GC-MS）分析详细的化学成分并发布了挥发性有机化合物的定量分析方法。结果表明，沥青中挥发性有机化合物的物质种类和含量对加热温度有很大的依赖性。氧气和热量都会触发沥青VOC中碳氢化合物衍生物（HYD）的生成增加。对于建筑工地，由于现场因素的复杂性，所研究的情景表现出很大的差异，但是，在实验室测试的大约74％的脂肪烃（ALH）已与在建筑工地中检测到的主要成分相匹配。因此，在实验室进行的实验模拟可以有效地表明施工现场释放的挥发性有机化合物的数量和组成。这项研究为连接建筑工地和实验室研究沥青VOC量化提供了重要参考。为沥青路面施工生命周期中进一步的VOCs排放总量估算和环境影响评价奠定了基础，在相关研究领域对此鲜有关注。
