| Abstract | ||
| Hot mix asphalt (HMA) is a major construction material used for building roads, airport runways, and parking lots (ASCE 2014). During HMA construction, a massive amount of volatile organic compounds (VOC'Ss) is emitted from the hot asphalt mixtures, creating a potential health risk to on-site workers. Few studies have quantitatively investigated (Chong et al., 2013). The constituents and the potential health effects of the VOC's generated from HMA pavement construction were studied. This paper presents the results of a study in which air samples were collected at multiple locations and time points of several projects during HMA pavement construction and were their chemical compositions and concentrations subsequently characterized by using gas chromatography/mass selective detector (GC/MSD). Although the individual concentrations of the identified chemicals were found to be below various exposure limits, their collective effect on human health remains unknown and may not be ignored (Chong et al., 2013). | ||
