At the elevated temperatures used in these industries, asphalt emits fumes. Concerns about the possible presence of carcinogenic PACs in asphalt fumes prompted the National Institute of Occupational Safety and Health (NIOSH) to sponsor two mouse skin-painting bioassays[1,2] of roofing asphalt fumes ...
A study on a demonstration project in Iron Mountain, Michigan determined that the advantages of WMA included lengthening truck haul distances, emission reduction, an extended paving window due to a longer cooling time, and fewer associated health concerns for road crews [22,97]. It was found ...
Moreover, some researches proved that the asphalt fumes generated in the laboratory did not match properly with those deriving from the construction site (Kriech et al., 2007, Reinke et al., 2000) in terms of both chemical composition and biological response (Clark et al., 2011). Therefore...

The other benefits of the paving temperature being closer to the ambient temperature and heat are less dramatic: longer hauling distance, sooner opening of a traffic lane, less exposure to fumes, and a healthy work environment, which reduces the risk of health problems among the workers. Author...
Odour emissions are therefore one of the main concerns for the hot-mix asphalt industry, the EAPA (European Asphalt Pavement Association) in Europe and the NAPA (National Asphalt Pavement Association) in the United States, which have started technical discussions to address this strategic issue [11...
This paper examined the use of asphalt pavement for construction purposes, focusing on its impact on energy consumption and carbon dioxide emissions. Over recent decades, there has been a considerable increase in the demand for road infrastructure, accompanied by growing concerns about its detrimental ...
With the use of WMA, it is therefore possible to reduce emissions, harmful fumes resulting in a lower risk to workers’ health. However, reduced manufacturing temperatures can affect the drying process of the aggregates before mixing, and proper aggregates–bitumen adhesion/coating, and ...
