Relationship between chemical composition and VOCs emission potential of similar paving grade road bitumen
Publication
The objective of this study was to outline a possible relationship between chemical composition of bitumen and compounds emission during heating using thirteen 35/50 paving grade bitumen samples used in France. The samples are similar regarding their physical properties, elemental and SARA compositions. GC-FID, GCxGC/TOF-MS and GPC-UV investigation show that they contain the same class of compounds but in different proportions. Thermal analyses revealed different capacities of volatiles release potential. Combination of these data allowed to establish a relationship between chemical composition and volatile emission, leading to the identification of two groups of samples. Thus we suggest three parameters that may distinguish bitumen by their emission potential prior to road pavement application. They may contribute to a methodology aiming to prevent workers exposure to bitumen fumes during road paving operations.
