The use of recycled materials is regulated by standards for chemical analysis of leachate and binders. This study, based on air emission contribution aims at completing the comprehensive framework for RAP acceptance in road construction. Results show that fumes studied are composed of PAH in low quantities and in variable proportions depending on the manufacturing process and the mix design. Incorporation of 40 % recycled material into hot and warm manufacturing process increases total PAH concentrations in emissions by 8 % and 26 %, respectively. In addition, the results showed that carcinogenic particulate PAH in emissions from mixes incorporating recycled materials are attributable to RAP itself, suggesting that the pavement capture organic compounds functioning as a pollution sink. Importance of integrating a specific analysis of air emissions into the overall environmental characterization with the analysis of some pollutants will opened to directing road infrastructure construction and maintenance strategies towards more sustainable industrial practices.
