Laboratory Characterization of Hot Mix Asphalt Fumes During Mixing Linked with Mechanical Performances
A feasibility study has been carried out in order to estimate in laboratory the fumes emission potential during hot mix asphalt production in relation to manufacturing parameters. Temperature, binder content as well as some proceeding kinetics parameters have been studied through an experiment plan. The laboratory mixer was equipped with a stack for gas emission sampling in normalized conditions. A polycyclic aromatic hydrocarbons (PAH) sampling system has been designed and a continuous total organic compounds (TOC) analyzer has been used for hot mix asphalt fumes. Classical laboratory characterizations have been performed in order to estimate material performances. Among the possible ones, complex modulus of recovered binder or mix seems the most relevant as its result reflects mechanical properties as well as binder oxidation and ageing. The study performed allows to link potential fume emissions to mixing parameters for hot mix asphalts, in relation with mix mechanical properties.
