[en] Car manufacturers are faced with increasingly severe European regulations concerning End of Live Vehicles (ELV) recycling. Issues for the coarse fractions of Automotive Shredder Residue (ASR) are now quite largely studied. However, the European objectives could only be achieved by considering the processing and valorization of the fine ASR fraction (< 2mm) which usually represents 5 to 10 wt.% of shredded ELV. A laboratory study was carried out on the fine ASR fraction. By combining granulometric, gravimetric and magnetic separations, four valorizable fractions were identified. This paper presents the valorization of the finest fraction (< 250 μm) as filler in bituminous concrete. Physical and chemical properties were first determined. Bituminous concrete samples were then prepared with different substitution levels of calcareous filler by fine ASR. Marshall tests (mechanical properties) and leaching tests were performed without compromising results.
