The present invention relates to an aromatic enriched deasphalted oil extract fraction for preparing bitumen. The present invention also relates to a process for preparing the aromatic enriched deasphalted oil extract fraction for preparing bitumen. The present invention further relates to bitumen and process for preparing the bitumen using the aromatic enriched deasphalted oil extract fraction. The aromatic enriched deasphalted oil extract fraction obtained in accordance with the present invention can be used preparing plurality of grades of bitumen. Also, bitumen obtained in accordance with the present invention contains extremely low concentration of poly cyclic aromatics and more particularly benzo(a)pyrene.
