There is a growing need for the production of certain types of asphaltic materials having good rheological properties compared with the unmodified asphaltic materials, thus many experiments were performed to prepare a modified asphalt that can be used in different fields. This study aims to modify asphalt with the addition of (spent lubricating oils) with different percentages and with air blowing oxidation. From this work we obtained the asphaltic materials which can be used in paving and mastic production according to the measuring of the (ductility, penetration, asphaltene and softening point)
