Modification of The Rheological Properties of Asphalt Using Spent Lubricating Oils and Air Oxidation

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.<br /> 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)
