The modification of asphaltic materials with polymeric materials and other additives is one of the most important processes or modifications that take place on asphalt materials. The purpose of these modified that take place is the main purpose of which is to obtain asphaltic materials with a good specifications for the purposes for which it is used, whether that use is in the field of paving, flattening or as a mastic. This study included the treatment of asphaltic materials with modified materials represented by polyvinyl chloride and spent lubricating oils. The asphalt was treated with these additives in different percentages and in the presence of sulfur again and again in the presence of sulfur with anhydrous ferric chloride as acatalyst at a temperature of 150 ° C. An air blowing process was used on both paths. The rheological properties of the original asphalt and the modified and original samples were measured (penetration, softining point and ductility In addition, penetration index was calculated) for all samples After that, the samples were left for the aging factors for a period of 12 months. The rheological properties were measured again. This study gave a good samples when compared to standard samples.
