| Abstract | ||
| In this study, we modify the rheolgical prioperties of asphaltic materials by addative and air blowing. For this process, asphaltic materials have been oxidized by air blowing in the presence of anhydrous aluminum chloride as a catalyst for this process . Air blowing was conducted in different condtions of temperature and times using 0.5%(by weight) from catalyst, after determining the optimal conditions for air blowing, we changged the percentage of catalyst to get the optimal perecentage which can be using in modified process, then the asphalt was treated with the commercial adhesive (EVA) in two phaths: The first path was included addtion of different percentages from commercial adhesive under the optimal condition from air blowing and perecentage of alaminum chloride. The second path was included dissolved the commercial adhesive in the toluene and then the modified process was conducted at same conditions in the first path, ( toluene was added to the commercial adhesive by ratio (1:6) (weight of commercial adhesive: ml of toluene). The results showe rheological properties that are compeletly differentj from the original asphaltic materials . The study was gave modified asphaltic materials that can be using in different fields, some samples can be using in paving as in samples (AS19, AS24, AS25) and other as mastic or as flattening as in samples (AS15, AS16, AS17, AS21, AS22). The usage of asphalitic materials in various fields depends on the measurments of different properties such as (ductility, penetration, softining point ,asphaltens percentage, penetration index ,aging test, marshall test). | ||
