Abstract AR
لغرض الحصول على مفهوم أفضل لأداء الأسفلت المستعمل في أعمال التبليط فقد أجري التحليل الكيميائي التجزيئي لخمسة نماذج مأخوذة من مصافي العراق الخمسة (القيارة، الناصرية، بيجي، السماوة و الدورة) التي تضمنت مكونات : (asphaltenes, polar compounds, first acidaffins, second acidaffins and saturated hydrocarbons) و تدعى المقاطع الأربعة الأخيرة maltenes تم استخراج كل من (PC / S) polar compounds/saturated hydrocarbons و نسبة التحمل التي تمثل نسبة المقاطع التجزيئية الفعالة إلى المقاطع التجزيئية غير الفعالة للـ maltenes لكل أنموذج أسفلت.
لقد بينت الدراسة أن الأسفلت المنتج في مصفى بيجي كان أفضل أنواع الأسفلت تحملا من غيره من أنواع الأسفلت الأخرى المنتج في باقي المصافي العراقية فيما عدا أسفلت القيارة أقلهم درجة تحمل.
Abstract EN
In order to get better understanding of asphalt pavement performance, asphalt from five Iraqi refineries (Qayarah, Nassiriyah, Baiji, Samawah and Daurah) were analyzed into five chemical fractions including asphaltenes, polar compounds, first acidaffins, second acidaffins and saturated hydrocarbons where the last four fractions called maltenes.
Polar compounds / saturated hydrocarbons ratio (PC/S) and the ratio of the reactive to the un-reactive components of the maltenes fraction (durability rating) parameters were determined.
The study showed that Baiji asphalt has the best durability over other asphalts, while Qayarah asphalt is considered to have the least durability grade.
These results confirm the correlation of the chemical composition of asphalt as a function of its durability.
