Abstract
Çalışmada, Kuzey Irak’ta bulunan LANAZ rafinerisinden ve Batman TÜPRAŞ rafinerisinden 2 farklı B 160/220 sınıfı saf bitüm temin edilmiştir. Bu bitümlere 3 farklı oranda (%2, %3 ve %4) stiren-etilen-bütadien-stiren (SEBS) ilave edilerek modifiye bitümler hazırlanmıştır. Saf ve modifiye bitümlere penetrasyon, yumuşama noktası, iki farklı sıcaklıkta (135 ve 165°C) dönel viskozite deneyleri uygulanmıştır. Ayrıca dinamik kayma reometresi (DSR) deneyleri ile tekerlek izi oluşumuna karşı dayanım parametreleri (G*/sin δ) belirlenmiştir. Farkı sıcaklık ve yükleme hızlarında DSR deneyi uygulanarak farklı koşullarda kompleks kayma modülü (G*) değerleri ile faz açıları belirlenmiştir. SEBS katkısı kullanılması ile bağlayıcıların penetrasyon ve faz açısı değerlerinin azaldığı, yumuşama noktası, viskozite, tekerlek izi parametresi, kompleks kayma modülü değerlerinin ise arttığı tespit edilmiştir. Yapılan analizler sonucunda yüksek sıcaklık dayanımı açısından Irak LANAZ rafinerisinden temin edilen bitümün Batman TÜPRAŞ rafinerisinden temin edilen saf bitüme göre daha olumlu sonuçlar verdiği belirlenmiştir. Modifiye bitümler değerlendirildiğinde Irak LANAZ bitümüne göre Batman TÜPRAŞ bitümü kullanılması durumunda daha etkili modifiye bitümler elde edildiği tespit edilmiştir.
