Bu çalışmada, atık çınar ağacı yaprakları ve plastik bardakların birlikte pirolizinden üretilen piroliz çarının bitümün viskozitesi ve yüksek sıcaklık performans sınıfı üzerine etkileri araştırılmıştır. Bu amaçla, 50/70 penetrasyon bitüm, üretilen piroliz çarı ile %6 ve %12 oranlarında modifiye edilmiştir. Modifiye bitümler ve saf bitüm numuneleri üzerine yumuşama noktası deneyi, penetrasyon deneyi, dinamik kesme reometresi (DSR) deneyi ve dönel viskozite (RV) deneyi yapılmış, ayrıca PI değerleri belirlenerek katkı maddesinin bitümün sıcaklık hassasiyetine etkisi değerlendirilmiştir. Sonuç olarak, %6 ve %12 oranında katkı maddesi olarak kullanılan piroliz çarının saf bitümün viskozitesini 135°C de yaklaşık sırasıyla %33 ve %83 oranlarında arttırdığı, 70°C de tekerlek izi direncini sırasıyla %46 ve %24 oranında arttırdığı ve saf bitümün yüksek sıcaklık PG sınıfını arttırdığı tespit edilmiştir.
