Abstract (2. Language): 
In this study, it was aimed to develop the properties of 50/70 penetration grade bitumen with organic-based synthetic zincphosphate compound (OBZPC). OBZPC is a new additive material that is synthesized within the scope of the study and has not been used as bitumen modifier before. The effects of OBZPC on the bitumen and bituminous mixture properties were investigated through conventional (softening point test, ductility test, Marshall test, Nicholson stripping test) and superpave (rotational viscosity, bending beam rheometer, dynamic shear rheometer) test methods. OBZPC was added to the bitumen at the ratios of %1, %2, %3, %5, %10 by mass and OBZPC concentration ratio to be used in the modification of bitumen was selected as %3 by evaluating the viscosity test results. The low temperature rheological properties of the bitumen were determined to be improved by OBZPC modification. In addition to this, 3% OBZPC concentration has increased Marshall stability of the bituminous mixtures by %6,1 and upgraded stripping resistance from %30 to %95.

Abstract (Original Language): 
Bu çalışmada 50/70 penetrasyon dereceli bitüm özelliklerinin organik esaslı sentetik çinkofosfat bileşiği (OEÇFB) ile modifiye edilerek geliştirilmesi amaçlanmıştır. OEÇFB, çalışma kapsamında sentezlenmiş yeni bir katkı malzemesidir ve bitüm modifiyeri olarak daha önce kullanılmamıştır. OEÇFB’nin bitüm ve bitümlü karışımlar üzerindeki etkisi konvansiyonel (yumuşama noktası testi, düktilite testi, Marshall testi, Nicholson soyulma testi) ve superpave (dönel viskozite, eğilme kirişi reometresi, dinamik kayma reometresi) test metotları ile incelenmiştir. OEÇFB, bitüme kütlece %1, %2, %3, %5, %10 oranlarında ilave edilmiş ve viskozite test sonuçları değerlendirilerek bitüm modifikasyonunda kullanılacak OEÇFB konsantrasyonu %3 olarak seçilmiştir. Bitümün düşük sıcaklıklardaki reolojik özelliklerinin OEÇFB modifikasyonuyla iyileştiği belirlenmiştir. Bununla birlikte %3’lük OEÇFB konsantrasyonu bitümlü karışımların Marshall stabilitesini %6,1 arttırmış, soyulma direncini %30’dan %95’e yükseltmiştir.
