ÖĞÜTÜLMÜŞ ARAÇ LASTİĞİNİN VE PİROLİZ İŞLEMİNDEN SONRA OLUŞAN KARBON SİYAHININ BİTÜMLÜ BAĞLAYICILARIN REOLOJİK ÖZELLİKLERİ ÜZERİNDEKİ ETKİSİ
Abstract
Bu çalışmada iki farklı boyutta (No.40 elek üstü ve altı) öğütülmüş araç
lastiği (CR) ve öğütülmüş araç lastiğinin pirolizinden elde edilen karbon
siyahı bitüm modifikasyonunda 3 farklı oranda (%5, %10 ve %15) kullanılmıştır.
Saf ve modifiye bağlayıcılar üzerinde penetrasyon, yumuşama noktası, viskozite
ve dinamik kayma reometresi (DSR) deneyleri uygulanmıştır. Ayrıca
bağlayıcıların ısıya karşı hassasiyetinin göstergesi olan penetrasyon indeksi
(PI) değerleri belirlenmiştir. Penetrasyon, yumuşama noktası ve viskozite
deneyleri sonucunda bitüm modifikasyonunda kullanılan CR miktarı arttıkça
penetrasyon değerlerinin düzenli olarak azaldığı, yumuşaman noktası ve
viskozite değerlerinin düzenli olarak arttığı belirlenmiştir. Bu durum CR
kullanımı ile bitümün rijitliğinin arttığını göstermektedir. CR boyutu
değerlendirildiğinde malzeme boyutunun bu üç deney üzerinde önemli bir etkiye
sahip olmadığı belirlenmiştir. PI değerlerinden saf bağlayıcıya kıyasla No.40
elek altı %5 CR kullanılan modifiye bitüm dışındaki tüm modifiye bitümlerin
ısıya karşı hassasiyetinin daha az olduğu belirlenmiştir. DSR deneyleri
sonucunda CR içeriği arttıkça bağlayıcıların tekerlek izine karşı dayanım
parametrelerinin ve elastikiyetlerinin arttığı belirlenmiştir. Öğütülmüş CR’nin
pirolize tabi tutulmasından elde edilen karbon siyahının bitüm modifikasyonunda
kullanılması, CR’nin etkinliğini azaltmış özellikle No.40 altı boyuttaki CR’nin
karbon siyahı saf bitümün özelliklerini iyileştirme özelliği göstermemiştir.

Effects of Crumb Rubber and Carbon Black Obtained from Pyrolysis of Crumb Rubber on the Rheological Properties of Bituminous Binders
Abstract
In this study,
two different sizes (smaller and larger sizes of No.40 sieve) of crumb rubber
(CR) and the carbon black, which was acquired as a result of the pyrolysis of
crumb rubber, were employed in the bitumen modification with 3 different rates
(5%, 10% and 15%). Penetration, softening point, rotational viscometer and
dynamic shear rheometer (DSR) tests were carried out on both pure and modified
binders. Additionally, penetration index (PI) values, which is an indicator of
binders against thermal sensitivity, were determined. As a result of
penetration, softening point and viscosity tests, it was observed that with the
increase of CR used in the bitumen modification, the penetration values
decreased, and softening points and viscosity values increased regularly. This
condition indicates that the stiffness of the bitumen increases with CR
utilization. In the evaluation of the sizes of CR, it was determined that the
sizes of the materials had no considerable effect on these three tests. In the
PI values, it was concluded that thermal sensitivities were lower compared to
pure bitumen, except in the 5% CR with smaller sizes of No.40. As a result of
the DSR test, it was concluded that with the increase of CR content, the
parameters of binders in the resistance against rutting and their elasticity
were increased. The utilization of carbon blacks, which obtained from the
pyrolysis of CR, in the bitumen modification reduced the effectiveness of CR
and especially the carbon black from smaller sizes of No.40 CR demonstrated no
improvement in the properties of pure bitumen.
