Atık polimerler
ekonomik malzemeler olmalarına karşın karayolları gibi geniş bir uygulama
alanında katkı malzemesi olarak değerlendirilmeleri durumunda, bitümlü
bağlayıcılarla kimyasal etkileşime girmemekte dolayısıyla esnek üstyapı
içerisinde kullanımları sınırlı hale gelmektedir.

Çalışma kapsamında,
geri dönüştürülmüş polipropilen (PP_R), gamma ışıması ile radyasyona
tabi tutularak polimer üzerinde yeniden kimyasal bağ oluşturabilecek serbest
radikaller meydana getirilmiştir. Ağırlıkça %1, %3, %5, %7 ve %9 katkı
oranlarında hazırlanan modifiye bitümler üzerinde FT-IR spektroskopisi, floresan
mikroskobu, geleneksel test yöntemleri, kısa ve uzun vadeli yaşlandırma
işlemleri, dönel viskozite, dinamik kayma reometresi ve kiriş eğme reometresi
deneyleri yapılarak katkının bitüm içerisinde kullanımı kimyasal ve fiziksel
yöntemlerle incelenmiştir.

Usage of Recycled Postconsumer Polypropylene in Bituminous Binder

Öz

Although waste polymers are economical
materials, they are limited, in the case of a wide usage in highway application
due to no chemical interaction between them and bituminous binders.

In this work, recycled polypropylene was
exposed to gamma irradiation to form free radical on the polymer surface. Five
different samples of modified bitumen were prepared with the modifier content,
wt. 1, 3, 5, 7 and 9% and binders were investigated in term of chemical and
physical properties by means of FT-IR spectroscopy, florescent microscope,
conventional tests, short and long term aging procedures, rotational viscosity,
dynamic shear and bending beam rheometer tests.
