Bentonit Nanokilinin Elastomerik ve Plastomerik Polimer Modifiye Bitümlerin Depolama Stabiliteleri Üzerindeki Etkisi

Öz

Polimerlerin bitüm ile uyumu ve
modifikasyon süreci modifiye bitümün ve nihai asfalt karışımın özellikleri
üzerinde anahtar rol oynamaktadır. Bu çalışmanın amacı elastomer ve plastomer
türü polimer modifiye bitümler üzerinde bentonit nanokilinin etkisinin
morfolojik yönden araştırılmasıdır. Bu amaçla, SBS, SEBS, SIS elastomerleri ile
EVA ve EBA plastomerleri %5 oranında kullanılarak nanokil içermeyen ve %3
oranında nanokil içeren polimer modifiye bitümler hazırlanmıştır. Polimer
modifiye ve polimer/nanokil modifiye bitümlere depolama stabilitesi deneyi
yapıldıktan sonra örnekler optik mikroskop ve taramalı elektron mikroskobu
(SEM) yöntemleri ile değerlendirilmiştir. Nanokil kullanılarak elastomerik ve
plastomerik polimer modifiye bitümlerin depolama stabilitelerinin iyileştirilebileceği
görülmüştür.
