Effect of Bentonite Nanoclay on Storage Stability of Elastomeric and Plastomeric Polymer Modified Bitumens

Abstract

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

Abstract

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.
