Polimer modifiyeli asfalt karışımların neme duyarlılığı üzerine agrega ve ılık karışım asfalt katkılarının etkileri

Abstract

Bu çalışmada, agrega ve ılık karışım asfalt katkılarının modifiye edilmemiş ve polimer modifiyeli asfalt karışımlarının nem hasarı özellikleri üzerindeki etkileri incelenmiştir. Karışımların neme duyarlılığını değerlendirmek amacıyla AASHTO T283 yöntemi kullanılmıştır. Asfalt karışımlarının üretimi için FT-parafin ve Montan vaks, modifiye edilmemiş ve polimer modifiyeli bitüme ilave edilmiştir. Çalışmada farklı kaynaklardan elde edilen dört kırmataş agrega kullanılmış olup, bunlardan ikisi yüksek oranda silisyum dioksit (SiO₂), diğer ikisi ise yüksek oranda kalsiyum oksit (CaO) içermektedir. FT-parafin ve Montan vaksları, hem modifiye edilmemiş hem de polimer modifiyeli bitümün üretim ve sıkıştırma sıcaklıklarını yaklaşık 10°C düşürmüştür. Araştırma sonuçları, agrega kaynağının ve polimer modifikasyonunun karışımların dolaylı çekme dayanımı oranları üzerinde önemli bir etkiye sahip olduğunu göstermiştir. Ayrıca, agregaların kimyasal bileşiminin karışımların neme duyarlılığı ile ilişkili olmadığı belirlenmiştir. Bu nedenle, karışımda kullanılacak agreganın kaynağı dikkate alınmalıdır.

Impacts of aggregate and warm mix asphalt additives on the moisture susceptibility of polymer-modified asphalt mixtures

Abstract

The impacts of aggregates and warm mix asphalt additives on the moisture damage characteristics of unmodified and polymer-modified asphalt mixtures were examined in the current study. AASHTO T283 procedure was employed for the purpose of assessing the moisture susceptibility of mixtures. For the production of asphalt mixtures, FT-paraffin and Montan wax were added to unmodified and polymer-modified bitumen. In the current study, four crushed aggregates from different sources were used, two of which contain a high percentage of silicon dioxide (SiO2) and the other two contain a high percentage of calcium oxide (CaO). FT-paraffin and Montan wax reduced the production and compaction temperatures of both unmodified bitumen and polymer-modified bitumen by about 10°C. The results of the research show that the source of aggregate and polymer modification had a significant impact on the mixtures' indirect tensile strength ratios. The results also show that the chemical composition of the aggregates is not related to the moisture susceptibility of the mixtures. Hence, source of the aggregate to be utilized in the mixture should be taken into account.
