Farklı oranlardaki poliolefin polimer karışımları ve SBS kopolimerinin bitümün viskozitesine ve sıcaklık hassasiyetine etkilerinin karşılaştırmalı olarak değerlendirilmesi

Bu çalışmada, farklı oranlardaki poliolefin karışımlarının (polipropilen(PP):polietilen(PE)) saf bitümün viskozitesine ve sıcaklık hassasiyetine etkisinin belirlenmesi ve SBS (stiren-butadiyen-stiren) modifiye bitümler ile karşılaştırmalı olarak değerlendirilmesi amaçlanmıştır. Bu amaçla, saf bitüm farklı oranlardaki poliolefin karışımları (PP:PE) ve ayrıca %2SBS, %4SBS ve %4PP ile modifiye edilmiştir. Polimerlerin saf bitüm üzerindeki etkilerini değerlendirmek için tüm bağlayıcıların viskozite, yumuşama noktası, penetrasyon, sıcaklık hassasiyeti ve karıştırma-sıkıştırma sıcaklık değerleri belirlenmiştir. 135°C’deki deney sonuçları, 3:1 PP:PE ve 1:3 PP:PE katkılı bitümlerin viskozitelerinin, %2SBS ve %4PP modifiye bitümlerin viskozite değerlerinden daha yüksek olduğunu göstermiştir. %4 SBS katkılı bitümün en az sıcaklık hassasiyetine ve 135°C’de en yüksek viskozite değerine sahip bağlayıcı olduğu görülmüştür. 135°C’de tüm bağlayıcıların viskozitelerinin 3 Pa s şartname kriterini aşmadıkları tespit edilmiştir. 3:1 PP:PE modifiye bitümün diğer poliolefin katkılı bitümlerden ve %2SBS modifiye bitümden daha az sıcaklık hassasiyetine sahip bağlayıcı olduğu belirlenmiştir. Sonuçlar, tüm polimer modifiye bitümler arasında %2SBS katkılı bitümün en düşük karıştırma-sıkıştırma sıcaklıklarına sahip bağlayıcı olduğunu göstermiştir.

Comparatively evaluation of the effects of polyolefin polymer blends in different ratios and SBS copolymer on viscosity and temperature susceptibility of bitumen

In this study, it was aimed to detect the effects of different polyolefin mixtures (polypropylene(PP): polyethylene(PE)) on the viscosity and temperature susceptibility of pure bitumen and was also aimed to comparatively evaluate with SBS (styrene-butadiene-styrene) modified bitumens. For this purpose, bitumen was modified with different polyolefin mixtures (PP:PE) and was also modified with 2%SBS, 4%SBS and 4%PP. To evaluate the effects of polymers on pure bitumen, viscosity, softening point, penetration, temperature susceptibility and mixing-compaction temperature values of all bituminous binders were detected. The test results at 135°C showed that, the viscosities of 3:1 PP:PE and 1:3 PP:PE modified bitumens were higher than the viscosities of 2%SBS and 4%PP modified bitumens. It was seen that, 4%SBS modified bitumen was the binder with the lowest temperature sensitivity and the highest viscosity at 135°C. It was detected that the viscosities of all binders at 135°C did not exceed the 3 Pa s specification criterion. It was determined that, 3:1 PP:PE modified bitumen was a binder with a lower temperature sensitivity than other polyolefin modified bitumens and 2%SBS modified bitumen. Results showed that 2%SBS modified bitumen was the binder with the lowest mixing-compaction temperatures among all of the polymer modified binders.
