Bitümün farklı polimerler ile modifikasyonu, polimerin tipi, bitüm bileşenleri ve karışım koşulları gibi faktörlere bağlı olarak, reolojik ve kimyasal karakterizasyon farklılıklarına neden olur. Anahtar parametreler olarak da adlandırılabilen karışım koşulları; karıştırma sıcaklığı, karıştırma süresi, kesme oranı (karıştırma hızı) gibi alt başlıklarla incelenebilir. Polimer Modifiye Bitüm (PMB) karışım koşulları, ya da diğer bir deyişle anahtar parametreler, malzemenin yaşlanma özellikleri, polimerin degredasyonu ya da polimerin bitüm tarafından emilimi gibi PMB karakterizasyonu üzerinde önemli etkilere sahiptir ve bu sebeple araştırmacılar için her zaman ilgi çekici bir konu olmuştur. Bu çalışma, literatürde şimdiye kadar gerçekleştirilmiş ve PMB’nin üretiminde karışım koşullarının etkisini ortaya koyan yayınların derlemesini sunarak anahtar parametrelerin önemini ortaya koymayı amaçlamaktadır.

Modification of bitumen by different modifiers, causes the morphological, rheological and chemical characterisation differences related to the following three main factors: the type of the polymer, bitumen components and blending conditions. Manufacturing conditions can be investigated in several groups such as; mixing temperature, duration of mixing and shear rate (mixing speed). These manufacturing conditions are the key parameters, since they act an important role on the properties of the final product. These key parameters and their effects have always been an interesting topic for the researchers, because they may have some consequences like aging of the sample, degradation of the polymer or sometimes less absorption of the polymer by bitumen etc. This study aims to present the influences of mixing conditions on different properties of the bituminous mixtures with the help of reviewing the previous studies in the literature.
