Harç Tipi Kaplamalardaki Farklı Mineral Filler Oranlarının Viskozite Üzerine Etkisi

Harç tipi kaplamalar, yol kaplama yüzeylerinde kullanılan koruma yöntemlerinin en önemli uygulamalarından biridir. Harç tipi kaplamalar, agrega, bitüm emülsiyonu, su, mineral filler (çimento vb.) ve bazı katkı malzemelerinden oluşur. Bu malzemelerin oranları viskozite parametresinde önemli bir rol oynar. Bu çalışmada, Standard Test Method for Viscosity Determination of Asphalt (ASTM D 4402-15 2015) yöntemi kullanılarak harç tipi kaplama numunelerindeki viskozite değişimi üzerine laboratuvar araştırması yapılmıştır. Sonuç olarak, farklı mineral filler oranlarına sahip harç tipi kaplama numunelerinin farklı viskozite değerlerine sahip olduğu bulunmuştur.

Effect of Different Mineral Filler Ratios on Viscosity in Slurry Seal Mixtures

Slurry seal and Microsurfacing are one of the most significant applications of pavement preservation methods on highway surfaces. The slurry seal mixtures consist of aggregate, bitumen emulsion, water, mineral filler (cement etc.), and some additives. The appropriate amounts of these materials play an important role in viscosity. In this study, laboratory research was performed to understand the viscosity changing in slurry seal samples according to Standard Test Method for Viscosity Determination of Asphalt (ASTM D 4402-15 2015). As a result, slurry seal samples prepared with different mineral filler ratio have different viscosity values.
