Farklı Tür Agregalarla Üretilen Yüzeysel Kaplamaların Kayma Direnci Performanslarının İncelenmesi

Bu çalışmada, doğal agregalardan ve cüruflardan oluşan farklı agrega tür ve tane boyutlarında ve gradasyonunda üretilen yüzeysel kaplamaların kayma direnci performansı araştırılmıştır. Bu amaç doğrultusunda, öncelikle her bir agreganın fiziksel, mekanik ve kimyasal özelikleri TS EN standartlarına göre belirlenmiştir. Sathi kaplama örnekleri; 2-19 mm aralığında değişen yedi farklı tane boyutunda hazırlanırken, harç tipi kaplama örnekleri ise üç farklı gradasyonda üretilmiştir. Üretilen yüzeysel kaplama numunelerinin, kayma dirençleri ve makro dokuları sırasıyla ASTM E 303 ve ASTM E 965 standartları göre belirlenmiştir. Yüzeysel kaplamaların kayma direnci karşılaştırıldığında, her boyut ve gradasyonda cüruflar ile üretilmiş olan numunelerin, doğal agrega ile üretilmiş olan numunelerden daha iyi performans gösterdiği gözlenmiştir

Evaluation of Skid Resistance Perfromance of Surface Coatings Manufactured with Different Aggregates

In this study, skid resistance performance of surface coatings, which were produced with different aggregate types including natural aggregates and slags and sizes and gradations were evaluated. Physical, mechanical and chemical properties of each aggregate were determined according to related EN standards. Chip seal samples were prepared with seven different particle size ranging from 2.00 to 19.00 mm, whereas slurry seal samples were manufactured in three different gradations, which are specified in ASTM D 3910. To identify the skid resistances and macro-textures of each surface coating samples, ASTM E 303 and ASTM E 965 were followed. The results showed that skid resistance performance of the samples manufactured with slags higher that those produce with natural aggregates
