Abstract (2. Language): 
This paper describes the determination of shape and surface texture characteristics of different mineralogical type and shape (both angular and round) of fine aggregates which were received from fourteen different sources. The ASTM C1252 methods (methods A, B, and C) were used to determine the uncompacted void content of fine aggregates. The compacted aggregate resistance (CAR) test was also conducted on the same group of fine aggregates with as received and standard gradation as well as on the aggregate blends (M0, M25, M50, M75, M100) to provide a more performance-based aggregate parameter. In this way, the CAR test and ASTM C 1252 methods for evaluating the shape and surface texture characteristics of fine aggregates can be compared.
Abstract (Original Language): 
Bu çalışma, farklı mineralojik köken ve şekil özelliklerine sahip 14 farklı kaynaktan temin edilen ince agregaların şekil ve yüzey pürüzlülüğü özelliklerinin belirlenmesini kapsamaktadır. Bu amaçla, ASTM C1252 yöntemleri (yöntem A, B ve C) ince agregaların sıkışmamış boşluk yüzdelerini belirlemede kullanılmıştır. Aynı agregalar ve agrega karışımları (M0, M25, M50, M75, M100) üzerinde, standart boyut dağılımında ve ocaktan alındıkları hali ile sıkıştırılmış agrega dayanımı (CAR Test) deneyleri uygulanmıştır. Böylece, ince agregalarda şekil ve yüzey pürüzlülüğü özelliklerinin değerlendirmekte kullanılan CAR Test ve ASTM C1252 deney yöntemleri karşılaştırılabilecektir.
