Bu çalışmada karayollarında sıklıkla kullanılan bazalt, kaba-ince agrega ve kontrol filler olarak kullanılmıştır. Alternatif filler malzemesi olarak kalker ve volkanik cüruf kullanılmıştır. Agregalara fiziksel, kimyasal ve mekanik özellik tayini yapıldıktan sonra uygun gradasyonda %4,5, 5, 5,5, 6, 6,5 oranlarında bitüm kullanılarak Marshall stabilite deneyi yapılmıştır. Her bitüm yüzdesinde 3 numune olmak üzere toplam 45 numune döküm yapılmıştır. Optimum bitüm yüzdesi belirlendikten sonra bazalt, kalker ve volkanik cüruf fillerin kullanıldığı numuneler karayolları teknik şartnamesine göre kıyaslanmıştır. Çalışma sonucunda kalker fillerin, optimum bitüm oranını düşürmesi, metilen mavisi deney sonucuna göre sınır değeri aşmaması ve bölgede kalker ocaklarının çok sayıda bulunması nedeniyle alternatif filler olarak kullanılabileceği saptanmıştır.
In this study, it was often used on the roads as basalt, brutal-thin agrega and control elephants. Alternative elephant material is used as calker and volcanic curve. After the determination of the physical, chemical and mechanical characteristics of the aggregates, the Marshall stability experiment was performed using bits at 4.5%, 5, 5,5, 6, 6,5% in the appropriate grade. A total of 45 samples were cast in each bit percentage of 3 samples. After the optimum bitum percentage was determined, the samples used by basalt, calker and volcanic crawler were compared according to the technical specifications of the road. The study found that the calker flies could be used as alternative flies due to the lowest optimum bitum rate, the methylene blue test result does not exceed the limit value and the abundant number of calker flies in the area.
In study, basalt, which is frequently used in highways, was used as coarse-fine aggregate and control filler. Limestone and volcanic slag were used as alternative filler materials. After determining the physical, chemical and mechanical properties of the aggregates, Marshall stability test was carried out using bitumen at the rate of 4,5, 5, 5,5 6, 6,5% in appropriate gradation. A total of 45 samples were casted as 3 samples per bitumen percentage. After determining the optimum bitumen percentage, used samples basalt, limestone and volcanic slag were compared according to the highway technical specifications. As a result of the study, it was determined that limestone fillers can be used as alternative fillers because they reduce the optimum bitumen rate, do not exceed the limit value according to the methylene blue test result and there are many limestone quarries in the region.
