Abstract (2. Language): 
In this study, the Taguchi method, a powerful tool to design optimization for quality, is used to determine the optimal conditions for concrete pavement with fly ash and silica fume. An orthogonal array (L16 with four factors with four levels each), the signal-to-noise (S/N) ratio, and the Analysis of Variance (ANOVA) are employed to investigate the compressive strength. 0.30, 0.35, 0.40 and 0.45 water/binder ratios, four different types of gradation with maximum aggregate size of 32mm, 0, 5, 10 and 15% fly ash and 0, 10, 20 and 30% silica fume replacement by weight of cement are the levels of factors. According to the results of ANOVA, water/binder ratio and type of gradation plays significant role for compressive strength of concrete pavement. In addition, the optimum conditions were found to be 0.30 water/binder ratio, Type IV gradation (70% coarse aggregate, 30% fine aggregate), 5% FA content and 10% SF content. Maximum compressive strength of 66.83 MPa was achieved at the optimum conditions.

Abstract (Original Language): 
Bu çalışmada, uçucu kül ve silis dumanı ile üretilen yol betonlarının basınç mukavemetleri Taguchi metodu kullanılarak optimize edilmiştir. Basınç mukavemetini araştırmak için L16 ortogonal dizisi (her biri dört seviyeli dört faktör), sinyal/gürültü oranı (S/N) ve varyans analizi kullanılmıştır. Faktörler ve seviyeleri olarak 0.30, 0.35, 0.40 ve 0.45 su/çimento oranı, maksimum dane çapı 32 mm olan dört farklı gradasyon, çimento ağırlığının 0, 5, 10 ve 15% uçucu kül ve 0, 10, 20 ve 30% silis dumanı kullanılmıştır. ANOVA tablosuna göre, yol betonlarının basınç mukavemetleri üzerine su/çimento oranı ile gradasyon tipinin çok büyük etkisinin olduğu görülmüştür. Bununla birlikte, optimum şartlardaki faktör ve bunların seviyeleri ise 0.30 su/çimento oranı, IV tip gradasyon (70% iri agreega, 30% ince agrega), 5% uçucu kül içeriği ve 10% silis dumanı içeriği olarak bulunmuştur. Optimum şartlarda maksimum 66.83 MPa’lık basınç mukavemeti elde edilmiştir.
