In Turkey, highway pavement is generally constructed using bitumen binders. Bitumen binders are not only imported materials but also easily affected by external factors. Bitumen pavement has shorter service duration compared concrete pavement and also it requires enormous repair. Since concrete pavement has higher strength and durability compared to bitumen pavement, concrete pavement has to be used as an alternative pavement material. In this study, Soma and Afsin-Elbistan thermic plant ashes, substituted up to 40% of cement, were used to produce concrete pavement material and its properties were investigated. Although the investigation was conducted in the laboratory, samples were provided to remain under the same condition with actual highway pavement. As a result, the concrete pavement material produced with 30% substituted fly ash in place of cement had the same strength with reference concrete and at later age its strength was higher than reference concrete strength. In addition, concrete pavement material with fly ash showed sufficient strength and durability to varieties of mechanical and chemical effects.
