The California Bearing Ratio (CBR) test determines behaviour of road sub-base and granular layers for flexible pavement. In the conventional CBR test, compacted sample was waited in air for 24 h and in water for 4 days. In this study, the fresh and 28 days curing effects were examined and pH values were measured end of 28 days curing on the CBR percent of soils stabilized with F class fly-ash and cement. There are two main matrix material in this study. One of the matrices consists of Bilecik Clay and Lime and other consists of Bilecik Clay, Bentonite and Lime. In samples, fly-ash (Class-F) and cement were used as additives. Different mixtures which were obtained with various combinations of these materials were prepared and end of compaction were cured in various moulds depending on test. The mechanical strength test as wet CBR, triaxial and unconfined strength tests were performed on the mixtures and physical characteristics as CBR percent and chemical characteristic as pH values were measured.
