Optimization of concrete mixing design is one of the important concerns of researchers in this filed. So far, various methods have been developed to optimize and predict the effect of aggregate characteristics and enhance the properties of concrete mixtures. Many efforts have been made to optimize the concrete mix. But it cannot be claimed that such a technique has been proposed so far. Each proposed method and model have its own advantages and limitations. This can lead to time, a large amount of design testing (EOD), the magnitude of approximate errors, the invalidity of areas outside the scope of the factors under review, and ultimately cost-effectiveness. The strength and durability of concrete in many cases be subject to on variables such as mix ratio, aggregates properties and characteristics, coarse and fine aggregate ratio, compaction method, curing period, gradation, packaging density, and wherein effect the strength and durability of fresh and hardened concrete. Combined Graphical Method (CGM) is a combination of traditional and modern concrete optimization methods which has a special emphasis on the properties and characteristics of the aggregates. This method is intended for concrete pavement mix to determine the C / F ratio consisting of coarse aggregates of 10, 20 and 38 mm and fine aggregates including river sand and mine.
