Abstract
The need for a suitable roller Compacted concrete has effective role in the use of this concrete in the pavement. In order to achieve the desired roller Compacted concrete, an optimal mixing plan is required to have optimal mixing parameters such as kind of stone materials, type of aggregate, type and amount cement consumption and other properties of its ingredients can play a significant role. In this paper, by changing the roller concrete gradation in 8 different types, inside and outside the specified range of regulations, and 5 different percentages of cements, compressive strength of cylindrical samples were tested and calculated to determine the optimal amount of cement and optimum granulation. The results of this experiment showed that the mixing plan with 34% fine grained and 66% coarse presented the best compressive strength. The concrete compressive strength of Rolled Compacted Concrete was increased by increasing the cement up to limited amount .
