Experimental Investigation of Common Effectiveness of Fine Aggregate, Cement, and Compressive Strength of Optimum Mix Design of Pavement Rolled Compacted Concrete

The need for a suitable Roller Compacted Concrete Pavement (RCCP) 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 RCC’s gradation in 8 different types, inside and outside the specified range of regulations, and 5 different percentages of cements, compressive strength of the 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 and optimal compressive strength. The concrete compressive strength of Rolled Compacted Concrete was increased by increasing the cement up to limited amount .
