6.0-inch RCC pavement without an HMA overlay is equal to a 5.5-inch RCC pavement with an approximately 1.4-inch HMA overlay. Also from Figure 4, a 5.0-inch RCC pavement with an approximately 2.5-inch HMA overlay is equal to the unsurfaced 6.0-inch RCC pavement. Finally, Table 2 gives various design options for traffic conditions
cement concrete (RCC) is an ideal structural material for building of permanent bulk storage facilities. RCC Bin can be flat bottom type or hopper bottom type. Although flat bottom bins can be built more easily than hopper bottom bins but it is desirable that bottom is self cleaning. It is because of this
