If a concrete pavement is to be paved at a rate of 200 ln.m at half width per paving day, how many sets of concrete beam samples will be required for A = 115,000 sq.m, width = 6.50 m, and thickness = 230 mm?

To determine how many sets of concrete beam samples are required, we can start by calculating the total volume of concrete needed for the pavement project and then use the specifics of the pavement design to find out how many beam samples are necessary.

First, calculate the area of the pavement. With an area of 115,000 sq.m and a width of 6.50 m, we find the volume by multiplying the area by the thickness (in meters). The thickness of 230 mm is equivalent to 0.23 m.

Volume (V) = Area (A) × Thickness (T)

V = 115,000 sq.m × 0.23 m = 26,450 cubic meters.

Next, examine the paving rate. The concrete pavement is paved at a rate of 200 linear meters at half width daily. The half width is 6.50 m / 2 = 3.25 m. Therefore, the area paved per day can be calculated as:

Area per day = Paving rate × Half width

Area per day = 200 m × 3.25 m = 650 sq.m.

To find out how many days it will take to complete the pavement, divide the total area by the area
