How many tons of asphalt concrete will be required to overlay a 2.5 mile long 24 ft wide road with 3in of wearing course asphalt concrete that has a density of f 147.9PCF?

To determine the weight of the asphalt needed, first determine the area of the surface to be paved.

Since the shape of the road is a rectangle, use the formula of area of rectangle.

A = Length xx Width

Before plugging-in the values, convert the 2.5 miles to feet in order that the dimension to have same unit.

So,

2.5 mi xx (5280 ft)/(1mi) = 13200ft

Now that the length is in feet, plug-in the values of dimension of the road to the formula of area of rectangle.

A=13200*24

A=316800

Hence, the area to be paved is 316 800 ft^2 .

Next, determine the volume. Use the formula:

V = Area xx thickness

Before substituting the values, convert the thickness to feet in order to have same units.

So,

3 i n xx (1ft)/(12 i n)=0.25ft

Then, substitute the values of the area and thickness to the formula of volume.

V=316800*0.25=79200

Thus, the volume of the asphalt needed is 79200 ft^3.

Next, to determine its weight , multiply that with the given density 1479 pounds per cubic feet (1479 lb/ft^3).

W=79200*1479=117136800

So, the weight is 11 7136 800 lbs.

Then, convert it to tons.

117136800 lbs xx (1t o n)/(2000lbs) = 58568.4 t o n s
