Hi

Here is my problem. I've been given this project and I'm really not sure how to approach it. The image shows a road intersection. I need to figure out the quantity of road asphalt required to pave this roadway with 50mm of asphalt. The corner radius have been given to me as '4m radius' and the asphalt density as 2.5. The circle is imaginary, I've simply included this to help me with my calculation.

1st I calculate the total road area less the radius.

6 x 14m =84m2

4 x 6m=24m2

4 x 6m=24m2

Total area 132.0m2

2nd I calculate the radius for 1 corner.

4 x 4m = 16m2

less the area of the circle 3.1416 x 2 x 2 = 12.5664m2

the radius area = 3.4336m2 x 4 = 13.7344m2 + 132.0m2

Grand Total Area =145.7344m2

Now I need to calculate the quantity of asphalt to cover this area at 50mm. So I need to covert the 50mm to meters(?)

50mm/1000 = 0.05

Now this is where I get lost. Is this the formula I use? area x depth x density?

145.7344 x 0.05 x 2.5 = 18.2168 mg

Any help will be greatly appreciated.
