Determine the quantity of asphalt and granular material required for the parking lot shown in Figure 10.60. The asphalt is 4 inches thick and the granular material is 8 inches thick.
What will be an ideal response?
Ignoring the small radius, the area of the parking lot is calculated as follows:
Main area = 200? × 99? = 19,800 sf
Drive area = 23? × 24? = 552 sf
Total area = 19,800 sf + 552 sf = 20,352 sf
From Figure 10-44 of the textbook, the parking lot will require 26.0 tons of asphalt and 42.0 tons of granular material per 1,000 sf.
Asphalt = 26.0 tons per 1,000 sf of 4? thick × 20.352 thousand sf = 529 tons
Asphalt = 42.0 tons per 1,000 sf of 8? thick × 20.352 thousand sf = 855 tons
