Determine the quantity of asphalt and granular material required for the parking lot shown in Figure 10.61. The asphalt is 3 inches thick and the granular material is 6 inches thick.
What will be an ideal response?
Ignoring the small radius, the area of the parking lot is calculated as follows:
Main area = 227? × 146? = 33,142 sf
Drive area = 12? × 23? = 276 sf
Total area = 33,142 sf + 276 sf = 33,418 sf
From Figure 10-44 of the textbook, the parking lot will require 19.5 tons of asphalt and 31.5 tons granular material per 1,000 sf.
Asphalt = 19.5 tons per 1,000 sf of 3? thick × 33.418 thousand sf = 652 tons
Asphalt = 31.5 tons per 1,000 sf of 6? thick × 33.418 thousand sf = 1,053 tons
