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
