Table 8-6.-Weight and Volume Relations for Various Types of Compacted Asphalt Pavement.
110 = Pounds per square yard of asphalt per 1
inch depth. (Example: A 2-inch mat will
equal 220 pounds per square yard.)
9 = To obtain square yards from square feet,
divide by 9
2,000 = 2,000 pounds equal one ton; therefore,
you must divide the total weight of
material by 2,000, giving tons required.
WF = Waste factor equals 570 or .05, or 10% or
.10, depending on the experience of the
screed operators, and handwork required
on the project.
Example: The specifications for a parking lot
paving project are as follows:
L = 90 feet
W = 30 feet
D = 2 inches
WF = .10
