Length of project in feet.
Width of project in feet.
Pounds per square yard of asphalt per
1-inch depth. (Example: A 2-inch mat
will equal 220 pounds per square yard.)
To obtain square yards from square feet,
divide by 9.
2,000 pounds equal one ton; therefore, you
must divide the total weight of material by
2,000, giving tons required.
Waste factor equals 5% 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
Find the amount of asphalt required for this project.
Placing Plant-Mix Materials
The material that arrives at the construction site
from the plant must be spread. It must cover the entire
