Overlay Example – US Customary Units
In this example, the bottom layer density (left scale) is 130 pcf
with a mat 1.2 inches thick overlaying it. A backscatter density
test on the top of the mat (right scale) yielded a result of 138.5
pcf. A line is then drawn from 130 pcf on the left scale through
the intersection of 1.2 inches (bottom) and 138.5 pcf (right) and
extended to the right.
The correct density for the top layer is then read from the
nomograph as 144.5 on the right scale.
