A significant factor in selecting a typical sample unit size
Thus, the last sample unit has an area of 22 x 120 or
for a section is convenience. For example, an asphalt
2640 square feet. The above example is shown in figure
pavement section that is 22 feet wide by 4720 feet long
can be divided into sample units that are 22 feet wide by
(2) A schematic diagram of each section
100 feet long, or 2200 square feet. The last sample units
(such as that shown in figure 2-5) will be made showing
of the section may have to be of different lengths
the size and location of its sample units. These sketches
because of the length of the section. In the above
are required for future inspections to relocate the sample
example, the section is divided into 46 units that are
each 100 feet long and one unit that is 120 feet long.
