and subsequent adjustments. From the example on the next page (Figure 37) it can be seen that the
available data has been plotted on a graph of corrected CBR versus molded dry density for constant
moisture contents. For low molding water contents (i.e., from 10 to 12 percent) there was an increase in
strength with dry density, and at high moisture contents (i.e., 16, 17, and 18 percent), the reverse was
found to be true. For the intermediate moisture contents, there was an increase in strength to some
point, and then a decrease as the dry density increased.
