Determine the percentage asphalt content (AC) for each Marshall property. Go to Table 9,

column 4, High Pressure, to find where to enter the graph.

peak of the curve a vertical line is drawn down to the percent AC line. In this case the reading

for maximum stability is approximately 4.3 percent (Figure 14).

peak of the curve a vertical line is drawn down to the percent AC line. Figure 15 shows that the

reading for maximum unit weight in this case is 4.5 percent.

total mix curve is entered at the left at 4 percent, and a horizontal line is drawn to the right to

intersect the curve. From this inter section, a line is drawn vertically down to the percent AC

line, where AC is found to be 5 percent.

Thus, the curve is entered at the left at 75 percent and a horizontal line is drawn to the right to

intersect the curve and down to the percent AC line. In this example the value is 4.9 percent AC.
