Figure 81. Force-deflection behavior as a function of grade, moisture content, and temperature. Graphs.

Variation by Grade.

This first graph shows three distinct lines. The first line is colored red and is labeled A 1 Default. The second is black and is labeled B DS-65. The third is blue and is labeled C Clear. The vertical axis of this graph ranges from zero to 100 and represents Force in kilonewtons while the horizontal axis ranges from zero to 200 and represents Displacement in millimeters. All three lines begin at the points of zero on both axes. Line A ascends to the point of 44 on the vertical axis and 25 on the horizontal axis where it then descends and comes to an end at the points of 13 on the vertical axis and 185 on the horizontal axis. Line B ascends to 70 on the vertical and 45 on the horizontal axis where it then descends and come to an end at the points of 24 on the vertical axis and 185 on the horizontal axis. Line C ascends to 80 on the vertical and 58 on the horizontal axis where it then descends and comes to an end at the points of 16 on the vertical axis and 185 on the horizontal axis.

Variation by Moisture.

This second graph shows four distinct lines. The first line is colored red and is labeled A 30 percent Default. The second is black and labeled B 20 percent. The third is blue and labeled 10 percent. The fourth and final line is pink and labeled 1 percent. The vertical axis of this graph ranges from zero to 100 and represents Force in kilonewtons while the horizontal axis of this graph ranges from zero to 200 and represents Displacement in millimeters. All four lines begin at the point of zero on both axes. Line A spikes to 43 on the vertical axis and 25 on the horizontal axis where it then drops to 15 on the vertical axis and 35 on the horizontal axis. From this point the line runs unevenly across the graph, descending slightly and comes to an end at 14 on the vertical axis and 190 on the horizontal axis. Line B spikes to the point of 60 on the vertical and 25 on the horizontal axis where it then drops to 16 on the vertical axis and 35 on the horizontal axis. From this point the line runs unevenly across the graph, descending slightly and comes to an end at 16 on the vertical axis and 190 on the horizontal axis. Line C spikes to the point of 95 on the vertical and 25 on the horizontal axis where it then drops to 14 on the vertical axis and 35 on the horizontal axis. From this point the line runs unevenly across the graph, descending slightly and comes to an end at 14 on the vertical axis and 190 on the horizontal axis. Line D spikes to the point of 70 on the vertical and 20 on the horizontal axis where it then drops to zero on the vertical axis and 22 on the horizontal axis. From this point the line runs unevenly across the bottom graph, and comes to an end at 1 on the vertical axis and 190 on the horizontal axis.

Variation by Temperature.

This third graph shows four distinct lines. The first line is colored red and is labeled A 30. The second is black and labeled B 20 default. The third is blue and labeled C 10. The fourth and final line is pink and labeled D 1. The vertical axis of this graph ranges from zero to 100 and represents Force in kilonewtons while the horizontal axis of this graph ranges from zero to 200 and represents Displacement in millimeters. All four lines begin at the point of zero on both axes. Line A ascends to the point of 40 on the vertical axis and 25 on the horizontal axis before dropping to 16 on the horizontal axis where it runs unevenly across the remainder of the graph, descending slightly and coming to an end at the point of 14 on the vertical axis and 190 on the horizontal axis. Line B ascends to the point of 43 on the vertical axis and 25 on the horizontal axis before dropping to 16 on the horizontal axis where it runs unevenly across the remainder of the graph, descending slightly and coming to an end at the point of 15 on the vertical axis and 190 on the horizontal axis. Line C ascends to the point of 45 on the vertical axis and 25 on the horizontal axis before dropping to 16 on the horizontal axis where it runs unevenly across the remainder of the graph, descending slightly and coming to an end at the point of 17 on the vertical axis and 190 on the horizontal axis. Line D ascends to the point of 47 on the vertical axis and 25 on the horizontal axis before dropping to 16 on the horizontal axis where it runs unevenly across the remainder of the graph, descending slightly and coming to an end at the point of 19 on the vertical axis and 190 on the horizontal axis.
