APPENDIX B. DEFLECTION BELOW LOAD AND AT 60 INCHES FOR A 9,000-LB LOAD

B.1 GROUP 5 SECTIONS

B.1.1 Section 040213 (Arizona)

This graph shows deflections under the load center plots for two test dates for the Long-Term Pavement Performance Specific Pavement Study 2 section 040213 in Arizona. Deflection is on the y-axis ranging from 0 to 10 mil, and distance is on the x-axis ranging from 0 to 500 ft. The deflection test dates were February 8, 1994, and December 15, 2004 (for a total of two plots). The deflections on the final date are slightly higher than those on the first date at all test locations, ranging between 4 and 5 mil and between 3 and 4 mil, respectively.

Figure 107. Graph. Deflection at 0 inches for a 9,000-lb load, section 040213 (Arizona).

This graph shows deflections at 60 inches from the load center plots for two test dates for the Long-Term Pavement Performance Specific Pavement Study 2 section 040213 in Arizona. Deflection is on the y-axis ranging from 0 to 5 mil, and distance is on the x-axis ranging from 0 to 500 ft. The deflection test dates were February 8, 1994, and December 15, 2004 (for a total of two plots). The deflections on the final date are slightly higher than those on the first date at all test locations, ranging between 1.5 and 2.2 mil and between 1.2 and 1.5 mil, respectively.

B.1.2 Section 050217 (Arkansas)

This graph shows deflections under the load center plots for two test dates for the Long-Term Pavement Performance Specific Pavement Study 2 section 050217 in Arkansas. Deflection is on the y-axis ranging from 0 to 10 mil, and distance is on the x-axis ranging from 0 to 500 ft. The deflection test dates were November 14, 1996, and September 20, 2004 (for a total of two plots). The deflections on the final date are similar to those on the first date at most test locations, with values ranging between 1.5 and 4 mil.

Figure 109. Graph. Deflections at 0 inches for a 9,000-lb load, section 050217 (Arkansas).

This graph shows deflections at 60 inches from the load center plots for two test dates for the Long-Term Pavement Performance Specific Pavement Study 2 section 050217 in Arkansas. Deflection is on the y-axis ranging from 0 to 5 mil, and distance is on the x-axis ranging from 0 to 500 feet. The deflection test dates were November 14, 1996, and September 20, 2004 (for a total of two plots). The deflections on the final date are similar to those on the first date at most test locations, with values ranging between 0.9 and 3.6 mil.

B.1.3 Section 390205 (Ohio)

This graph shows deflections under the load center plots for two test dates for the Long-Term Pavement Performance Specific Pavement Study 2 section 390205 in Ohio. Deflection is on the y-axis ranging from 0 to 10 mil, and distance is on the x-axis ranging from 0 to 500 ft. The deflection test dates were December 30, 1996, and September 9, 2004 (for a total of two plots). The deflections on the final date are slightly higher than those on the first date at all test locations, ranging between 3.9 and 5.6 mil and between 2.9 and 3.9 mil, respectively.

Figure 111. Graph. Deflections at 0 inches for a 9,000-lb load, section 390205 (Ohio).

This graph shows deflections at 60 inches from the load center plots for two test dates for the Long-Term Pavement Performance Specific Pavement Study 2 section 390205 in Ohio. Deflection is on the y-axis ranging from 0 to 5 mil, and distance is on the x-axis ranging from 0 to 500 ft. The deflection test dates were December 30, 1996, and September 9, 2004 (for a total of two plots). The deflections on the final date are slightly higher than those on the first date at all test locations but one, with values ranging between 1.1 and 2 mil and between 1.1 and 1.4 mil, respectively.
