CC3 Traffic Testing Results and Analysis


Two blue lines were drawn at the one-third (designated as NW and SW locations) and two-thirds (designated as NE and SE locations) distances into each pavement test item. Straightedge rut depth and surface profile measurements were made at regular intervals on these lines. In addition, surface profiles were measured at the middle of the test item. The NW and NE locations are in the north traffic lane (6-wheel traffic) and SW and SE locations are in the south traffic lane (4-wheel traffic). Figure 2 shows the straightedge rut depth measurements for the CC3 flexible test items. The rut depth data can be downloaded here.
