Profiler Data/Rut Depths (HMA)
PAVEMENT PERFORMANCE DURING
TRAFFIC TESTING
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.
