Search Profile Data Download Rut Depth Data: Rutting-LFS TRANSVERSE PROFILES
AND RUT DEPTHS AT THE NAPTF Transverse
Profiles Transverse
profile measurements were made at regular intervals to track the
structural deterioration of the flexible test items. The measurements were
made with a rolling inclinometer device (CSC Profilair Profilite 300). The
CSC Profilair Digital Profilite 300 is a manually propelled inertial
profiling device. The device was used to measure transverse surface
elevation profiles on the NAPTF test items. Specifications for the device
in the configuration being used were as follows: 1.
Recommended test speed = 2 km/h. 2.
Profile elevation recorded once every 250 mm (9.84 inches). 3. The elevation profiles saved in comma delimited ASCII electronic files (that can be downloaded and graphed/plotted using MS Excel or similar programs). The file names have the format XXXX-DDMMhhmm, where
XXXX = longitudinal position identifier (described below) 4. The profiles are normalized to set the first and last elevations to zero. 5.
The elevations are stored in files in unites of inches. Positive numbers
signify distances above the datum end points. Two
profiles were measured in each test item along a line marked on the
pavement. 1. In the rigid test items, the first line was along the centerline of the third (center) row of slabs. The second line was approximately two inches on the West side of the East transverse joints of the same row of slabs.
Location
of Profile Lines in Rigid Test Item 2. In the flexible test items, the lines were at the one-third points along the test items about six inches to the West side of the MDDs.
