Additional information on how the test was performed
|
The CC8 Phase 1 HWD testing was conducted prior to and after the traffic tests, encompassing various locations and purposes:
- Slab Center: HWD tests were carried out at the center of each slab to evaluate the properties of pavement layers throughout the traffic testing.
- Slab Corner: HWD tests performed at west corners of each slab to evaluate the conditions of slab support.
The HWD test utilized the FAA KUAB Mode 150 with one sensor under the load plate, one sensor at 12 inches in front of the load plate and six sensors located behind the load plate at 12-inch intervals. At each test location, four drops were applied with a target loading sequence of: 4,700 lbs., 8,000 lbs., and 12,000 lbs. with an approximate 12,000-lb seating load. Figure below shows the HWD drop locations.
