Wheel-Tracking Devices and Related Systems and Methods |
| 摘要 |
A wheel-tracking test device includes a housing, one or more test chambers in the housing, one or more load arm assemblies, and a drive mechanism. Each test chamber is configured to receive and hold one or more asphalt test samples. Each load arm assembly includes a weighted loading arm and a wheel rotatably connected to the loading arm. The drive mechanism is configured to move the load arm assembly from a load position in which the wheel is on a test sample held in the test chamber and a rest position by retracting the loading arm such that the wheel is lifted off the test sample. |
