- •
Suggestions are presented to improve Hamburg Wheel Tracking Device (HWTD) test.
- •
2D-MMFE analysis has demonstrated significant gap/bonding and specimen shape effects on test results.
- •
The analysis suggests the best method for defining the “rut depth” to ensure consistent results.
- •
Rut depths should be collected from stations near the centers of specimens.
- •
