Using the Light Weight Deflectometer to Assess Groomed Snow and Ice Surfaces

摘要

The Light Weight Deflectometer (LWD) was designed to test the compaction or bearing capacity of in-place aggregate base-course materials. This study evaluated the potential of the LWD to also characterize groomed snow and ice surfaces as the ability to characterize the strength, or bearing capacity, of winter surfaces is crucial for evaluation of vehicle mobility in cold climates.
