Abstract

This paper compares 2 new methods of measuring surface strength properties that can be used both on delicate and strong crusts, and could be used in the field. Penetrometer results were analyzed to calculate the energy required for penetration. It was thus possible to demonstrate that only the spray-wetted fine aggregates had a surface that could undergo large-scale rupture by saltating sand grains. For all other surfaces, saltating particles would be unable to supply sufficient energy to rupture aggregates or the crusted surface. The results demonstrate that the small diameter penetrometer is a promisig technique for characterizing erodibility of aggregated and crusted surfaces
