ROAD COMPACTION: Under pressure

The measurement takes only a few seconds. Preparation of the sample is relatively quick as well, but the sample is disturbed, not necessarily directly representing in situ conditions. The WP4C measures the dewpoint potential of a sample of soil, and this is then related thermodynamically to the water potential of the soil sample.
