The surface nuclear gauge is found suitable for measuring soil compaction in soils with less than 5% organic matter by weight and at a depth of no more than 0.15 m (6 in.). Penetrometer readings are often unreliable on compacted soils, as well as in dry and stony soil conditions. Therefore, the penetrometer is rarely a valuable device on construction sites as a definitive measurement instrument, but it may be useful as an indicator of compacted areas. Recommendations to measure soil compaction on construction sites are given. ER -
