A sandcone method is commonly used to determine the density of compacted soils. The density of the compacted soil calculated from the sandcone method could be correct, provided the calibration container has approximately the same size or volume and allows the sand to fall to approximately the same height as a test hole in the field.
Sand Cone Test Kepadatan di lapangan adalah kepadatan yang dihasilkan oleh mesin pemadat misalnya: Tandem Roller, Sheep Foot, Roller, dll. Untuk memeriksa kepadatannya banyak metode yang digunakan, tetapi yang paling sering dipakai adalah metode Pasir Kerucut (Sand Cone Method).
