Potentially expansive soils can typ

Potentially expansive soils can typically be recognized in the lab by their plastic properties. Inorganic clays of high
plasticity, generally those with liquid limits exceeding 50 percent and plasticity index over 30; usually have high
inherent swelling capacity. Expansion of soils can also be measured in the lab directly, by immersing a remolded soil
sample and measuring its volume change.

Berpotensi tanah ekspansif biasanya dapat dikenali di laboratorium oleh sifat plastik mereka. Tanah liat anorganik tinggi
plastisitas, umumnya mereka dengan batas cair melebihi 50 persen dan indeks plastisitas lebih dari 30; biasanya memiliki tinggi
kapasitas pembengkakan melekat. Perluasan tanah juga dapat diukur di laboratorium secara langsung, dengan cara merendam tanah terbentuk kembali
sampel dan mengukur perubahan volumenya.
