Scheme for one-dimensional compression tests.

Sample	OCR	Load path and duration
1	1.0	37.5 kPa (1 d) ⟶75 kPa (1 d) ⟶150 kPa (7 d)
2	1.1	37.5 kPa (1 d) ⟶75 kPa (1 d) ⟶150 kPa (1 d) ⟶60.6 kPa (1 d) ⟶90.9 kPa (1 d) ⟶136.4 kPa (7 d)
3	1.2	37.5 kPa (1 d) ⟶75 kPa (1 d) ⟶150 kPa (1 d) ⟶55.5 kPa (1 d) ⟶83.33 kPa (1 d) ⟶125 kPa (7 d)
4	1.4	37.5 kPa (1 d) ⟶75 kPa (1 d) ⟶150 kPa (1 d) ⟶47.5 kPa (1 d) ⟶71.3 kPa (1 d) ⟶107 kPa (7 d)
5	1.8	37.5 kPa (1 d) ⟶75 kPa (1 d) ⟶150 kPa (1 d) ⟶37.0 kPa (1 d) ⟶55.5 kPa (1 d) ⟶ 83.3 kPa (7 d)

Note: the arrow direction in the loading path represents the next level stress. The number before the brackets is the value of the load, and the number in the brackets is the duration of the load. For example, 37.5 kPa (1 d) represents that the load is 37.5 kPa (duration is 1 day).
