WebThe testing process, either Australian Standard, ASTM or ISO standards, say (our words) to: (i) slowly (6° per minute) rotate to beyond peak strength; then (ii) rapidly rotate several times; then (iii) continue at the same slow speed until a “uniform residual value" is reached. At IGS we have seen hundreds, maybe thousands, of vane tests. Weba one-to-one relation between sensitivity as measured from the vane test and by the falling cone test in the laboratory. The vane appears to measure too high values for the remoulded undrained shear strength. On the other hand, work on deducing disintegration energy from the shear vane tests show promising results. ec-px200 止まる https://aufildesnuages.com
