Angle of Internal Friction of Crushed Stone
Angle of Internal Friction of Crushed Stone
(OP)
Hi everyone,
I am looking for friction angle of Crushed stone. The crushed stone was used in two layers as a foundation support for oil tanks. The first layer has a gradation of crushed stone between 20 to 31.5mm. The second layer has a gradation of the crushed stone between 8 to 16mm. The crushed stone were well compacted.
Could anyone advise me which friction angle for the two layer I should use for modeling? Thanks.

(Tell me you're not doing bearing capacity though as these two little sublayers are trivial compared to the bulb of shear that extends WAY below the thickness of some subbase materials.)

Don't you think 40 deg is too small? If the crushed stone is well compacted, it can be high, but may be maximum is 50deg. What do you think?
