So the soil classiifcation encountered in the trench would not change the trench bedding design? For example, If I went from an OSHA "B" soil to an OSHA "C" soil the trench bedding detail would not have to be modified?
Thanks,
The slurry composition is a 3/4 sack sand slurry. I'm looking for the engineering criteria that would require a change in the trench bedding zone of a buried 60" water line.
For instance, when is it permittable to use a sand bedding, a slurry bedding, a concrete saddle bedding, etc.
