Does 6" asphalt provide a "constrained" foundation?
Does 6" asphalt provide a "constrained" foundation?
(OP)
I'm looking at installing a large column foundation in a paved area and I'm referring to the CBC section 1805.7.2.2 where it states:
"The following formula shall be used to determine the depth of (foundation) embedment required to resist lateral loads where constriant is provided at the ground surface, such as a rigid floor or pavement."
Is asphalt rigid?
If so....how thin can it get before it's not considered rigid?
Thanks

To estimate foundation depth you might try starting with a depth of rotation by considering about 2 feet of soil inactive from top of grade and using the Ruttledge Method to estimate foundation depth. Otherwise there are several (some pricey) software programs out there if you have an idea of lateral subgrade modulus. Some consider LPILE the gold standard.
Hope this helps.
