I need some further clarification on Ballast question #92:
A soil's load bearing capacity:
A. increases with depth
B. decreases with depth
C. is not related to the depth
D. is related to only the soil type
I thought the correct answer is C because it really depends on the site conditions, type of soil, water content etc. (ie a layer of clayey soil under a later of sandy soil). Ballast says the correct answer is A, is this because typically the deeper the soil the more compact it gets?
