Bearing Capacity of 95% compacted fill Soil testing

For a well graded crushed sand and gravel (road base) I've seen as much as 400 kPa used (assuming that there is no underlying softer material within the zone of influence). We've compacted residual clayey silt to silty clay at 95% standard Proctor and obtained an effective friction angle of 32deg. Could use that to estimate bearing capacity. But one thing to keep in mind are you speakingget price

Crushed Stone Under a Spread Footing

17/12/2009 In the case of well graded aggregate, your might be able to get densities in the 140s pcf range. But for just say #57 stones, it is very unlikely to be that high. Since the soil has already been overburden with the natural soil, the increase weight that will cause settlement(due to the stones only) is how much the stone is heavier than the natural soil. Therefore, we are talking very smallget price
