Civil Engineering: Thickness of roadbase

AI Thread Summary
To determine the appropriate thickness of a roadbase for a 7-tonne rig exerting 350 kPa on sand, factors such as the type of material (crushed concrete or crushed sandstone) and soil characteristics must be considered. Calculating the required thickness involves assessing load distribution and the bearing capacity of the underlying sand. Engineering principles, including the use of empirical formulas or design charts, can guide the thickness determination. It's essential to ensure that the roadbase can adequately support the weight without excessive deformation or failure. Seeking expert advice or consulting engineering resources may provide further clarity on the calculations needed.

Hi All,

I got this tute question that I need help with.

I need to determine the thickness of a roadbase (can be anything from crushed concrete or crushed sandstone) on top of sand to withhold a 7tonne rig (350kpa).

Any help would be most appreciated.

Thank you!
