Aggregate design for large forklift.

[cjudd]

I have been asked to design a lay-down yard for storing steel containers. A large forklift will be the heaviest axle load on the area in question (125 kip). The area will be graded to around 2% slope with soil from a containment berm around the site. Then a base course and running course of aggregate will be placed on top of the subgrade. The soil is CL having 119 pcf maximum dry density compacted at 12.5% moisture.

I am having trouble choosing a design method that will accurately take into account the heavy loads. Most ESAL equivalence charts only go to 50 kips. I have looked at Aggregate equivalent and structural number methods. I could use some guidance on how to proceed.

The design life is 10 years

Thanks

try soil cement or concrete

Consider elastic layer analysis. Also for these applications, roller compacted concrete is a good pavement process to use.

I have attached a paper on industrial pavement design...
