Wheel Load Stress Distribution and Different Soild Types
Wheel Load Stress Distribution and Different Soild Types
(OP)
I am looking for a reference that deals with stress distribution as it relates to different soil types. I have read that a load applied to the surface of a material such as crushed rock, can yield stresses on a subgrade at depth of up to 1/2 of that of some other materials (i.e sand). I am looking for some way to quantify this relationship in order to assess the cost benefit of using a more expensive
road ballast on a soft clay subgrade (i.e. less material of higher quality).

Using different material properties, this allows you to compute orthogonal stresses at any point below or near the load. Very useful in pavement analysis.
Yoder and Witzcak is a good reference. If you use that one, I think the elastic layer technique is only good for two layers, so you will have to go further to evaluate more materials.
