Westergaard Slab on Grade Soil Bearing Pressure
Westergaard Slab on Grade Soil Bearing Pressure
(OP)
Can anyone verify with a 3,000 pound wheel load in the center of a 5 inch slab on grade that it transmits a maximum soil bearing pressure of just 150 psf. Westergaards formula is based on a radius of relative stiffness and a soil modulus. The soil k value I used was 300pci. Any tips will be greatly appreciated.

Your k value of 300 pci is relatively high. What type of subbase soil do you have?
