Re: SLAB ON GRADE: Truck Wheel Load

[Subject Prev][Subject Next][Thread Prev][Thread Next]
If you have wheel loads (and distribution), the actual contact area can be determined from those weights and the tire pressure. i.e., Contact Area = wheel load/tire pressure.  If you have actual weights, you should be able to determine the tire widths associated with those weights by observing the typical tires on the trucks you've weighed.

H-20 and HS-20 axle load is 32k. 

Tire contact area is a rectangle w/ length in direction of traffic = 10” and tire width = 20”.




Thanks, Candi.


I'm assuming that this would work out to Wheel Load = 32,000#/2 = 16,000#, and Tire Pressure = 16,000#/(10")(20") = 80 psi.


That's important because we're using a lesser load for grade slab design for "chicken trucks" based on typical weigh values, and I want to make sure I got the contact area correct.


Thanks once again.
