Are there any research papers showing the Astm standard infiltration test is good or bad?

Anyone have a good reference to calculate bearing capacities for unpaved roads/parking areas?

I have been going round and round with geologists in Peru about what exactly Lutite is. Can anyone tell me or point me into the right direction.
