Here's a site with links to downloadable references on the general topic
http://www.vulcanhammer.net/download/general_soil_mechanics.php

In particular, this document
http://www.vulcanhammer.net/download/checklist.pdf
is produced by the Federal Highways Administration, and covers what's involved.

For more "textbook" kinds of presentation:here are some potential 
references on this (you might be able to find them at a library, possibly 
on interlibrary loan)
