For soil cement the CRUSHED gravel should have poper mix of fines to larger pieces to make it as dense as possible. Add the proper amount of cement and water and mix well by some mechanical means, smooth to grade and pack it. The mix is not a slurry and is very hard to tell from damp gravel. A seal coat over the top will also help for longevity.
