There are several gradation formulas that will work to form the binding effect that is needed. Below you
will find three options that have proven to be effective – ranging from a good gradation to an excellent
gradation. Any of the three should work and preferably have a fracture on the aggregate of 75% or
greater. The Plasticity Index is very important to achieve.

Note – MN Class 5 gravel can also be modified by adding clays to achieve a workable material.
We anticipate needing approximately 750-800 tons.
