What is the significance of ten percent fines value in ...

This test is very similar to Aggregate Crushing Test in which a standard force 400kN is applied and fines material expressed as a percentage of the original mass is the aggregate crushing value. Granular subbase is subjected to repeated loadings from truck types. The stress level at the contact points of aggregate particles is quite high.

Permeability of Granular Subbase Materials

Jul 02, 1991· the removal of the. pavement for crushing. This old material was very poor in quality and added fines to the subbase which reduced the permeability. We made another change in the gr~dation that should improve the permeability. The change calls for a maximum of 20% passing the 8 sieve. This material is being produced and used on the project.
