As far as Atterberg limits, the LL criterion was not considered in this study because: (1) not many state highway agencies require this limit and (2) if the aggregate material has PI of less than 9%, it is less likely to encounter LL of more than 25%.

Limit (LL) or Plasticity Index (PI), the Atterberg Limits must be determined for each 6,000 tons of material shipped. The Liquid Limit is defined as the moisture content at which a soil passes from a plastic state to a liquid state and is determined by AASHTO T 89.

Fine material is a less desirable product and therefore there is a limit to the amount that can be accepted. If the reduction is too low there will also be fewer shaped particles. However, a comparison of VSI and cone crushed aggregate from a medium chamber reveals little difference in terms of yield.

As a result, instable aggregates crush in the water and fall through the sieve. The weight of aggregates left on the sieve is determined before they are crushed using a sodiumdiphosphate dilution to determine the stable aggregates during a second sieving. Then, the aggregate stability As is computed (Table 3).
