Classification TEST

Scope

This method describes the procedure for determining the relationship between the particle size distribution of fine and coarse aggregates and fine grained soils for all construction except concrete construction.

Sample
Obtain a sample from plant or other source as described in STP 105 or as otherwise directed.
Mix sample well and break up any clay lumps; especially in fine grained materials.
Use a quartering method or sample splitter to reduce sample to appropriate test size as shown in the table. Do not adjustment sample to the exact value.

Required Materials and Equipment



-Balance - sensitive to 0.1 g.
-Sieves - Canadian Metric Standard square mesh sieves of size as required for the type of gradation for the material being tested.
-Mechanical sieve...
