Split Consistency Test

Trial mixes are made in accordance with ISSA TB 113 to estimate optimum water contect, filler requirements and mix workability.

Cone consistency tests are made in accordance with ISSA TB 106 to optain optimum water contents at three levels of emulsion.

Optimum consistency specimens of between 2 and 3 cm outflow are air dried to constant weight or placed in air forced draft ovens 15 hours at 60°C and cooled. These specimens are vertically split across the diameter of the specimen by projecting half the specimen over a sharp table edge and breaking with pressure form the hands.

The broken edge of the consistency specimen is exmined for evidence of asphalt or aggregate migration.
