PHASE II REPORT - Caltrans

4.3 If the mix does not break, the test is terminated at 10 minutes mixing and observations
made as to greater than or less than the specification level.
5.0 SIGNIFICANCE AND USE
5.1 This test method will measure compatibility and setting parameters of asphalt emulsions
and mineral aggregates.
5.2 This procedure is suggested for establishing design criteria of the mix system. In
addition, it provides a means of quality control during the production of asphalt emulsion,
mineral aggregates, and additives.
5.3 This method facilitates research and development of new combinations of raw materials.
5.4 This method documents the temperature influences on the consistency of the mixed
materials.
5.5 This method measures the affect of compositional changes on mixing.
