3.1 The retention of an excessive amount of particles on the sieve indicates that problems may occur in handling and application of the material. Particles of asphalt retained on the sieve often are caused by agglomeration of the dispersed phase. Storage, pumping, handling, and temperature can all contribute to the formation of particles. Contamination from the tank, transport, or hose are other factors affecting particle formation.
1.1 This test method covers the degree to which an emulsified asphalt may contain particles of asphalt or other discreet solids retained on a 850-μm mesh sieve.
