Sand Equivalent Test Method Explained and The Process
What is the purpose of the sand equivalent test? Fines and dust in asphalt and concrete aggregates have always been a problem Whether naturally occurring or resulting from degradation during handling and transport,• Typical sand equivalent values range from less than 30% to more than 90% • If agg #1 has SE = 70% and agg #2 has SE = 40 % that means agg #1 has more sand and lessSand Equivalent Value of Soils and Fine Aggregate
