Apr 30, 2011· So if your sample has a 90 sand equivalent that means that 90% of the sample was good material and 10% was detrimental. If you have a 40 sand equivalent that means that 40% of the sample was good material and 60% was detrimental. Many materials such as concrete sands will have high SEs, in the 80s or 90s but it is very rare to see a 100 SE.

Sand Equivalent Value of Soils and Fine Aggregate Categories of Soils based on Particle Size: o Coarse aggregate. o Fine aggregate. o Silt. ( sieve #200, size 0.075) o Clay. Clay like material are small particles in the size of clay particles that are deleterious to asphalt concrete and cause many problems such as: o Rutting.
test maximum limit in the Standard appears to be high. It is recommended that a lower limit be adopted to identify higher quality material. Both the Degradation Factor and the Sand Equivalent appear to measure clay activity and clay quantity contained either in the product grading or liberated from rock particles by agitation.

The sand equivalent test is used to limit the presence of clay material in the aggregate. The sand equivalent test (AASHTO T176; ASTM D2419) is a rapid field test to show the relative proportions of fine dust or clay-like materials in fine aggregate (or granular soils).
Aggregates for Concrete bination of gravels or crushed stone with particles predominantly larger than 5 mm (0.2 in.) and generally between 9.5 mm and 37.5 mm (3⁄ 8 in. and 11⁄ 2 in.). Some natural aggregate deposits, called pit-run gravel, consist of gravel and sand that can be readily used in concrete after minimal processing. Natural ...
