minimum requiremnts for sand equivalent for concrete

Sand Equivalent Pavement Interactive

The sand equivalent test is meant to be a rapid field test. Specific issues with the sand equivalent test are: The sand equivalent test is not a direct measure of a HMA physical property. Rather, it is a measure of plastic fines and dust in the aggregate. These items may contribute to a

Sand Equivalent Value of Soils and Fine Aggregate

sand reading clay reading • If the calculated sand equivalent is not a whole number, report it as the next higher whole number. • Higher sand equivalent values indicate “cleaner” (less fine dust or clay-like materials) aggregate. • Typical sand equivalent values range from less than 30% to more than 90%.
