  • Sand Equivalent – Pavement Interactive

    OverviewBackgroundTest DescriptionThe sand equivalent test (Figure 1) is a rapid field test to show the relative proportions of fine dust or clay-like materials in fine aggregate (or granular soils). The term “sand equivalent” expresses the concept that most fine aggregates are mixtures of desirable coarse particles (e.g., sand) and generally undesirable clay or plastic fines and dust (ASTM, 2003).These materials can coat aggregate particles and prevent proper asphalt binder-aggregate bonding. In the sand equivalent test, a sample of aggregate p
  • Section 802 Aggregates for Asphaltic Concrete

    Sand Equivalent Use these sand equivalent values: 4. Mica Use fine aggregate with no more than 35 percent free mica in asphaltic concrete surface mixes.

  • Sand Equivalent Value of Soils and Fine Aggregate

    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%. If agg. #1 has SE = 70% and agg. #2 has SE = 40 % that means agg. #1 has more sand and less clay like material than agg. #2.

    Oct 17, 2015  Calculate the sand equivalent to the nearest 0.1% using the following formula: SE= (Sand Reading/Clay Reading)*100% Cleaner aggregates will have a higher SE value. Specifications generally call for a minimum SE on the order of 25 to 35%.
