Sand Equivalent Pavement Interactive

The standard sand equivalent test is: AASHTO T 176: Plastic Fines in Graded Aggregates and Soils by Use of the Sand Equivalent Test; ASTM D 2419: Sand Equivalent Value of Soils and Fine Aggregate; Background. Excessive dust or plastic fines (clay-like fine particles) in HMA aggregate can contribute to a lack of stability (rutting or shoving) or moisture damage and stripping.

Standard Test Method for Sand Equivalent Value of Soils

5.2 A minimum sand equivalent value may be specified to limit the permissible quantity of claylike or clay size fines in an aggregate. 5.3 This test method provides a rapid field method for determining changes in the quality of aggregates during production or placement.

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.

Sand equivalent test Wikipedia

The sand equivalent test quantifies the relative abundance of sand versus clay in soil. It is measured by standardized test methods such as ASTM D2419, AASHTO T176, and EN 933-8. The test is used to qualify aggregates for applications where sand is desirable but fines and dust are not.

Equivalent Sand an overview ScienceDirect Topics

Sand equivalent is used to test clay content, which is the percentage of clay material contained in the aggregate fraction that is finer than a 4.75 mm sieve. It is measured by ASTM D2419: Standard Test Method for Sand Equivalent Value of Soil and Fine Aggregate, or AASHTO T176: Plastic Fines in Graded Aggregates and Soils by Use of the Sand

Sand Equivalents Quality in California

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.
