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.

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.

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 Vs Silt Content Test Concrete

Hi, What is the difference between sand equivalent test values and sa simple silt content test? I mean when you finish a SE test, specs say that min 75% SE value is accepatable, which means max 25% of clay/silt content is acceptable limit for sand used in structural concrete!

What is the R-value for earth, dirt, soil, backfill, or

Some sources quote a much higher R-value for sand and gravel aggregate but you need to look at the thickness or amount of sand or gravel when you see such quots. For example some cite sand and gravel aggregate as providing R 1.11 FOR 8 INCHES of thickness. That's equivalent to an R-value of R 0.1388 per inch, but without considering moisture level.
