For this example, the No. 8 sieve is the median sieve because it is the sieve with the percent passing closest to 50 percent. ... If the Sand Ratio is above 60.0 percent, calculate the percentage of fine aggregate contributed to the total aggregate ...
1. Prepare sand equivalent test specimens from the passing No. 4 sieve portion of the material to be tested after it has been processed according to the procedures prescribed in California Test 201, except that reclaimed aggregate containing traces of asphalt or asphalt concrete shall not be oven dried at temperatures greater than 100˚F.

Scope. 1.1 This test method is intended to serve as a rapid field correlation test. The purpose of this test method is to indicate, under standard conditions, the relative proportions of clay-size or plastic fines and dust in granular soils and fine aggregates that pass the 4.75 mm (No. 4) sieve. The term "sand equivalent" expresses the ...
The Sand Equivalent Value. The value is the ratio of the sand reading divided by the clay reading times 100. Sand Equivalent Test Apparatus. Graduated Cylinders. used for this …
local sand contains no more than % clay by weight and is free of foreign substances, roots, twigs, and other organic matter. Ensure sand is free of clay lumps, as determined by AASHTO T 112, and has a sand equivalent value exceeding 25%, as determined by GDT 63. B. Fabrication 1.
Scope. 1.1 This test method is intended to serve as a rapid field-correlation test. The purpose of this test method is to indicate, under standard conditions, the relative proportions of clay-size or plastic fines and dust in granular soils and fine aggregates that pass the 4.75-mm (No. 4) sieve. The term "sand equivalent" expresses the ...
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 …
2. Mechanical Sand Equivalent Shaker (Figure 3): a mechanical device designed to hold the sand equivalent (SE) graduated plastic cylinde r in a horizontal position while subjecting it to a reciprocating motion parallel to its length. The motion must be provided through a "scotch-yoke " mechanism, which provides a stroke length of 8 in. 0.05 in.
In France, the SE value is measured on grain sizes 0/2 mm with a maximum percentage of 10% fines. If the material contains more than 10% fines in these grain sizes, sand has to be added to lower the value. Product Standard SIST EN 13242 defines the procedure in SIST EN 933-8:2000: assessment of fines—sand equivalent test, to be …
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. [1] The test is used to qualify aggregates for applications where sand is desirable but fines and dust are not. A higher sand equivalent value indicates that …
The purpose of this test method is to indicate, under standard conditions, the relative proportions of clay-size or plastic fines and dust in granular soils and fine aggregates that pass the 4.75-mm (No. 4) sieve. The term "sand equivalent" expresses the concept that most granular soils and some fine aggregates are mixtures of desirable ...
Higher sand equivalent values indicate "cleaner" (less fine dust or clay-like materials) aggregate. 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 … See more

Sand Equivalent T 176 45 min. (b) Reclaimed Asphalt Pavement - RAP material used in the production of new ACP is optional. No more than 30 percent RAP material will be allowed in the new ACP Pavement. Use RAP Aggregates in the ACP that are no larger than the specified maximum allowable Aggregate size before entering the cold feed.
Obtain mix sample, determine weight, and place into two conical containers (with filters) Reflux Extraction. Place conical containers in cylinder. Place cylinder with solvent on hot plate. Seal top of cylinder with condenser unit. Begin reflux extraction and continue until the effluent from the lower cone is a light straw color.
This value is based on the asphalt mixture's maximum specific gravity – also known as the Rice value or G mm in Superpave. The maximum unit weight is determined by multiplying the Rice value by 62.4 pounds per cubic foot (PCF). For example, 2.500 is a typical Rice value. 2.500 X 62.4 = 156.0 PCF. Then, if 95% compaction is specified, the ...
