PROCEDURE 1. The sample must all pass through a 4.75 mm sieve and be in a slightly damp condition. Where the sample has been separated from a coarser material (such as 40 mm base course) care must be taken to collect all fines adhering to the larger stones.
filexlib. The two basic tests that determine the cleanliness of the aggregates are the sand equivalent test and the methylene blue test. In the present paper, firstly, a reference is being made to

Procedure 6. After loosening the material from the bottom of the cylinder, shake the cylinder and contents by any one of the following methods: c. Hand Method – Method not recognized by WSDOT. 10. Clay and sand readings: Replace step d with below: e. If two Sand Equivalent (SE) samples are run on the same material and the second
Sand Equivalent test is important because it is a simple test to determine whether a particular aggregate has enough dust or plastic fines to make a HMA mixture unstable or susceptible to stripping is valuable in preventing the manufacture of poor performing mixtures. In the sand equivalent test: Solution reading
sand equivalent is the ratio of the height of sand to the height tainer and rinse both with clear water. The irrigator tube and of clay times 100. siphon assembly can be rinsed easily by attaching a hose between the tip of the irrigator tube and water faucet and 5. Significance and Use backwashing fresh water through the tube.
SAND EQUIVALENT TEST FOP FOR AASHTO T 176 . Scope . This procedure covers the determination of plastic fines in accordance with AASHTO T 176-08. It serves as a rapid test to show the relative proportion of fine dust or clay-like materials in fine aggregates (FA) and soils. Apparatus . See AASHTO T 176 for a detailed listing of sand equivalent
a test method is presented which provides a rapid method for detecting the presence or absence of detrimental fines or clay-like materials in soils and mineral aggregates. THE RELATIVE PROPORTIONS OF FINE MATERIAL AND SAND ARE COMPARED ON AN ARBITRARY VOLUME BASIS BY A SIMPLE TEST PROCEDURE WHICH TENDS TO MAGNIFY OR EXPAND THE VOLUME OF CLAY
North Dakota T 176.Produced in cooperation with the Upper Great Plains Transportation Institute at NDSU Prepare sand equivalent test samples from the material passing the 4.75 mm (No. 4) sieve. If the material is in clods, break it up and re-screen it over a 4.75 mm (No. 4) sieve. All fines shall be cleaned from particles retained on the 4.75 mm (No. 4) sieve and included with the material passing that sieve.

The sand-equivalent test provides a quick means for separating the finer clay-like particles from the coarser grains or sand sizes and the relative proportions are compared on an arbitrary volume basis by a simple procedure which tends to magnify or expand the volume of clay somewhat in proportion to its deteri- mental or objectionable effects.
